The A Series units contain the factory-installed (_mfortLink TM control system which provides full system management. The main base board (MBB) stores hundreds of unit configuration settings and 8 time of day schedules. The MBB also performs self diagnostic tests at unit start-up, monitors the operation of the unit, and provides alarms and alert information. The system also contains other optional boards that are connected to the MBB through the Local Equipment Network (LEN). Information on system operation and stares are sent to the MBB processor by various sensors and optional boards that are located at the unit. Access to the unit controls for configuration, set point selection, schedule creation, and service can be done through a unit-mounted scrolling marquee. Access can also be done through the Carrier Comfort Network R>(CCN) system using the ComfortVIEW rM software, the accessory Navigator TM hand-held display, or the System Pilot TM interface. The (_nfortLink system controls all aspects of the rooftop. It controls the supply-fan motor, compressors, and economizers to maintain the proper temperature conditions. The controls also cycle condenser fans to maintain suitable head pressure. All VAV units are equipped with a standard VFD (variable frequency drive) for supply fan speed control and supply duct pressure control. The (_mfortLink controls adjust the speed of the VFD based on a static pressure sensor input. In addition, the (_mfortLink controls can raise or lower the building pressure using multiple power exhaust fans controlled from economizer damper position or from a building pressure sensor. The control safeties are continuously monitored to ensure safe operation under all conditions. Sensors include suction pressure transducers, discharge pressure transducers, and saturated condensing temperature sensors which allow for display of operational pressures and saturation temperatures. A scheduling function, prograimned by the user, controls the unit occupied/unoccupied schedule. Up to 8 different schedules can be progralmned. The controls also allow the service person to operate a quick test so that all the controlled components can be checked for proper operation. Conventions Used in This Manual E The following conventions for discussing configuration points for the local display (scrolling marquee or Navigator accessory) will be used in this manual. Point names will be written with the Mode name first, then any sub-modes, then the point name, each separated by an arrow symbol (--->). Names will also be shown in bold and italics. As an example, the IAQ Economizer Ovemde Position which is located in the Configuration mode, Indoor Air Quality Configuration sub-mode, and the Air Quality Set Points sub-sub-mode, would be written as (bnfiguration--€ IAQ---_IAQ.SP-_IQ.O.P. A list of point names can be found in Appendix A. This path name will show the user how to navigate through the local display to reach the desired configuration. The user would scroll through the modes and submodes using the [] and _--] keys. The arrow symbol in the path name represents pressing _ menu structure. to move into the next level of the When a value is included as part of the path name, it will be shown at the end of the path name after an equals sign. If the value represents a configuration setting, an explanation will be shown in parentheses after the value. As an example, Configuration--+IAQ---)AQ. CF--+IQ.AC = 1 (IAQ Analog Input). Pressing the _ and _ keys simultaneously at any thne will display an expanded text description of the fourcharacter point name. The expanded description is shown in the local display tables (Appendix A). The CCN point names are also referenced in the local display tables for users configuring the unit with CCN software instead of the local display. The CCN tables are located in Appendix B of this manual. BASIC ComfortLink CONTROL Controls USAGE E The (_mfortLink control system is a comprehensive unit-management system. The control system is easy to access, configure, diagnose and troubleshoot. The control is flexible, providing two types of constant volume cooling control sequences, two variable air volume cooling control sequences, and heating control sequences for two-stage electric and gas systems, and for multiple-stage gas heating, in both Occupied and Unoccupied schedule modes. This control also manages: • • • • • • • • • VAV duct pressure (through optional VFD), with reset Building pressure through two different power exhaust schemes Condenser fan cycling for mild ambient head pressure control Space ventilation control, in Occupied and Unoccupied periods, using CO2 sensors or external signals, with ventilation defined by damper position Smoke control functions Occupancy schedules Occupancy or start/stop sequences based on third party signals Alarm status and history and run time data Management of a complete unit service test sequence System diagnostics areenhanced bytheuseof multiple external sensors forairtemperatures, airpressures, refrigerant temperatures, andrefrigerant pressures.

Access to control menus isshnplified bytheabilitytoquicklyselect from 11menus. A scrolling readout provides detailed explanations ofcontrol reformation. Onlyfour,large, easy-to-use buttons are required tomaneuver through theentire controls menu. For addedserviceflexibility,an accessory hand-held Navigator module isalsoavailable. Thisportable device hasan extended colmnunication cablethatcanbeplugged intothe unit'scolmnunication network either atthemare control boxor atthe opposite end of the unit, at a remote modular plug. The Navigator display provides the same menu structure, control access and display data as is available at the unit-mounted scrolling marquee display. Scrolling Marquee -- This device is the standard interface used to access the control information, read sensor values, and test the unit. The scrolling marquee is located in the main control box. The scrolling marquee display is a 4-key, 4-character LED (light-emitting diode) display module. The display also contains an Alarm Stares LED. See Fig. 1. The display is easy to operate using 4 buttons and a group of 11 LEDs that indicate the following menu structures, referred to as modes (see Appendix A): • Run Status • Service Test • Temperatures • Pressures • Set points • Inputs • Outputs • Configuration • Timeclock • Operating Modes • Alarms Through the scrolling marquee, the user can access all of the inputs and outputs to check on their values and status, configure operating parameters plus evaluate the current decision stares for operating modes. Because the A Series units are equipped with suction pressure and saturated condensing temperature transducers, the scrolling marquee can also display refrigerant circuit pressures typically obtained from service gages. The control also includes an alarm history which can be accessed from the display. In addition, through the scrolling Fig. 2 -- Accessory Navigator Display marquee, the user can access a built-in test routine that can be used at start-up colrunissioning to diagnose operational problems with the unit. Accessory Navigator TM Display-- The accessory hand-held Navigator display can be used with the A Series units. See Fig. 2. The Navigator display operates the same way as the scrolling marquee device. The Navigator display is plugged into the RJ-14 (LEN) jack in the main control box on the COMM board. The Navigator display can also be plugged into the RJ-14 jack located on the ECB (economizer control board) located in the auxiliary control box. Operation -- All units are shipped from the factory with the scrolling marquee display, which is located in the mare control box. See Fig. 1. In addition, the (_n?fortLink TM controls also support the use of the handheld Navigator display. Both displays provide the user with an interface to the (_n_fortLink control system. The displays have [] and [] arrow keys, an IESCAPEI key and an _ key. These keys are used to navigate through the different modes of the display structure. The Navigator and the scrolling marquee operate in the same manner, except that the Navigator display has multiple lines of display and the scrolling marquee has a single line. All further discussions be based on the scrolling menu and examples in this document marquee will display. See Table 2 for the structure. The four keys are used to navigate through the display structure, which is organized in a tiered mode structure. If the buttons have not been used for a period, the display will default to the AUTO VIEW display category as shown under the RUN STATUS category. To show the top-level display, press the ]ESCAPE] key until a blank display is shown. Then use the [_ and [] arrow keys to scroll through the top-level categories (modes). These are listed in Appendix A and will be indicated on the scrolling marquee by the LED next to each mode listed on the face of the display. When a specific O mode or sub-mode is located, push the key to enter the mode. Depending on the mode, there may be additional tiers. Continue to use the _ and _ keys and the _ keys until the desired display item is found. At any time, the user can move back a mode level by pressing Alarms ©_ the ] ESCAPE] Fig. 1 -- Scrolling Marquee key. Once an item has been selected the display will flash showing the item, followed by the item value and then followed by the item units (if any). f "-, Items in the Configuration and Service Test modes are password protected. The display will flash PASS and WORD when required. Use the _ four digits of the password. and arrow keys to enter the The default password is 1111. Pressing the IESCAPEI and _ keys simultaneously will scroll an expanded text description across the display indicating the full meaning of each display point. Pressing the I ESCAPEI and _ keys when the display is blank (MODE LED level) will return the display to its default menu of rotating AUTO VIEW display items. In addition, the password will need to be entered again before changes can be made. Changing item values or testing outputs is accomplished in the same manner. Locate and display the desired item. If the display is in rotating auto-view, press the _ key to stop the display at the desired item. Press the _ key again so that the item value flashes. Use the arrow keys to change the value of state of an item and press the _ key to accept it. Press the ]ESCAPE] key and the item, value or units display will resume. Repeat the process as required for other items. If the user needs to force a variable, follow the same process as when editing a configuration parameter. A forced variable will be displayed with a blinking "f' following its value. For example, if supply fan requested (FAN.F) is forced, the display shows "YESf', where the "f' is blinking to signify a force on the point. Remove the force by selecting the point that is forced with the _ key and then pressing row keys simultaneously. the [_ and [_ ar- Depending on the unit model, factory-installed options and field-installed accessories, some of the items in the various Mode categories may not apply. System Pilot TM Interface E The System Pilot (33PILOT-01) device is a component of Carrier's 3V rM system and serves as a user-interface and configuration tool for all Carrier COlrnnunicating devices. The System Pilot device can be used to install and COlmnission a 3V zoning system, linkage compatible air source, universal controller, and all other devices operating on the CCN system. Additionally, the System Pilot device can serve as a wall-lnounted telnperamre sensor for space telnperamre measurement. The occupant can use the System Pilot device to change set points. A security feature is provided to limit access of features for unauthorized users. See Fig. 3 for System Pilot details. CCN Tables and Display E In addition to the unitmounted scrolling marquee display, the user can also access the same inforlnation through the CCN tables by using the Service tool or other CCN programs. Details on the CCN tables are SUlnmarized in Appendix B. The variable names used for the CCN tables and the scrolling marquee tables may be different and more items are displayed in the CCN tables. As a reference, the CCN variable names are included in the scrolling marquee tables and the scrolling marquee names are included in the local display tables in Appendix B. NAVIGATE/_ EXIT \ "!? / o \ -MODIFY/ SELECT J SCROLL _ PAGE Fig. 3 -- System Pilot TM User Interface GENERICS STATUS DISPLAY TABLE -- The GENERICS points table allows the service/installer the ability to create a custom table in which up to 20 points from the 5 CCN categories (Points, Config, Service-Config, Set Point, and Maintenance) may be collected and displayed. In the Service-Config table section, there is a table named "generics". This table contains placeholders for up to 20 CCN point names and allows the user to decide which points are displayed in the GENERICS points table under the local display. Each one of these placeholders allows the input of an 8-character ASCII string. Using a CCN interface, enter the Edit mode for the Service-Config table "generics" and enter the CCN name for each point to be displayed in the custom points table in the order they will be displayed. When done entering point names, download the table to the rooftop unit control. IMPORTANT: The computer system software (ColnfortVIEW TM, Service Tool, etc.) that is used to interact with CCN controls always saves a template of items it considers as static (e.g., limits, units, forcibility, 24-character text strings, and point names) after the software uploads the tables from a control. Thereafter, the software is only concerned with run time data like value and hardware/force stares. With this in mind, it is important that anytime a change is made to the Service-Config table "generics" (which in turn changes the points contained in the GENERICS point table), that a complete new upload be performed. This requires that any prex4ous table database be completely removed first. Failure to do this will not allow the user to display the new points that have been created and the CCN interface will have a different table database than the unit control.

This point indicates if schedule 1 applies to Monday. Use the ENTER colrnnand to go into Edit mode, and use the UP or DOWN key to change the display to YES or NO. Scroll down through the rest of the days and apply schedule 1 where desired. The schedule can also be applied to a holiday. Press ESCAPE. 6. The first schedule is now complete. If a second schedule is needed, such as for weekends or holidays, scroll down and repeat the entire procedure for period 2 (PER.2). If additional schedules are needed, repeat the process for as many as are needed. Eight schedules are provided. IAQ Demand Vent Min.Pos. Configuration -+IAQ-+DCV..C-+IAQ.M is used to set the absolute lninimum vent position (or maximum reset) under DCV. Configuration-+IAQ-+DCV.C-+EC.MN is used to set the minimum damper position (or with no DCV reset). This is also referenced in the economizer section. Exhaust Options E The A Series units can be configured with constant volume 2-stage power exhaust or modulating power exhaust. The following exhaust options should be configured. Configuration-+BP-+BECF=l (Two-Stage Exhaust -- For two-stage exhaust, under the Configuration --+BP submenu, configure the following: BRP1 Power Exhaust On Setp. 1 BRP2 Power Exhaust On Setp.2 SERVICE General -- The units are equipped with a Service Test feature, which is intended to allow a service person to force the unit into different modes of operation to test them. To use this feature, enter the Service Test category on the local display and place the unit into the test mode by changing Service Test-+TESTfrom OFF to ON. The display will prompt for the password before allowing any change. The default password is 1111. Once the unit enters the Service Test mode, the unit will shut down all current modes. Con.figuration --+BP--+BE CF=2 (Modulating Power Exhaust -- For modulating exhaust, in the Configuration-+ BP submenu, configure the following: BRSP Programming Building Pressure Setp. Operating Schedules E The (_,fortLink TM controls will accolmnodate up to eight different schedules (Periods 1 through 8), and each schedule is assigned to the desired days of the week. Each schedule includes an occupied on and off tflne. As an example, to set an occupied schedule for 8 AM to 5 PM for Monday through Friday, the user would set days Monday through Friday to ON for Period 1. Then the user would configure the Period 1 Occupied From point to 08:00 and the Period 1 Occupied To point to 17:00. To create a different weekend schedule, the user would use Period 2 and set days Saturday and Sunday to ON with the desired Occupied On and Ofttimes. To create a schedule, perform the following procedure: TEST-The TEST colranand turns the unit off (hard stop) and allows the unit to be put in a manual control mode. STOPThe STOP colranand completely disables the unit (all outputs turn off ilranediately). Once in this mode, nothing can ovemde the unit to turn it on. The controller will ignore all inputs and colmnands. S.STP Setting Soft Stop to YES turns the unit off in an orderly way, honoring any time guards currently in effect. FAN.F-By turning the FAN FORCE on, the supply fan is turned on and will operate as it normally would, controlling duct static pressure on VAV applications or just energizing the fan on CV applications. To remove the force, press ENTER and then press the UP and DOWN arrows shnultaneously. NOTE: By default, the tflne schedule periods are progralmned for 24 hours of occupied operation. 1. Scroll to the Configuration mode, and select CCN CONFIGURATION (('(Pc). Scroll clown to the Schedule Number (Configuration _CCN-+SC OV-+SCI-I.N). If password protection has been enabled, the user will be prompted to enter the password before any new data is accepted. S(7-!.N has a range of 0 to 99. The default value is 1. A value of 0 is always occupied, and the unit will control to its occupied set points. A value of 1 means the unit will follow a local schedule, and a value of 65 to 99 means it will follow a CCN schedule. Schedules 2 to 64 are not used as the control only supports one internal/local schedule. If one of the 2 to 64 schedules is configured, then the control will force the number back to 1. Make sure the value is set to 1 to use a local schedule. 2. 3. TEST E4.CH-The 4-Inch Filter Change Mode variable is used to service the unit when 4-in. filters are used. When the filters need to be changed, set Service Test-+E4. (7-/= YES. The unit will be placed in Service Test mode and the economizer will move to the 40% open position to facilitate removal of the 4-in. filters. After the filters have been changed, set Service Test-+E4.CI-I= NO to return the unit to normal operation. The remaining categories: INDP, FANS, COOL, HEAT are sub-modes with separate items and functions. Table 41. Service Test Mode Logic and See -- Operation in the Service Test mode is sub-mode specific except for the Independent submode. Leaving the sub-mode while a test is being performed and attempting to start a different test in the new sub-mode will cause the previous test to terminate. When this happens, the new request will be delayed for 5 seconds. For example, if compressors were turned on under the COOL sub-mode, any attempt to turn on heating stages within the HEAT sub-mode would ilranediately turn offthe compressors and, 5 seconds later, the controller would honor the requested heat stages. Enter the Time Clock mode. Scroll down to the LOCAL TIME SCHEDULE (SCH.L) sub-mode, and press ENTER. Period 1 (PER.l) will be displayed. Press ENTER to configure Period 1. Configure the beginning of the occupied thne period for Period 1 (O('(). Scroll down to O('(' and press ENTER to go into Edit mode. The first two digits of the 00.00 will start flashing. Use the UP or DOWN key to display the 29 Howevec it is important tonotethattheusercanleavea Service Test]nodetoviewanyofthelocaldisplay modes and thecontrol willremain in the Service Test ]node. individually. After starting each compressor, the control will check the suction pressure after 5 seconds of run time. If the control does not see a sufficient decrease in suction pressure after 5 seconds, mechanical cooling will be shut down, and an alarm will be generated (A140). This alarm requires a manual reset. If this alarm occurs, do not attempt a restart of the compressor and do not attempt to start any other compressors until the wiring to the unit has been corrected. Independent Outputs -- The INDP sub-mode items can be turned on and off regardless of the other category states. For example, the alarm relay can be forced on in the INDP sub-mode and will remain on if compressor relays are requested in the COOL sub-mode. Fans in Service Test Mode -- Upon entering Heating in Service Test Mode _ If unit has a thermostat connected (C TYP = 3 or 4), install the RED jumper the FANS sub-mode, the user will be able to turn the supply fan on and off, set the supply fan VFD speed, and turn the condenser fans on and off. Cooling in Service Test Mode -- wires between TB4, terminals R (1), W2 (3) and Wl (4). Terminal block TB4 is located in the unit control box. Remember to disconnect these jumpers when Test Mode is completed. The Heat Test Mode sub-mode will offer automatic fan start-up if the unit is not a gas heat unit. On gas heat units, the IGC feedback from the gas control units will bring the fan on as required. The COOL sub- ]node offers different cooling service tests. The user has manual relay control of individual compressors. If the user energizes mechanical cooling, the supply fan and the outdoor fans will be started automatically. During mechanical cooling, the unit will protect itself. Compressor diagnostics are active, monitoring for high discharge pressure, low suction pressure, etc. The user can also turn the hot gas bypass valve on and off. Within this sub-mode, the user has control of heat relays 1 to 6. The user can also turn on the requested heat stage. NOTE: When service test has thermostat connected (CTYP jumper wires at TB4, terminals Terminal block TB4 is located these jumpers in the unit control NOTE: It is crucial that proper compressor rotation be verified during the service test.

In either case, it will be necessary to install a controls expansion module (CEM). DEMAND LIMIT DISCRETE INPUTS -- First, set DM.L.S in (bnfiguration-+DMD.L to 1 (2 switches). When Inputs-cGEN.I-cDL.S1 (Demand Switch no. 1) is OFF, the control will not set any limit to the capacity, and when ON, the control sets a capacity limit to the Configuration--cDMD.L -¢D.L.S1 set point. Likewise, when Inputs-cGEN.I-cDL.S2 (Demand Switch no. 2) is OFF, the control will not set any limit to the capacity, and when ON, the control sets a capacity lflnit to the Configuration--cDMD.L--cD.L.S2 set point. If both switches are ON, Inputs-cGEN.I-cDL.S2 is used as the limiter of capacity. Under (bnfiguration--cSW..LG set the logic state appropriately for the action desired. Set the DL1.L and DL2.L configurations. They can be set normally open or normally closed. For example, ifDL1.L is set to OPEN, the user will need to close the switch to cause the control to limit capacity to the demand limit 1 set point. Likewise, if DL1.L is set to CLSE (closed), the user will need to open the switch to cause the control to limit capacity to the demand limit 1 set point. DEMAND LIMIT 4 TO 20 mA INPUT -- Under (bnfiguration--cDMD.L, set configuration DM.L.S to 2 (2 = 4 to 20 mA control). Under the same menu, set D.L.20 to a value from 0 to 100% to set the demand lflnit range. For example, with D.L.20 set to 50, a 4 mA signal will result in no limit to the capacity and 20 mA signal will result in a 50% reduction in capacity. Thermostat E The method of control would be through the thermostat inputs: Y1 = first stage cooling Y1 and Y2 = first and second stage cooling Wl = first stage heating Wl and W2 = first and second stage heating G = supply fan Alarm Output E The alarm output TB4-7 and 8, will provide relay closure whenever the unit is under an alert or alarm condition. Remote Switch _ The remote switch may be configured for three different functions. Under Configuration --+UNIT, set RM. (T" to one of the following: 0 = no remote switch 1 = occupied/unoccupied switch 2 = start!stop switch 3 = occupancy ovemde switch With RM. CF set to 1, no time schedules are followed and the unit follows the remote switch only in determining the state of occupancy. With RM. CF set to 2, the remote switch can be used to shut down and disable the unit, while still honoring tflne guards on compressors. Time schedules, internal or external, may be run simultaneously with this configuration. With RM.CF set to 3, the remote input may override an unoccupied state and force the control to go into occupied mode. As with the start/stop configuration, an internal or external time schedule may continue to control occupancy when the switch is not in effect. Demand Under (bnfiguration-+SW.LG---_RMI.L, the remote occupancy switch can be set to either a normally open or normally closed switch input. Normal is defined as either unoccupied, start or "not currently overridden," respective to the RM.CF configuration. Controlled Ventilation There are multiple methods for externally omizer damper.

Q--+IA Q.I. VFD Control _ On VFD equipped supply fans, supply duct static pressure control may be left under unit control or be externally controlled. To control a VFD externally with a 4 to 20 mA signal, set SRRS to 4, under the Configuration--+SP menu. This will set the reset to VFD control. When SRRS = 4, the static pressure reset function acts to provide direct VFD speed control where 4 mA = 0% speed and 20 mA = 100% (SRMN and SRMX will ovemde). Note that SRCF must be set to 1 (VFD Control) prior to configuring SRRS = 4. Failure to do so could result in damage to ductwork due to overpressurization. In effect, this represents a speed control signal "pass through" under normal operating circumstances. The (bnfortLink controller ovemdes the third party signal for critical operation situations, most notably smoke and fire control. Wire the input to the controls expansion module (CEM) using TB-11 and 12. An optional CEM board is required. The IAQ dis(optional) to TB5-6 and 7. be found at Before configuring the switch functionality, first determine how the switch will be read. A closed switch can indicate either a low IAQ condition or a high IAQ condition. This is set at Configuration-+SW.LG and IAQ.L. The user can set what a low reading would mean based on the type of switch being used. Setting IAQ.L to OPEN means that when the switch is open the input will read LOW. When the switch is closed, the input will read HIGH. Setting IAQ.L to CLSE (closed) means that when the switch is closed the input will read LOW, and therefore, when the switch is open the switch will read HIGH. There are two possible configurations for the IAQ discrete input. Select item (bnfiguration--clAQ--)AQ.CF--clQ.LC and configure for either 1 (IAQ Discrete) or 2 (IAQ Discrete Override). See Appendix C and the VFD literature supplied with the unit for VFD configurations and field wiring connections to the VFD. IQ.L C = 1 (IAQ Discrete) -- If the user sets IQ.L C to 1 (IAQ Discrete), and the switch logic ((bnfiguration--cSW.LG--€ IAQ.L) is set to OPEN, then an open switch reads low and a closed switch reads high. Supply Air Reset -- With the installation of the CEM, the (_mfortLink controller is capable of accepting a 4 to 20 mA signal, to reset the supply-air temperature up to a maximum of 20 E See VFD Control section above. If the switch is open, the economizer will be colmnanded the IAQ Demand Vent Minimum Position. Demand Limit Control _ The term "demand limit control" refers to the restriction of the machine's mechanical cooling capacity to control the amount of power that a machine may use. Demand limiting using mechanical control is possible via two means: to These settings may be adjusted and are located at (bnfiguration --+IAQ--+DC V.C-+IA Q.M. If the switch is closed, the IAQ reading will be high and the economizer will be colmnanded to the Economizer Minimum Position. This setting may be adjusted and is located tion --dA Q --cDC V.C-cE C MN. Two discrete inputs tied to demand lhnit set point percentages. OR 31 at Configura- IQ.LC = 2 (IAQ Discrete Override) -- If the user sets IQ.LC to 2 (IAQ Discrete Override), and Configuration-+SW..LG-+ IAQ.L is set to OPEN, then an open switch reads low and a closed switch reads high. The 4 to 20 mA signal from the sensor wired to TB5-6 and 7 is scaled to an equivalent indoor CO 2 (IAQ) by the parameters IQ.R.L and IQ.R,H located under the (bnfiguration -+IAQ-+AQ.S.R menu. The parameters are defined such that 4 mA = IQ.R,L and 20 mA = IQ.R.H. When the differential air quality DAQ (IAQ - OAQ. U) exceeds the DAQ.H set point ((bnfiguration---_IAQ---_AQ.SP menu) and the supply fan is on, the economizer lnmimum vent position ((bnfiguration --¢IAQ-+DCV.C--cECMN) is overridden and the dmnper is moved to the IQ.RO configuration. When the DAQ falls below the DAQ.L set point ((bnfiguration--+IAQ -+AQ.SP menu), the economizer damper is moved back to the lninimum vent position (E(:MN). If the switch reads low, no action will be taken. If the switch reads high, the economizer will ilrnnediately be colmnanded to the IAQ Economizer Override Position. This can be set from 0 to 100% and can be found at (bnfiguration--+IAQ---)AQ.SP--+ iQ.O.P FAN CONTROL FOR THE IAQ DISCRETE INPUT -Under Configuration--clAQ--)AQ.CF the IQ.LF (IAQ Discrete Input Fan Configuration) must also be set. There are three configurations for IQ.LF Select the configuration which will be used for fan operation. This configuration allows the user to decide (if the supply fan is not already running), whether the IAQ discrete switch will start the fan, and in which state of occupancy the fan will start. IQ.LF = 0 IQ.LF = 1 IQ.LF = 2 Minflnum Position Override will not start fan Minflnum Position Override will start fan in occupied mode Minflnum Position Override will start fan in both occupied pied modes Switch NOTE: Configuration OAQ.

IQ.A. C = 2 (IAQ Analog Input Used to Override) -- Under Configuration--clAQ--cAQ.SP, set IQ.O.P (IAQ Economizer Override Position). The IQ.O.P configuration is adjustable from 0 to 100%. These configurations are also used in conjunction with (bnfiguration --€IAQ--cA Q.CF--clQ.A. F (IAQ 4 to 20 mA Fan Configuration). There are three configurations for IQ.A.F and they follow the same logic as for the discrete input. This configuration allows the user to decide (if the supply fan is not already running), if the IAQ Analog Minimum Position Override input will start the fan, and in which state of occupancy the fan will start. IQ.A.F = 0 IQ.A.F = 1 IQ.A.F = 2 IQ.A. C = 4 (10 Kilo-ohm Potentiometer Damper Control) -- This configuration will provide input for a 10 kilo-otnn linear potentiometer that acts as a remotely controlled analog mput for economizer minimum damper position. The input is processed as 0 otnns = 0% and 10,000 otnns = 100%, thereby giving complete range control of the effective minimum position. CONTROLS Modes E The (_olIlfoplgink TM controls operate under a hierarchy of COlrnnand structure as defined by three essential elements: the System mode, the HVAC mode and the Control mode. The System mode is the top level mode that defines three essential states for the control system: OFF, RUN and TEST. The HVAC mode is the functional level underneath the System mode which further defines the operation of the control. The mode selection process is shown in Appendix D. The Control mode is essentially the control type of the unit ((bnfigurafion--cUNIT--cCTYP). This defines from where the control looks to establish a cooling or heating mode and whether 2 stages or multiple stages of cooling capacity operation are controlled. IAQ analog sensor input cannot start the supply fan IAQ analog sensor input can start the supply fan in occupied mode only IAQ analog sensor input can start the supply fan in both occupied and unoccupied modes Furthermore, there are a number of modes which operate concurrently when the unit is running. The operating modes of the control are located at the local displays under Operating Modes. See Table 42. If IQ.A.F is configured to request the supply fan, then configurations D.EON and D.EOF need to be set. These configuration settings are located under Confignration---_ IAQ--)AQ.SP and configure the fan override operation based on the differential air quality (DAQ).

Unlike traditional 2-stage space temperature control, the unit is allowed to use multiple stages of cooling control and perform VAV-type operation. The control will be able to call out a LOW COOL or a HIGH COOL mode and maintain a low or high cool supply air set point. • C. TYP = 6 (SPT-2 STG) This configuration will force the control to monitor the space temperature sensor to make a determination of mode and allow 2 stages of control for both heating and cooling. FAN MODE (CV..FN) -- The Fan Mode configuration can be used for machine control types (Configuration--€ UNIT_CTYP) 3, 4, 5, and 6. The Fan Mode variable establishes the operating sequence for the supply fan during occupied periods. When set to 1 (Continuous), the fan will operate continuously during occupied periods. When set to 0 (Automatic), the fan will run only during a heating or cooling mode. HVAC Mode -- TEMPERING HICOOL (12) -- The economizer is at minimum vent position but the combination of the outside-air temperature and the economizer position has dropped the supply-air temperature below the tempering cool set point. Staged gas heat is used to temper the ventilation air. HVAC ModeVENT (13) -- This is a normal operation mode where no heating or cooling is required and outside air is being delivered to the space to control IAQ levels. HVAC Mode -- LOW COOL (14) -- This is a normal ing mode where a low cooling demand is required. cool- HVAC Mode -- HIGH COOL (15) -- This is a normal cooling mode where a high cooling demand is required. HVAC Mode -- LOW HEAT (16) -- The unit will be in low heating demand mode using either gas or electric heat. HVAC Mode -- HIGH HEAT (17) -- The unit will be in high heating demand mode using either gas or electric heat. HVAC Mode -- UNOCC. FREE COOL (18) -In this mode the unit will operate in cooling but will be using the economizer for free cooling. Entering this mode will depend on the stares of the outside air. The unit can be configured for outside air changeover, differential dry bulb changeover, outside air enthalpy changeover, differential enthalpy changeover, or a custom arrangement of enthalpy/dewpoint and dry bulb. See the Economizer section for further details. HVAC Mode -- FIRE SHUT DOWN (19) -- The unit has been stopped due to a fire shutdown input (FSD) or two or more of the fire control modes, purge, evacuation, or pressurization have been requested shnultaneously. HVAC Mode -- PRESSURIZATION (20) -- The unit is in the special fire pressurization mode where the supply fan is on, the economizer damper is open and the power exhaust fans are off. This mode is started by the Fire Pressurization (PRES) input which can be found in the INPUT---)FIRE sub-menu. HVAC ModeEVACUATION (21) -- The unit is in the special Fire Evacuation mode where the supply fan is off, the economizer damper is closed and the power exhaust fans are on. This mode is started by the Fire Evacuation (EVA() input which can be found in the INPUT---_FIRE sub-menu. REMOTE SWITCH CONFIG (RM.CF) -- The remote switch input is connected to TB6 terminals 1 and 3. This switch can be used for several remote control functions. Please refer to the Remote Control Switch Input section for details on its use and operation. HVAC Mode -- SMOKE PURGE (22) -- The unit is in the special Fire Purge mode where the supply fan is on, the economizer damper is open and the power exhaust fans are on. This mode is started by the Fire Evacuation (PURG) input which can be found in the INPUT---_FIRE sub-menu. CEM MODEL INSTALLED (CEM) -- This configuration instructs the control to co_rnnunicate with the controls expansion module (CEM) over the Local Equipment Network (LEN) when set to Yes. When the unit is configured for certain sensors and configurations, this option will be set to Yes automatically. HVAC Mode -- DEHUMIDIFICATION (23) -- The unit is operating in Dehumidification mode. HVAC ModeREHEAT (24) -- The unit is operating in reheat mode. The sensors this board are: Unit Configuration Submenu E The UNIT submenu under the Configuration mode of the local display contains general unit configuration items. The sub-menu which contains these configurations is located at the local display under Configuration--+UNIT. See Table 43. Machine Control Type (C TYP) -- This configuration defines the control type and control source responsible for selecting a cooling, heating, or vent mode and in determining the method by which compressors are staged. The control types are: and configurations that automatically 1 (Supply turn on Configuration--cUNIT-+SFS.M Switch Monitoring) = Fan Stares Configuration-+EDT.R-+RES.S ply Air Reset Sensor Enable) = Enable (4 to 20 mA Sup- Configuration--+DMD.L -+DM.L.S = 1 (2 (Demand Limiting using 2 discrete switches) SWITCHES) Configuration-+DMD.L--cDM.LS = 2 (4-20 (Demand Limiting using a 4 to 20 mA sensor) MA (bnfiguration--)IAQ--)AQ.CF-clQ.LC= (IAQ discrete switch control) CTRL) 1 (IAQ DISCRETE) (bnfiguration--clAQ---)AQ.

If the control is occupied, the supply fan is run continuously and return-air temperature will be used in the determination of the selection of a cooling mode. VAV-SPT differs from VAV-RAT only in that during the unoccupied period, space temperature will be used instead of return-air temperature to start the fan for 10 minutes to establish an (bnfiguration--clAQ--cAQ.(T_OQ.A.C DAQ) (Outdoor Air Quality Sensor) (bnfiguration--clAQ--cAQ.(T_OQ.A.C DAQ) (4 to 20 mA sensor, no DAQ) = 1 (OAQ = 2 SENS- (4-20 NO Temperature Compensated Start Cooling Factor (TCS.() -This factor is used in the equation of the Temperature Compensated Start Time Bias for cooling. Refer to the Temperature 35 Compensated Startsection formoreinformation. A setting 0 minutes indicates Temperature is not permitted. Compensated of Start in Cooling Suction Pressure Transducer Type (SRXR) -- This configuration specifies the type of suction pressure transducer that is being used. Set SRXR to 0 for support of a pressure transducer with a range of 0 to 135 psig. Set SRXR to 1 for support of a pressure transducer with a range of 0 to 200 psig. Temperature Compensated Start Heating Factor (T(_.H) -This factor is used in the equation of the Temperature Compensated Start Time Bias for heating. Refer to the Temperature Compensated Start section for more information. A setting of 0 minutes indicates Temperature Compensated Start in Heating is not permitted. NOTE: The 48/50A2,A3,A4,A5 units do not require a change to the SRXR factory default setting. Refrigerant Type (RFG 7") -- This configuration type of refrigerant used in the unit. Configuration to 0 if the refrigerant used is R-22. Configuration to 1 if the refrigerant used is R-410A. Do not setting. Fan Fail Shuts Downs Unit (SFS.S) -- This configuration will determine whether the unit should shut down on a supply fan status fail or simply alert the condition and continue to run. If set to YES, then the control will shut down the unit and send out an alarm if supply fan status monitoring fails. If set to NO, the control will not shut down the unit if supply fan status monitoring fails but the control will send out an alert. Fan Status Monitoring (SFS.M) -- This configuration the type of fan status monitoring to be performed. Condenser Type (CND./3 -- This configuration specifies the type of condenser installed in the unit. Configuration CND. T is set to 0 if the condenser is a round tube, plate fin coil (RTPF). Configuration CND. T is set to 1 if the condenser is a microchannel heat exchanger coil (MCHX). selects MAT Calc Config (MAI:S) -- This configuration gives the user three options in the processing of the mixed-air temperature (MAT) calculation: • MAT.S = 0 0 - NONE -- No switch or monitoring 1 - SWITCH --Use of the fan status switch 2 - SP RISE -- Monitoring specifies the RFG T is set RFG T is set change this of the supply duct pressure. There will be no MAT calculation. VAV Unoccupied Fan Retry Time (VAES) -- Machine control types 1 and 2 (VAV-RAT, VAV-SPT) monitor the return-air temperature during unoccupied periods to determine if there is a valid demand for heating or cooling before initiating an unoccupied heating or cooling mode. If the routine runs but concludes a valid demand condition does not exist, then the process is not permitted for the period of time defined by this configuration. Reducing this value allows a more frequent resampling process. Setting this value to zero will prevent any sampling sequence. • MA_S=I The control will attempt to learn MAT over time. Any time the system is in a vent mode and the economizer stays at a particular position for long enough, MAT is set to equal EDT. Using this, the control has an internal table whereby it can more closely determine the true MAT value. MAT.S = 2 The control will not attempt to learn MAT over time. To calculate MAT linearly, the user should reset the MAT table entries by setting MAT.R to YES. Then set MAT.S = 2. The control will calculate MAT based on the position of the economizer, outside-air temperature, and return-air temperature. Unit Size (SIZE) -- There are several unit sizes (tons) for the A Series control. Make sure this configuration matches the size called out by the model number of the unit. This is important as the cooling stage tables are directly determined based on this configuration. Discharge Pressure Transducers (DRXR)-This configuration configures the unit for use with discharge pressure transducers. The 48/50A2,A3,A4,A5 units will be automatically configured for discharge pressure transducers and DRXR should be set to Yes. To freeze the MAT table entries, let the unit run withMAr.S = 1. Once sufficient data has been collected, change MAT.S = 2. Do not reset the MAT table. Table 43 -- Unit Configuration ITEM UNIT C.TYP CVFN RM.CF CEM TCS.C TCS.H SFS.S SFS.M VAVS SIZE DP.XR SP.XR RFG.

(MAT.R) -- This configuration allows the user to reset the internally stored MAT learned configuration data back to the default values. The defaults are set to a linear relationship between the economizer damper position and OAT and RAT in the calculation of MAT. mechanical cooling to allow for the greatest use of flee cooling. When both mechanical cooling and the economizer are being used, the control will use the economizer to provide better temperature control and limit the cycling of the compressors. The control also checks on various other operation parameters in the unit to make sure that safeties are not exceeded and the compressors are reliably operated. MAT Outside Air Position Default (MAT.D) -- This configuration is used to calculate MAT when the economizer option is disabled. The configuration is adjustable from 0 to 100% outside air. This defines the fixed ventilation position that will be used to correctly calculate MAT. The A Series (_mforlLink TM control system offers two basic control approaches to mechanical cooling. Constant volume operation for 2 stages of cooling or VAV operation for multiple stages of cooling. In addition to these methods of control, the A Series (_,_fortLink control offers the ability to mn multiple stages of cooling for either a space temperature sensor or thermostat by. controlling the unit to either a low or high cool supply air set point. The control type Configuration --gUNIT_: TYP) determines the selection of the type of cooling control as well as the method for selecting a cooling mode. Altitude ........ In Feet: (ALTI) -- The control does not include a barometric pressure sensor to determine altitude. The altitude must be defined the calculation of enthalpy and cfm. The altitude parameter is used to set up a default barometric pressure for use with calculations. The effect of barometric pressure in these calculations is not great, but could have an effect depending on the installed elevation of the unit. If the unit is installed at a particularly high altitude and enthalpy or cfm are being calculated, set this configuration to the current elevation. There are either three or four compressors divided among two refrigeration circuits in the unit. Circuit A always contains two compressors (A1,A2). Circuit B has either one or two compressors (B1,B2). There may be a minhnum load valve (MLV), which, if present, is only associated with circuit A. The decision as to which compressor should be turned on or off is decided by the compressor's availability followed by a preferred staging order. Start Up Delay Time (DLAY) -- This option delays the unit from operating after a power reset. The configuration may be adjusted from 0 to 900 seconds of delay. TSTAT -- Both Heat and Cool (STAT) -- This option, if enabled, allows both heating and cooling requests to be made at the same thne. If the unit is configured for staged gas heat, and ifa cooling request is initiated (Y1 or Y2), then Wl initiates reheat and W2 initiates dehumidification. NOTE: Configuration of the machine control type (CTYP) has no effect on whether a unit has a VFD or just a supply fan installed for static pressure control. No matter what the control type is, it is possible to mn the unit in either CV or VAV mode provided there are enough stages to accolrunodate lower air volumes for VAV operation. Refer to the section on static pressure control for information on how to set up the unit for the type of supply fan control desired. SETTING UP THE SYSTEM Auxiliary Relay Configuration (AUX.R) -- This option configures the auxiliary relay on the MBB (RLYll). The function of this relay is configurable in the following ways: • • • • AUX.R = 0 (Alarm Output) -- The relay is used for remote annunciation of an alarm state. AUX.R = 1 (Dehum-Reheat) -- The relay is used as a dehumidification!reheat output. AUX.R = 2 (Occup. State) -- The relay is used to reflect occupancy. When the control is in occupied mode, the relay will be ON. When the control is in unoccupied mode, the relay will be OFE AUX.R = 3 (S. Fan State) -- The relay is used to reflect the supply fan colmnanded state. When the supply fan is on, the relay will be ON. When the supply fan is off, the relay will be OFF. Space Temp Sensor (SPT.S) is installed, this configuration -- If a space temperature should be enabled. Machine Control Type (Configuration --+UNIT _C. TYP) -The most important cooling control configuration is located under Configuration --+UNIT. This configuration defines the method and control source responsible for selecting a cooling mode. The configuration also determines the method by which compressors are staged. Control types are: • C. TYP = 1 (VAV-RAT) and C TYP = 2 (VAV-SPT) Both of these configurations refer to standard VAV operation. If the control is occupied, the supply fan is mn continuously and return-air temperature will be used for both in the determination of the selection of a cooling mode. VAV-SPT differs from VAV-RAT only in that during the unoccupied period, space temperature will be used instead of return-air temperature to start the fan for ten minutes before the return-air temperature is allowed to call out any mode. sensor Space Temp Offset Sensor (SRO.S) -- If a space temperarare sensor with a space temperature offset slider is installed (T56), this configuration should be enabled. Space Temp Offset Range (SRO.R) -- If a space temperarare offset sensor is installed, it is possible to configure the range of the slider by adjusting this range configuration. • Return RH Sensor (RRH.S) -- If a return air relative humidity sensor is installed, this configuration should be enabled. C TYP = 3 (TSTAT-MULTI) This configuration will force the control to monitor the the> mostat inputs to make a determination of mode. Unlike traditional 2-stage thermostat control, the unit is allowed to use multiple stages of cooling control and perform VAV style operation. The control will be able to call out a LOW COOL or a HIGH COOL mode and maintain a low or high cool supply air set point. Filter Status Switch Enabled? (FLT.S) -- If a filter stares switch is installed, enable this configuration to begin the monitoring of the filter stares input (Inputs_GEN.I-+FLT.S). See the Dirty Filter Switch section for more details on installation and operation. • COOling COntrOl -- When mechanical cooling is required, the A Series (_,fortLink TM control system has the capability to control the staging of the compressors in several different ways. Three scroll compressors are used on sizes 020 to 027 and four on sizes 030 to 060. In addition, the (_,fortLink control system supports the use of an optional minimum load hot gas bypass valve (MLV) that is directly controlled by the (_,fortLink control system. This provides an additional stage of capacity as well as low load coil freeze protection. The control also integrates the use of an economizer with the use of C TYP = 4 (TSTAT-2 STG) This configuration will force the control to monitor the the> mostat inputs to make a determination of mode. • C. TYP = 5 (SPT-MULTI) This configuration will force the control to monitor a space temperature sensor to make a determination of mode. Unlike traditional 2-stage space temperature control, the unit is allowed to use multiple stages of cooling control and perform VAV style operation. The control will be able to call 37 out a LOW COOL or a HIGH COOL mode and maintain a low or high cool supply air set point. • C. TYP = 6 (SPT-2 STG) This configuration will force the control to monitor the space temperature sensor to make a determination of mode and allow two stages of cooling. MACHINE DEPENDENT CONFIGURATIONS -- Some configurations are linked to the physical unit and must not be SUPPLY AIR RESET CONFIGURATION -- Supply Air Reset can be used to modify the current cooling supply air set point. Supply Air Reset is applicable to control types, C TYP = 1,2,3, and 5. The configurations for reset can be found at the local display under Configuration--gEDT.R. See Table 46. EDT Reset Configuration (RS. CF) -- This configuration applies to several machine control types (Configuration--9 UNIT_: TYP 1,2,3, and 5). 0 = NO RESET changed. The configurations are provided in case a field replacement of a board occurs and the settings are not preserved by the download process of the new software. The following configurations apply to all machine control types (C. TYP) except 4 and 6. These configurations are located at the local display under Configuration --+UNIT. See Table 44. No supply air reset is in effect 1 = SPT RESET Space temperature will be used as the reset control variable along with both RTIO and LIMT in the calculation of the final amount of reset to be applied (Inputs-+RSET -+SA.S.R). 2 = RAT RESET Table 44 -- Machine Dependent Configurations ,T IO UNIT I DEFAULTS Return-air temperature will be used as the reset control variable along with both RTIO and LIMT in the calculation of the final amount of reset to be applied (Inputs-+RSET--€ SA.S.R). 3 = 3RD PARTY RESET [UNIT CONFIGURATION RFG.T [REFRIG 10-1 SIZE [OnitSize(20-60)[20-60 CND.T ICND HX TYP [0-1 *Dependent IREFRIGT IUNITSIZE ICOILTYPE [ The reset value is determined by a 4 to 20 mA third party input. An input of 4 mA would correspond to 0° F reset. An input of 20 mA would correspond to 20 ° F reset. Configuring the control for this option will cause RES.S to become enabled automatically with the CEM board. To avoid alarms make sure the CEM board and third party input are connected first before enabling this option. on unit, Unit Size (SIZE) -- There are several unit sizes (tons) for the A Series control. Make sure this configuration matches the size called out by the model number of the unit. This is important as the cooling stage tables are directly determined based on this configuration. Reset Ratio (RTIO) -- This configuration is used when RS.CF is set to 1 or 2. For every degree that the controlling temperature (space/return) falls below the occupied cooling set point (OCSP), the calculated value of the supply air reset will rise by the number of degrees as specified by this parameter. Reset Limit (LIMT) -- This configuration is used when RS. CF is set to 1 or 2. This configuration places a clamp on the amount of supply air reset that can be applied. EDT 4-20 mA Reset Input (RES.S) -- This configuration is automatically enabled when _bnfiguration--+EDT.R--+ RS. CF is set to 3 (third party reset). COOLING CONFIGURATION-- Relevant configurations for mechanical cooling are located at the local display under Configuration _,COOL. See Table 47. Refrigerant Type (RFG T) -- This configuration specifies the type of refrigerant used in the unit. Configuration RFG T is set to 0 if the refrigerant used is R-22. Configuration RFG T is set to 1 if the refrigerant used is R-410A. Make sure this configuration matches the refrigerant called out by the model number of the unit. Condenser Type ((_WD.

The configuration affects the cycling rate of the cooling stages by raising or lowering the threshold that demand must rise above in order to add or subtract a stage of cooling. CSB A2 Feedback Alarm (CS.A2) -- This configuration is used to enable or disable the compressor A2 feedback alarm. This configuration must be enabled at all times. Normally this configuration should not require any tuning or adjustment. If there is an application where the unit may be significantly oversized and there are indications of high compressor cycles, then the Capacity Threshold Adjust (Z. GN) can be used to adjust the overall logic gain. Normally this is set to 1.0, but it can be adjusted from 0.5 to 4.0. As the value of Z.GN is increased, the cycling of cooling stages will be slowed. CSB B2 Feedback Alarm (CS.B2) -- This configuration is used to enable or disable the compressor B2 feedback alarm. This configuration must be enabled at all times. CSB B1 Feedback Alarm (CS.B1) -- This configuration is used to enable or disable the compressor B1 feedback alarm. This configuration must be enabled at all times. Reverse Rotation Verified? (REV.R) -- If this configuration is set to NO, then after a power up, in the normal run mode, the control will check the suction pressure on the first circuit that is energized after 5 seconds of run time. If the control does not see a sufficient decrease in suction pressure over the first 5 seconds, mechanical cooling will be shut down, and an alarm will be generated (A140). This alarm requires a manual reset. Compressor Lockout Temperature (MCLO) -- This configuration is the outdoor air temperature setting below which mechanical cooling is locked out. Fan-OffDelay, Mech Cool ((AFOD) -- After a mechanical cooling cycle has ended, this is the delay in seconds that the supply fan will continue to operate. If the unit is in the Service performed any time a compressor Once it has been verified that power to the rooftop and compressors has been applied correctly and the compressors start up normally, this configuration can be set to YES in order to prevent the reverse rotation check from occumng. Min. Load Valve (HGBP)? (MLV) -- This configuration instructs the control as to whether a minfinum load valve has been installed and will be controlled by the compressor staging routine. High SST Alert Delay Time (H.SST) -- This option allows the high saturated suction temperature alert tflning delay to be adjusted. COMPRESSOR SAFETIES -- The 48/50A Series units with Col_fortLink TM controls include a compressor protection board (CSB) that protects the operation of each of the compressors. These boards sense the presence or absence of current to each compressor. If there is a colrnnand for a compressor to run and there is no current, then one of the following safeties or conditions have turned the compressor off: MotorMaster Control? (M.M.) -- The condenser fan staging control for the unit is managed directly by the (_nfortLink TM controls. There is no physical Motormaster :R:device in the standard unit. The standard unit is capable of mechanical cooling operation down to 32 F outdoor temperature. With the addition of accessory Motormaster V speed control on the stage 1 condenser fan(s), mechanical cooling operation down to -20 F outdoor temperature is possible. The accessory Motormaster V speed control is a completely self-contained device and is not managed by the unit's (_l_fortLink controller. The Motormaster control configuration (M.M.) only applies to the 060 size RTPF units. On 060 size RTPF units with accessory Motormaster V speed control installed, this configuration must be set to YES. See Head Pressure Control section, page 49, for more inforlnation. • Compressor overcurrent -- Smaller compressors have internal line breaks and larger compressors have a dedicated circuit breaker for overcurrent protection. • Compressor short circuit -- the compressor circuit breaker that provides short circuit protection has tripped then there will not be current. • Compressor motor over temperature -- the internal linebreak or over temperature switch has opened. • High-pressure switch trip -- High-pressure switch has opened. Alarms will also occur if the current sensor board malfunctions or is not properly connected to its assigned digital input. If the compressor is colmnanded OFF and the Current Sensor reads ON, an alert is generated. This will indicate that a compressor contactor has failed closed. In this case, a special mode "Compressor Stuck on Control" will be enabled and all other compressors will be turned offand an alarm enabled to indicate that service is required. Indoor and outdoor fans will continue to operate. The first outdoor fan stage is turned on igunediately.

COMPRESSOR TIME GUARDS -- The control will not allow any output relay to come on within 3 seconds of any other output relay. For outputs connected to the compressors, the control will use a Compressor Minimum OFF Thne of 2 minutes, a Compressor Minhnum ON Thne of 3 minutes and a Minhnum Delay before turning on another compressor of 10 seconds. COOL MODE SELECTION PROCESS -- The A Series (_nfortLink TM controls offer three distinct methods by which it may select a cooling mode. 1. Thermostat (4:TYP=-3 and 4): The thermostat does not depend upon the state of occupancy and the modes are called out directly by the discrete inputs from the thermostat (Inputs-cSTAT-cY1 and Y2). 2. Occupied VAV cooling types ((: TYP=-I and 2) are called out in the occupied period (Operating Modes--€ MODE-+ OCC=ON). 3. Unoccupied VAV cooling types (4:TYP=-I and 2) are called out in the unoccupied period (Operating Modes--€ MODE--cOCC=OFF). They are also used for space sensor control types (4:TYP=-5 and 6) in both the occupied and unoccupied periods. This section is devoted to the process of cooling determination for the three types outlined above. VAV Cool Mode Selection during the Occupied Period (4: TYP = 1,2 and Operating Modes-cMODE _OCC =ON) -- There is no difference in the selection of a cooling mode for either VAV-RAT or VAV-SPT in the occupied period. The actual selection of a cool mode, for both control types, is based upon the controlling return-air temperature (Temperatures-+AIR. T _TRL-+R.TMP). Typically this is the same as the return air temperature thermistor (Temperatures---)AIR. T---_RAI) except when under CCN Linkage. VAV Occupied (_ol Mode Evaluation (_nfiguration are VAV occupied cooling offsets under Seq_oints.

See Fig. 7. The occupied cooling set point is not used in the determination of the cool mode. The occupied cooling set point is used for supply air reset only. .___. 80 _g EXPANSION VAV Occ. Cool On Delta VAV Occ. Cool Off Delta -- There (_ol Mode Determination -- If the machine control type (Configuration--€ UNIT_: TYP) = 1 (VAV-RAT) or 2 (VAVSPT) and the control is occupied (Operating Modes -+MODE-cOCC=ON), then the unit will not follow the occupied cooling set point (OCSP). Instead, the control will follow two offsets in the determination of an occupied VAV cooling mode (Setpoints -+V..C.ON and Setpoints--cV.. C OF), applying them to the low-heat offtrip point and comparing the resulting temperature to the return-air temperature. Fig. 5 -- Advanced Scroll Temperature Protection Label 120 110 mode 80 90 (Minutes) m m *Times are approximate. NOTE: Various factors, including high humidity, high ambient temperature, and the presence of a sound blanket will increase cooldown times. OHSP _ Fig. 6 -- Recommended Minimum Cool-Down Time After Compressor is Stopped* _ Fig. 7 -- VAV Occupied 4O V.C. ON Period IV.C. Trip Logic OF The advantage of this offset technique is that the control can safely enforce a vent mode without worrying about crossing set points. Even more importantly, under CCN linkage, the occupied heating set point may drift up and down and this method ensures a guaranteed separation in degrees Fahrenheit between the calling out of a heating or cooling mode at all times. or is in the temperature compensated start mode (T.CST). If the unit is occupied or in temperature compensated start mode, the occupied cooling set point (OCSP) is used. For all other modes, the unoccupied cooling set point (UCSP) is used. For further discussion and simplification this will be referred to as the "cooling set point." See Fig. 8. Demand Level Low (_ol ()n ()ff;'et (L.CON) -- This is the cooling set point offset added to the cooling set point at which point a Low Cool mode starts. NOTE: There is a sub-menu at the local display (Run Status --+TRIP) that allows the user to see the exact trip points for both the heating and cooling modes without having to calculate them. Refer to the Cooling Mode Diagnostic Help section on page 46 for more information. Demand Level High (_ol On Off;'et (H.CON) -- This is the cooling set point offset added to the "cooling set point plus L.CON" at which point a High Cool mode begins. To enter into a VAV Occupied Cool mode, the controlling temperature must rise above [OHSP minus L.H.ON plus L.H.OF plus V.C ONJ. Demand Level Low (_ol Off Off;'et (L.C.OF) -- This is the cooling set point offset subtracted from "cooling set point plus L.CON" at which point a Low Cool mode ends. To exit out of a VAV Occupied Cool Mode, the controlling temperature must fall below [OHSP minus L.H.ON plus L.H.OFplus V.CONminus V.COF]. NOTE: The "high cool end" trip point uses the "low cool off' (L.C.OF) offset divided by 2. NOTE: With vent mode, it is possible to exit out mode during the occupied period if the return-air drops low enough. When supply-air temperature configured, this capability will work to prevent the space during the occupied period. To enter into a LOW COOL mode, the controlling temperature must rise above the cooling set point plus L.CON. of a cooling temperature reset is not over-cooling To enter into a HIGH COOL mode, the controlling temperature must rise above the cooling set point plus L.C.ON plus H.CON. ,5'z_ply Air bet Point (_ntlvl and the Staging of (_mpressom -- Once the control has determined that a cooling mode is in effect, the cooling control point (Run Status--+VIEW _(Z.C.P) is calculated and is based upon the supply air set point (Setpoints-+SASP) plus any supply air reset being applied (Inputs--_RSET--_SA.S.R). To exit out of a LOW COOL mode, the controlling temperature must fall below the cooling set point plus L. CON minus L.COF. Refer to the SumZ Cooling Algorithm section on page 46 for a discussion of how the A Series (_nfortLink TM controls manage the staging of compressors to maintain supply-air temperature. (_nfort Trending -- In addition to the set points and offsets which determine the trip points for bringing on and bringing off cool modes, there are 2 configurations which work to hold off the transitioning from a low cool to a high cool mode if the space is cooling down quickly enough. This method is referred to as Comfort Trending. The comfort trending configurations are C T.LV and C T. TM. To exit out of a HIGH COOL mode, the controlling temperature must fall below the cooling set point plus L. CON minus L. C OF/2. VAV Cool Mode Selection during the Unoccupied Period (C.TYP = 1,2; Operating Modes--_MODE_OCC=OFF) and Space Sensor Cool Mode Selection (4:TYP=-5 and 6) -The machine control types that use this type of mode selection are: • • • • C TYP = 1 (VAV-RAT) in the unoccupied period C.TYP = 2 (VAV-SPT) in the unoccupied period C.TYP = 5 (SPT-MULTI) in both the occupied unoccupied period C TYP = 6 (SPT-2 STG) in both the occupied unoccupied period (_ol Trend Demand Level (CT.LV) -- This is the change in demand that must occur within the time period specified by C.T.TM in order to hold off a HIGH COOL mode regardless of demand. This is not applicable to VAV control types (C TYP=-I and 2) in the occupied period. As long as a LOW COOL mode is making progress in cooling the space, the control will hold off on the HIGH COOL mode. This is especially true for the space sensor machine control types (C TYP = 5 and 6), because they may transition into the occupied mode and see an ilrnnediate large cooling demand when the set points change. and and These particular control types operate differently than the VAV types in the occupied mode in that there is both a LOW COOL and a HIGH COOL mode. For both of these modes, the control offers two independent set points, Seq_oints-+SA.LO (for LOW COOL mode) and Setpoints--_SA.HI (for HIGH COOL mode). The occupied and unoccupied cooling set points can be found under Setpoints. ITEM EXPANSION RANGE UNITS CCN POINT (_ol Trend Time (CT.TM) -- This is the time period upon which the cool trend demand level (CT.LV) operates and may hold offstaging or a HIGH COOL mode.

Circuit A always contains two compressors (Outputs_COOL-cA1 and A2). Circuit B has either one compressor (Outputs_,COOL-+B1) on size 020-027 units or two compressors (Outputs_COOL-cB1 and B2) on size 030-060 units. For 2-stage cooling control, regardless of configuration, there is no mmhnum load valve (MLV) control. The decision as to which compressor should be mined on or offnext is decided by the compressor's availability and the preferred staging order. mode. Sz_ply Air Set Point (_ntrol -- Once the control has determined that a cooling mode is in effect, the cooling control point (Run Status-+VIEW_(Z.C.P) is calculated and is based upon either Setpoints-cSA.HI or Setpoints-cSA.LO, depending on whether a high or a low cooling mode is in effect, respectively. In addition, if supply air reset is configured, it will also be added to the cooling control point. Either A1 or A2 may start first as there is a built-in lead/lag logic on compressors A1 and A2 every time the unit stages to 0 compressors. Also, based on compressor availability, it should be noted that any compressor may come on. For example, on a 3 compressor unit, if no compressors are currently on, compressor A2 is currently under a minimum off compressor timeguard, and 2 compressors are to be turned on, then compressors A1 and B1 will be turned on hmnediately instead of A1 and A2. Refer to the SumZ Cooling Algorithm section for a discussion of how the A Series (_n_fortLink TM controls manage supply-air temperature and the staging of compressors for these control types. Thermostat Cool Mode Selection ((2: TYP = 3 and 4) -When a thermostat type is selected, the decision making process involved in determining the mode is straightforward. Upon energizing the Y1 input only, the unit HVAC mode will be LOW COOL. Upon the energizing of both Y1 and Y2 inputs, the unit HVAC mode will be HIGH COOL. If just input G is energized the unit HVAC mode will be VENT and the supply fan will run. Selecting the C TYP = 3 (TSTAT - MULTI) will cause the control to do the following: 1 -1 -2 0.5 - 20.0 0.5- 2 -1 -2 0.5 - 20.0 0.5- 2 0.1 -5 0.1 -5 30 - 600 30 - 600 Low (_ol Vels'us High (_ol Mechanical Staging The number of compressors to be requested during a cooling mode are divided into 2 groups by the control, HVAC mode = Lo Cool and HVAC mode = Hi Cool. If the economizer is not able to provide free cooling (Run Status-+ECON--+ACTV = NO) then the following staging control type occurs • Lo Cool Mode mechanical • Hi Cool Mode mechanical size units) • Hi Cool Mode mechanical size units) • The control will read the Configuration-+UNIT--+SIZE configuration parameter to determine the number of cooling stages and the pattern for each stage. • An HVAC mode equal to LOW COOL will cause the unit to select the Setpoints-cSA.LO set point to control to. An HVAC mode equal to HIGH COOL will cause the unit to select the Setpoints-cSA.HI set point to control to. Supply air reset (if configured) will be added to either the low or high cool set point. • The control will utilize the SumZ cooling algoritlnn and control cooling to a supply air set point. See the section for the SumZ Cooling Algorithm section for information on controlling to a supply air set point and compressor staging. If the economizer tus--+ECON---)ACTV stages = 2 stages = 3 (for 020 through 027 stages = 4 (for 030 through 060 is able to provide free cooling (Run Sta= YES) then the following staging occurs 1. If the economizer's current position is less than (bnfiguration-cE(DN-cEC.MX5 and mechanical cooling has not yet started for the current cool mode session then: 2. Selecting the C TYP = 4 (TSTAT - 2 STG) control type means that only two stages of cooling will be used. On unit sizes 020, 025 and 027 (with three compressors), an HVAC Mode of LOW COOL will energize one compressor in Circuit A; an HVAC Mode of HIGH COOL will energize all three compressors. On unit sizes 030 and larger (with four compressors) an HVAC Mode of LOW COOL will energize both compressors in Circuit A; an HVAC Mode of HIGH COOL will energize all four compressors. Refer to the section on Economizer Integration with Mechanical Cooling for more information. 3. 2-Stage Cooling Control Logic ((: TYP = 4 and 6) -- The logic that stages mechanical cooling for the TSTAT and SPT 2-Stage cooling control types differs from that of the multistage control types. This section will explain how compressors 4. 42 Lo Cool Mode mechanical stages = 0 Hi Cool Mode mechanical stages = 0 During the first 2.5 minutes of a low or high cool mode where the economizer position is greater than (bnfiguration --¢E(DN-cEC.MX5% and mechanical cooling has not yet started: Lo Cool Mode mechanical stages = 0 Hi Cool Mode mechanical stages = 0 If the economizer position is greater than (bnfiguration --+ECON--+EC.MX5% for more than 2.5 minutes but less than 5.5 minutes and mechanical cooling has not yet started then: Lo Cool Mode mechanical stages = 1 Hi Cool Mode mechanical stages = 1 If the economizer position is greater than (bnfiguration --+ECON--)ECMX5% for more than 5.5 minutes but less than 8 minutes and mechanical cooling has started then Lo Cool Mode mechanical Mode mechanical stages = 2. 5. 6. stages = 2 and Hi Cool If the set point cannot be satisfied or the economizer is not active, then cooling will be brought on one stage at a time when the evaporator discharge temperature (EDT) is greater the 1.5 ° F above the current cooling control point. A start-up time delay of 10 minutes and steady state delay after a compressor is energized of 5 minutes is enforced. If the economizer position is greater than (bnfiguration -+ECON-+ECMX5% for more than 8 minutes but less than 11.5 minutes and mechanical cooling has started then: Lo Cool Mode mechanical stages = 2 Hi Cool Mode mechanical stages = 3 If both circuits of mechanical cooling are running, then the economizer will attempt to control to 48 E If the economizer is active and the outside-air temperature (OAT) is less than the cooling control point + 0.5 F, the compressors will be locked off. When mechanical cooling is on, the control may also use the economizer to trim the leaving-air temperature to prevent unnecessary cycles of the compressor stages. If the economizer position is greater than (bnfiguration -sECON-sEC.MX5% for more than 11.5 minutes and mechanical cooling has started then: Lo Cool Mode mechanical stages = 2 Hi Cool Mode units only) mechanical stages = 3 (for 020 to 027 Hi Cool Mode units only) mechanical stages = 4 (for 030 to 060 See the Economizer Integration with Mechanical Cooling section for more information on the holding off of mechanical cooling as well as the economizer control point. Table 49 -- 2-Stage Sequence -48/50AJ,AW020-027 NOTE: If some compressors are not available due to being faulted, the Hi Cool Mode number of compressors are affected before the Lo Cool Mode number of compressors. For example, if a 4 compressor unit has one compressor faulted, and the economizer is not active, then an HVAC mode Hi Cool requested number of compressors is changed from 4 to 3. If another compressor faults, then both Lo Cool and Hi Cool requested number of compressors are set to 2. In addition, compressors cannot be brought on faster than one every 30 seconds. If the control needs to bring on 2 compressors at once, the first compressor will come on followed by the second compressor 30 seconds later. Staging of compressors is shown in Tables 49-60.

SUMZ COOL1NG ALGORITHM -- The SumZ cooling algoritlnn is an adaptive PID which is used by the control whenever more than 2 stages of cooling are present (C TYP = 1,2,3, and 5). This section will describe its operation and define its parameters. It is generally not necessary to modify parameters in this section. The information is presented prhnarily for reference and may be helpful for troubleshooting complex operational problems.

The controlling temperature is "TEMP" and is in the middle of the table for easy reference. The HVAC mode can also be viewed at the bottom of the table. ITEM = R.PCT Low Temp Cap Override (L. TMP) -- If the error is less than twice Y.MIN, and the rate of change of error is less than -0.5 ° F per minute, then a mechanical stage will be removed every 30 seconds. This override is intended to quickly react to situations where the load is rapidly reduced. represents Pull Down Cap Override (PULL) -- If the error from set point is above 4 ° F, and the rate of change is less than -1 ° F per minute, then pulldown is in effect, and "SUM" is set to 0. This keeps mechanical cooling stages from being added when the error is very large, but there is no load in the space. Pulldown for units is expected to rarely occur, but is included for the rare situation when it is needed. Most likely pulldown will occur when mechanical cooling first becomes available shortly after the control goes into an occupied mode (after a warm unoccupied mode). -- If demand lhnit is active, amount of capacity that the Capacity Load Factor (SMZ) -- This factor builds up or down over time (-100 to +100) and is used as the means of adding or subtracting a cooling stage during mn time.

For a unit with 4 stages, each stage represents about 7.5 ° F of change to EDT. If stages could reliably be cycled at very fast rates, the set point could be maintained very precisely. Since it is not desirable to cycle compressors more than 6 cycles per hour, slow change ovemde takes care of keeping the PID under control when "relatively" close to set point. 2) the amount addition of expected rise for the next cooling stage 3) the amount subtraction of expected rise for the next cooling stage SumZ Operation -- The SumZ algorithin is an adaptive PID style of control. The PID is progralmned within the control and the relative speed of staging can only be influenced by the user through the adjustment of the Z GN configuration. The capacity control algorithin uses a modified PID algorithin, with a self adjusting gain which compensates for varying conditions, including changing flow rates across the evaporator coil. Z.PLU= The calculation of"Z" requires two variables, ZPL U used when adding a stage and Z.MINused when subtracting a stage. They are calculated with the following formulas: * 0.6 * 0.6 Z.GN = configuration used to modify the threshold for staging ( Configuration-gC OOL -gZ GN) ADD.R stage) Previous hnplementations of SumZ made static assumptions about the actual size of the next capacity jump up or down. This control uses a "rise per percent capacity" technique in the calculation of SumZ, instead of the previous "rise per stage" method. For each jump, up or down in capacity, the control will know beforehand the exact capacity change brought on. Better overall staging control can be realized with this technique. SUM Calculation -- The PID calculation of the "SUM" is evaluated once every 80 seconds. = R.PCT SUB.R = R.PCT ing stage) * (C CAP - capacity * (C CAP- levels used after adding a cooling capacity after subtracting a cool- Both of these terms, Z.PLUand Z.MIN, represent a threshold both positive and negative upon which the "SUM" calculation must build up to in order to cause the compressor to stage up or down. (_mparing SUM and Z -- The "SUM" calculation is compared against ZPL U and Z.MIN. • If"SUM" rises above Z.PLU, a cooling stage is added. • If"SUM" falls belowZ.MIN, a cooling stage is subtracted. There is a variable called SMZ which is described in the reference section and which can shnplify the task of watching the demand build up or down over time. It is calculated as follows: SUM = Error + "SUM last thne through" + (3 * Error Rate) Where: SUM = the PID calculation, Error = EDT - Cooling Control Point, Error Rate = Error- "Error last time through" NOTE: "Error" is limited to between-50 and +50 and "Error rate" is limited to between -20 and +20. This "SUM" in determining subtracted. Z GN * (10 + (4*(-ADD.R))) Z.MIN= Z GN * (-10 + (4*(-SUB.R))) Where: If SUM is positive: SMZ = 100*(SUM!ZPLU) If SUM is negative: SMZ = - 100 * (SUM!ZMIN) will be compared against the "Z" calculations whether cooling stages should be added or Mixed Air Temperature Calculation (MAT) -- The mixedair temperature is calculated and is a function of the economizer position. Additionally there are some calculations in the control which can zero in over time on the relationship of return and outside air as a function of economizer position. There are two configurations which relate to the calculation of "MAT." These configurations can be located at the local display under Configuration -gUNIT. Z Calculation -- For the "Z" calculation, the control attempts to determine the entering and the leaving-air temperature of the evaporator coil and based upon the difference between the two during mechanical cooling, and then determines whether to add or subtract a stage of cooling. This is the adaptive element. The entering-air temperature is referred to as MAT (mixed-air temperature) and the leaving-air temperature of the evaporator coil is referred to as EDT (evaporator discharge temperature). They are found at the local display under the Temperatures _C'TRL sub-menu. The main elements to be calculated and used in the calculation of SumZ are: ITEM EXPANSION RANGE CON POINT I I DEFAULTS I UNIT UNIT CONFIGURATION MAZS MAZR 1) the rise per percent capacity (R.PCT) 47 MAT Calc Config Reset MAT Table Entr es? 0 -2 Yes/No MAT SEL MATRESET Nlo MAT Cale (_nfig (MAT.S) -- This configuration gives the user two options in the processing of the mixed-air temperature (MAT) calculation: • MAT.S = 0 There will be no MAT calculation.

Any time the system is in a vent mode and the economizer stays at a particular position for long enough, MAT = EDT. Using this method, the control has an internal table whereby it can more closely determine the true MAT value. MAT.S = 2 • • The control will not attempt to learn MAT over thne. To calculate MAT linearly, the user should reset the MAT table entries by setting MAT.R to YES. Then set MAT.S = 2. The control will calculate MAT based on the position of the economizer and outside air and return air temperature. To freeze the MAT table entries, let the unit run withMAT.S = 1. Once sufficient data has been collected, change MAT.S = 2. Do not reset the MAT table. • • Reset MAT Table Entries? (MAT.R) -- This configuration allows the user to reset the internally stored MAT learned configuration data back to the default values. The defaults are set to a linear relationship between the economizer damper position and OAT and RAT in the calculation of MAT. SumZ Overrides -- There are a number of overrides to the SumZ algofitlun which may add or subtract stages of cooling. • • • • • Dmd -- Dmd -- Limit Limit Switch I--cDL.S2 The following table illustrates the demand limiting (Run Status_'OOL-+DEM.L) that will be in effect based on the logic of the applied switches: Switch Status Run Status--)COOL--)DEM.L Inputs-->GEN.I-->DL.S1 Inputs-->GEN.I-->DL.S2 = OFF = OFF 100% Inputs-->GEN.I-->DL.Sl= Inputs-->GEN.I-->DL.S2 ON = OFF Configuration--)DMD.L--)D.L.Sl Inputs-->GEN.I-->DL.Sl= Inputs-->GEN.I-->DL.S2 ON = ON Configuration--)DMD.L--)D.L.S2 Inputs-->GEN.I-->DL.Sl= Inputs--)GEN.I--)DL.S2 OFF = ON Configuration--)DMD.L--)D.L.S2 = 1 4-20 mA Demand Limiting (DM.L.S 2) -- If the unit has been configured for 4 to 20 mA demand limiting, then the Inputs--c4-20--cDML.M value is used to determine the amount of demand limiting in effect (Run Status _'OOL--+ DEM.L).

Mechanical Coolin_ Lockout ((bnfiguration _'OOL--€ MCLO) -- This configuration allows a configurable outsideair temperature set point below which mechanical cooling will be completely locked out. DEMAND LIMIT CONTROL -- Demand Lfinit Control may override the cooling algoritlun to limit or reduce cooling capacity during run time. The term Demand Lfinit Control refers to the restriction of machine capacity to control the amount of power that a machine will use. This can save the owner money by limiting peaks in the power supply. Demand limit control is intended to interface with an external Loadshed Device either through CCN colrnnunications, external switches, or 4 to 20 mA input. • This type of Inputs" _GEN.I-+DL.S1 For a long cooling session where the outside-air temperarare may drop over time, there may be a point at which the economizer has closed down far enough were the unit could remove a cooling stage and open up the economizer further to make up the difference. • Two-Switch Demand Limiting (DM.L.S l) -demand limiting utilizes two discrete inputs: The state of the discrete switch inputs can be found at the local display: Economizer Trim Override -- The unit may drop stages of cooling when the economizer is performing free cooling and the configuration Configuration--+ECON--+E.TRM is set to Yes. The economizer controls to the same supply air set point as mechanical cooling does for SumZ when E. TRM = Yes. This allows for much tighter temperature control as well as cutting down on the cycling of compressors. of loadshedding in effect, 0 = NONE -- Demand Limiting not configured. 1 = 2 SWITCHES -- This will enable switch input demand limiting using the switch inputs connected to the CEM board.

Upon reception of a redline cognnand, the machine will be prevented from starting if it is not running. If it is running, then DEM.L is set equal to the current running cooling capacity (Run Status _COOL _C CAP). Upon reception of a loadshed colmnand, the DEM.L variable is set to the current running cooling capacity (Run Status _COOL_(LCAP) minus the configured Loadshed Demand Delta (SH.DL). A redline colmnand or loadshed colmnand will stay in effect until a Cancel redline or Cancel loadshed colmnand is received, or until the configurable Maximum Loadshed time (SH. TM) has elapsed. HEAD PRESSURE CONTROL -- Condenser head pressure control for the 48/50A series rooftops is controlled directly by the unit, except when the unit is equipped and configured for Motormaster(R) V control. The control is able to cycle up to three stages of outdoor fans (see Table 64) to maintain acceptable head pressure. % %. I mm '/o % I CCN POINT I DEFAULT DMT2-OMA SHED NUM DMD CTRL SHED DEL i O0 DLSWSP1 SHED TIM DLSWSP2 80 _ For 020 to 035 size units, there are two outdoor fans that are colrnnon to both refrigerant circuits. The control cycles two stages of outdoor fans, one fan per stage, to maintain acceptable head pressure. For 036 to 050 size units, there are four outdoor fans that are colrnnon to both refrigerant circuits. The control cycles two stages of outdoor fans, two fans per stage, to maintain acceptable head pressure. For 051 and 060 size units - There are six outdoor fans that are colrnnon to both refrigerant circuits (size 060 MCHX units have 4 fans). The control cycles three stages of outdoor fans, two fans for stage one, four fans for stage two, and six fans for stage three to maintain acceptable head pressure. For 48/50AJ,AK,AW, AY units, fan stages will react to samrated condensing temperature (SCT) sensors (Temperatures--+REET--+SCT.A and SCT.B) which are connected to the condenser coils in circuit A and B. The control converts the temperatures to the corresponding refrigerant pressures (Pressures--cREEP -+DRA and DRB). For 48/50A2,A3,A4,A5 units, fan stages react to discharge pressure transducers (DPT) (Pressures--cREEP-+DRA and DRB) which are connected to the compressor discharge piping in circuit A and B. The control converts the pressures to the corresponding saturated condensing temperatures (Temperatures--+REE T--+SCT.A and SCT.B). When a compressor has been colrnnanded on, then condenser fan A (MBB Relay 6) will be energized (CD.EA = ON). Condenser fan A will remain on until all compressors have been cognnanded off. If the highest active circuit SCT is above the HPSP or if OAT is greater than 75 F then condenser fan B (MBB Relay 5) will be energized (CD.EB = ON). Condenser fan B will remain on until all compressors have been colrnnanded off, or the highest active circuit SCT drops 40 F below the HPSP for greater than 2 minutes and OAT is less than 73 E Unit size (Configuration-cUnit-cSize), refrigerant type (Configuration-+Unit-+RFG1), and condenser heat exchanger type (Configuration-+Unit-+(ND. 1) are used to determine if the second stage fans are configured to respond to a particular refrigerant circuit (independent control) or both refrigerant circuits (colmnon control). The 48/50A2,A3, A4,A5060 units with microchannel (MCHX) condenser heat exchangers are the only units that utilize independent fan controls. If the unit is equipped with the accessory control, the Motormaster installed UNITS ((bnfiguration--cCOOL--_M.M.) must be set to YES if the unit size ((bnfiguration--+Unit--cSize) is 60 tons and the condenser heat exchanger type ((bnfiguration--cUnit--cCND.1) is RTPF (round robe plate fin). This is because the condenser fan relay A (MBB Relay 6) output must be energized to enable the Motormaster V control and must not be mined off by the head pressure control algorithin. The size 60 ton unit with RTPF condenser heat exchangers offers 3 stages of head pressure control and is the one case where condenser fan relay A may be requested off during head pressure control operation. By configuring M.M. to YES, the control is instructed not to turn off the relay to attempt 3 stages of head pressure control. There are two configurations provided for head pressure control that can be found at the local display: • (bnfiguration _COOL--_M.M. - Motor Master (bntrol? • (bnfiguration-+COOL--cHPSPHead Pressure Setpoint There are two outputs (MBB Relays) provided to control head pressure: • Outputs-cFANS-cCD.EA - Condenser Fan Circuit A (MBB Relay 6 - OFC1,4).

The cycles two stages of outdoor fans for each circuit, one stage, to maintain acceptable head pressure. contactor B1 or B2 auxiliary contacts drive OFC1. If the economizer is able to provide free cooling at the start of a cooling session, the mechanical cooling algorithin checks the economizer's current position (Run Status--+ ECON-+ECN..P) and compares it to the economizer's maximum position (C'onfiguration--+EC'ON--+EC:MX) - 5%. Once the economizer has opened beyond this point a 2.5-minute timer starts. If the economizer stays beyond this point for 2.5 minutes continuously, the mechanical cooling algofithin is allowed to start computing demand and stage compressors. When a circuit A compressor has been colrnnanded on, then OFC3 is energized via the normally opened auxiliary contacts on the compressor contactors. The auxiliary contacts are wired such that turning on either circuit A compressor will energize OFC3. Contactor OFC3 will remain on until all circuit A compressors have been colrnnanded off. If SCTA is above the HPSP or if OAT is greater than 75 F, then condenser fan A (MBB Relay 6) will be energized (CD.EA = ON) turning on OFC4. Condenser fan A will remain on until all compressors have been conunanded off, or SCTA drops 40 F below the HPSP for greater than 2 minutes and OAT is less than 73 F. Economizer Control Point (Run Status--+VIEW--+EC: C:P) -- There are 4 different ways to determine the economizer control point when the economizer is able to provide free cooling: If no mechanical COOL When a circuit B compressor has been conunanded on, then OFC1 is energized via the normally opened auxiliary contacts on the compressor contactors.

The control turns on the second fan stage when the OAT is above 65 F and stages down when OAT drops below 50 F. suction pressure reset cooling has started = 48 F plus any economizer suction pressure reset Heating Control -- The A Series (_l,fortLink TM control system offers control for 3 different types of heating systems to satisfy general space heating requirements: 2-stage gas heat, 2-stage electric heat and multiple-stage (staged) gas heat. If the OAT sensor fails, then the control defaults to head pressure control based on the SCT sensors. The control turns on the second fan stage when the highest active circuit SCT is above the HPSP and stages down when the highest active circuit SCT drops 40 F below the HPSP for longer than 2 minutes. Variable air volume (VAV) type applications (C TYP = 1, 2, 3, or 5) require that the space terminal positions be colrnnanded to open to Minimum Heating positions when gas or electric heat systems are active, to provide for the unit heating system's Minimum Heating Airflow rate. If the SCT, DPT, and OAT sensors have all failed, then the control turns on the first and second fan stages when any compressor is colrnnanded on. For VAV applications, the heat interlock relay (HIR) function provides the switching of a control signal intended for use by the VAV terminals. This signal must be used to conunand the terminals to open to their Heating Open positions. The HIR is energized whenever the Heating mode is active, an IAQ preoccupied force is active, or if fire smoke modes, pressurization, or smoke purge modes are active. Compressor current sensor boards (CSB) are used on all units and are able to diagnose a compressor stuck on (welded contactor) condition. If the control conunands a compressor off and the CSB detects current flowing to the compressor, then the first fan stage is turned on ilrnnediately. The second fan stage will turn on when OAT rises above 75 F or the highest active circuit SCT rises above the HPSP and remain on until the condition is repaired regardless of the OAT and SCT values. ECONOMIZER INTEGRATION WITH MECHANICAL COOLINGWhen the economizer is able to provide free cooling (Run Status--cECON--cACTV = YES), mechanical cooling may be delayed or even held offindefinitely.

VAV-RAT or VAV-SPT, except that for VAV-SPT, space temperature is used in the unoccupied period to turn on the supply fan for 10 minutes before checking return-air temperature. The actual selection of a heat mode, LOW or HIGH for both control types, will be based upon the controlling return-air temperature. With sufficient heating demand, there are still conditions that will prevent the unit from selecting a heat mode. First, the unit must be configured for a heat type (Configuration--€ HEAT--+HT.(T not equal to "NONE"). Second, the unit has a configuration which can enable or disable heating in the occupied period except for a standard morning warmup cycle ((bnfiguration---_HEAT_OC.EN). See descriptions above in the Setting Up the System section for more information. If the unit is allowed to select a heat mode, then the next step is an evaluation of demand versus set point. At this point, the logic is the sane as for control types SPT Multi-Stage and SPT-2 Stage, (C TYP = 5,6) except for the actual temperature compared against set point. See Temperature Driven Heat Mode Evaluation section. Occupied Heating Enable (OC.EN) -- This configuration only applies when the unit's control type ((bnfiguration -gUNIT_C TYP) is configured for 1 (VAV-RAT) or 2 (VAVSPT). If the user wants to have the capability of performing heating throughout the entire occupied period, then this configuration needs to be set to "YES". Most installations do not require this capability, and if heating is installed, it is used to heat the building in the morning. In this case set OCENto "NO". NOTE: This unit does not support shnultaneous heating and cooling. If significant simultaneous heating and cooling demand is expected, it may be necessary to provide additional heating or cooling equipment and a control system to provide occupants with proper comfort. MBB Sensor Heat Relocate (LAT.M) -- This option allows the user additional performance benefit when under CCN Linkage for the 2-stage electric and gas heating types. As twostage heating types do not "modulate" to a supply air set point, no leaving air thermistor is required and none is provided. The evaporator discharge thermistor, which is initially installed upstrean of the heater, can be repositioned downstrean and the control can expect to sense this heat. While the control does not need this to energize stages of heat, the control can wait for a sufficient temperature rise before announcing a heating mode to a CCN linkage system (ComfortID_M). If the sensor is relocated, the user will capability to view the leaving-air temperature Te mper atu r es --)AIR. T--c( TRL --cLA T.

With thermostat control the Wl and W2 inputs determine whether the HVAC Mode is LOW or HIGH HEAT. now have the at all times at Wl = ON, W2 = OFF: HVAC MODE = LOW HEAT* W2 = ON, W2 = ON: HVAC MODE = HIGH HEAT NOTE: If the user does not relocate this sensor for the 2-stage electric or gas heating types and is under CCN Linkage, then the control will send a heating mode (if present) unconditionally to the linkage coordinator in the CCN zoning system regardless of the leaving-air temperature. *If the heating type is either 2-stage electric or 2-stage gas, the unit may promote a low heat mode to a high heat mode. NOTE: If W2 = ON and Wl is OFF, a "HIGH HEAT" HVAC Mode will be called out but an alert (T422) will be generated. See Alarms and Alerts section on page 93. Fan-Off Delay, Gas Heat (GFOD) -- This configuration is the delay in seconds, after a gas heat mode has ended (HT.CF=2,3) that the control will continue to energize the supply fan. SPT Multi-Stage ((:TYP = 5) and SPT 2 Sta_e ((:TYP = 6) -- There is no difference in the selection of a heat mode between the control types SPT 2-stage or SPT multi-stage. These selections only refer to how cooling will be handled. So, for a valid heating type selected (HT.(T" not equal to zero) the unit is free to select a heating mode based on space temperature (SPT). Fan-Off Delay, Elec Heat (E.FOD) -- This configuration is the delay in seconds, after an electric heat mode has ended (HT.CF=I) that the control will continue to energize the supply fan. HEAT MODE SELECTION PROCESS -- There are two possible heat modes that the control will call out for heating control: HVAC Mode = LOW HEAT and HVAC Mode = HIGH HEAT. These modes will be called out based on control type (C. TYP). If the unit is allowed to select a heat mode, then the next step is an evaluation of demand versus set point. At this point, the logic is the sane as for control types VAV-RAT and VAV-SPT (CTYP = 1,2), except for the actual temperature compared against set point. See Temperature Driven Heat Mode Evaluation section on page 52. VAV-RAT (C. TYP = 1) and VAV-SPT (C TYP = 2) -- There is no difference in the selection of a heating mode for either 51 TEMPERATURE DRIVEN HEAT MODE EVALUATION -This section discusses the control method for selecting a heating mode based on temperature. Regardless of whether the unit is configured for return air or space temperature, the logic is exactly the same. For the rest of this discussion, the temperature in question will be referred to as the "controlling temperature." First, the occupied and unoccupied heating set points under Setpoints must be configured. ITEM EXPANSION OHSP Occupied Setpoint Heat UHSP Unoccupied Heat Setpoint CCN POINT To get out of a HIGH HEAT mode, the controlling temperature must rise above the heating set point minus L.H.ONplus L.H.OF/2. The Run Status table in the local display allows the user to see the exact trip points for both the heating and cooling modes without doing the calculations. Heat Trend Demand Level (tt. T.LV) -- This is the change in demand that must be seen within the time period specified by H. r.rMin order to hold off a HIGH HEAT mode regardless of demand. This is not applicable to VAV control types (C TYP=I and 2) in the occupied period. This method of operation has been referred to as "Comfort Trending." As long as a LOW HEAT mode is making progress in warming the space, the control will hold off on a HIGH HEAT mode. This is relevant for the space sensor machine control types (C TYP = 5 and 6) because they may transition into the occupied mode and see an immediate and large heating demand when the set points change. Heat Trend Time (H. T.TM) -- This is the time period upon which the heat trend demand level (/-/2. T.LV) operates and may work to hold off staging or a HIGH HEAT mode. This is not applicable to VAV control types (CTYP=-I and 2) in the occupied period. See "Heat Trend Demand Level" section for more details.

This menu also contains the cool trip points as well. See Table 67 at the local display under Run Status--c TRIP The control will call out a low or high heat mode by comparing the controlling temperature to the heating set point and the heating set point offset. The set point offsets are used as additional help in customizing and tweaking comfort into the building space. The controlling temperature is "TEMP" and is in the middle of the table for easy reference. Also, the "HVAC" mode can be viewed at the bottom of the table.

This is intended for tempering mode and tempering economizer air when in a cooling mode and the dampers are fully closed. Tempering can also be used during a preoccupancy purge to prevent low temperature air from being delivered to the space. Tempering for staged gas will be discussed in its own section. This section will focus on heat mode control, which ultimately is relevant to tempering, minus the consideration of the supply air heating control point. Staged Gas Heating PID Logic -- The heat control loop is a PID (proportional/integral/derivative) design with exceptions, overrides, and clamps. Capacity rises and falls based on set point and supply-air temperature. When the staged gas control is in Low Heat or Tempering Mode (HVAC mode), the algorithln calculates the desired heat capacity. The basic factors that govern the controlling method are: • • • The staged gas configurations are located at the local display under (bnfiguration -+HEAT-+SGCF. See Table 68. Staged Gas Heat Type (HT.ST) -- This configuration number of stages and the order that are they staged. The supply fan for staged gas heating is controlled by the integrated gas control (IGC) boards and, unless the supply fan is on for a different reason, it will be controlled by the IGC indoor fan input. The unit will control stages of heat to the heating control point (Run Status-+VIEW-+HT.C.P).

This routine is run once every HT.TM seconds. Every time the routine is run, the calculated sum is added to the control output value. In this manner, integral effect is achieved. Every time this algorithm is run, the following calculation is performed: Error = HT.CPLAT Error last = error calculated previous time P = !aFT.P*(Error) D = HT.D*(Error - Erro_last) The P and D terms are ovemdden to zero if: Error < S.GDB AND Error > - S.GDB AND D < M.R.DB AND D > - M.R.DB. "P + D" are then clamped based on ('ARM. This sum can be no larger or no smaller than +('ARM or -('ARM. Max Cap Change per Cycle (('ARM) -- This configuration lhnits the maxhnum change in capacity per PID mn time cycle. S.Gas DB Min.dF/PID Rate (M.R.DB) -- This configuration is a deadband minimum temperature per second rate. See Staged Gas Heating logic below for more details. St.Gas Temp.Dead Band (S.GDB) -- This configuration is a deadband delta temperature. See Staged Gas Heating logic below for more details. Heat Rise in dF/Sec Clamp (RISE) -- This configuration prevents the heat from staging up when the leaving-air temperamre is rising too fast. LAT Limit Config (EAT.L) -This configuration senses when leaving-air temperature is outside a delta temperature band around set point and allows staging to react quicker. Finally, the desired capacity is calculated: Limit Switch Monitoring? (LIM.M) -- This configuration allows the operation of the lhnit switch monitoring routine. This should be set to NO as a limit switch temperature sensor is not used with A Series units. Staged Gas Capacity Calculation = "P + D" + old Staged Gas Capacity Calculation NOTE: The PID values should not be modified without approval from Carrier. Limit Switch High Temp (SW.H. T) -- This configuration is the temperature limit above which stages of heat will be removed. IMPORTANT: When gas or electric heat is used in a VAV application with third party terminals, the HIR relay output must be connected to the VAV terminals in the system in order to enforce a minhnum heating airflow rate. The installer is responsible to ensure the total minimum heating cfin is not below lhnits set for the equipment. Failure to do so will result in lhnit switch tripping and may void warranty. Limit Switch Low Temp (SW..L. T) -- This configuration is the temperature limit above which no additional stages of heat will be allowed. 53 Table 68 -- Staged Gas Configuration ITEM EXPANSION J SG.

These staging patterns are selected based on the model number. The selection of a set of staging patterns is controlled via the heat stage type configuration parameter (HT.ST). As the heating capacity rises and falls based on demand, the staged gas control logic will stage the heat relay patterns up and down, respectively. The Heat Stage Type configuration selects one of 4 staging patterns that the stage gas control will use. In addition to the staging patterns, the capacity for each stage is also determined by the staged gas heating PID control. Therefore, choosing the heat relay outputs is a function of the capacity desired, the heat staging patterns based on the heat stage type (HT.ST) and the capacity presented by each staging pattem. As the staged gas control desired capacity rises, it is continually checked against the capacity of the next staging pattern. J UNITS INTEGRATED GAS CONTROL BOARD LOGIC -- All gas heat units are equipped with one or more integrated gas control (IGC) boards. This board provides control for the ignition system for the gas heat sections.

On size 020-050 high heat units and 051 and 060 low heat units there are two IGC boards. On size 051 and 060 high heat units there are three IGC boards. When a call for gas heat is initiated, power is sent to W on the IGC boards. For standard 2-stage heat, all boards are wired in parallel. For staged gas heat, each board is controlled separately. When energized, an LED on the IGC board will be turned on. See Table 74 for LED explanations. Each board will ensure that the rollont switch and limit switch are closed. The induced-draft motor is then energized. When the speed of the motor is proven with the Hall Effect sensor on the motoc the ignition activation period begins. The burners ignite within 5 seconds. If the burners do not light, there is a 22-second delay before another 5-second attempt is made. If the burners still do not light, this sequence is repeated for 15 minutes. After 15 minutes have elapsed and the burners have not ignited then heating is locked out. The control will reset when the request for W (heat) is temporarily removed. When ignition occurs, the IGC board will continue to monitor the condition of the rollout switch, limit switches, Hall Effect sensor, and the flame sensor. Forty-five seconds after ignition has occurred, the IGC will request that the indoor fan be turned on. The IGC fan output (IFO) is connected to the indoor fan input on the MBB which will indicate to the controls that the indoor fan should be turned on (if not already on). If for some reason the overtemperature limit switch trips prior to the start of the indoor fan blowec on the next attempt the 45-second delay will be shortened by 5 seconds. Gas will not be interrupted to the burners and heating will continue. Once modified, the fan delay will not change back to 45 seconds unless power is reset to the control. The IGC boards only control the first stage of gas heat on each gas valve. The second stages are controlled directly from the MBB board. The IGC board has a minimum on-tflne of 1 minute. In modes such as Service Test where long minimum on times are not enforced, the 1-minute tflner on the IGC will still be followed and the gas will remain on for a minflnum of 1 minute. When the desired capacity is greater than or equal to the capacity of the next staging pattern, the next heat stage is selected (Run Status-+VIEW-+HT.ST = Run Status-+VIEW-+ HT.ST + 1). Similarly, as the capacity of the control drops, the desired capacity is continually checked against the next lower stage. When the desired capacity is less than or equal to the next lower staging pattem, the next lower heat stage pattern is selected (Run Status-+VIEW-+HT.ST = Run Status-+VIEW-+ HT.ST- 1). The first two staged gas heat outputs are located on the MBB board and outputs 3, 4, 5, and 6 are located on the SCB board. These outputs are used to produce 5 to 11 stages as shown in Tables 69A and 69B. The heat stage selected (Run Status-+VIEW-+HT.ST) is clamped between 0 and the maximum number of stages possible (Run Status-+ VIEW-+H.MAX) for the chosen set of staging patterns. See Tables 70-73.

Determine a location in the supply duct that will provide a fairly uniform airflow. Typically this would be a minimum of 5 equivalent duct diameters downstream of the unit. Also, care should be taken to avoid placing the thermistor within a direct line-of-sight of the heating element to avoid radiant effects.

The Morning Warm Up Period is CCN linkage and is relayed in the following conditions: • • TEMPERING MODE -- In a vent or cooling mode, the rooftop may encounter a situation where the economizer at mini1hum position is sending cold outside air down the ductwork of the building. Therefore, it may be necessary to bring heat on to counter-effect this low supply-air temperature. This is referred to as the tempering mode.

Installing a New Sensor -- A field-provided duct-mount temperature sensor (Carrier P/N 33ZCSENPAT or equivalent 10 kilo-otnn at 25 C NTC [negative temperature coefficient] sensor) is required.

SASP -20-80 dF TEMPVUNC 5O Operation -- First, the unit must be in a vent mode, a low cool mode, or a high cool HVAC mode to be considered for a tempering mode. Secondly, the tempering mode is only allowed when the rooftop is configured for staged gas (Configuration --_HEA T--_HT. CF=3 ). If the control is configured for staged gas, the control is in a vent, low cool, or high cool HVAC mode, and the rooftop control is in a situation where the economizer must maintain a minimum position, then the evaporator discharge temperature (EDT) will be monitored. If the EDT falls below a particular trip point then the tempering mode may be called out: Re-Using the Factory SAT Sensor -- The factory sensor is attached to one of the supply fan housings. Disconnect the sensor from the factory harness. Drill a hole insert the sensor through the duct wall and secure in place. Attach the new conductor cable to the sensor leads and terminate in an appropriate junction box. Connect the opposite HVAC mode = "Tempering 56 Vent" HVACmode = "Tempering LoCool" HVACmode = "Tempering HiCool" Thedecision making/selection process forthetempering tripsetpointisasfollows: • If anHVACcoolmode isineffect, thentheventtrippointis • • • T.(Z. If in a pre-occupied purge mode (Operating Modes-+ MODE-+IAQ.P=ON), then the trip point is T.PRG. If in an occupied mode (Operating Modes-+MODE ---)IAQ.P=ON), then the trip point is T.V.OC. For all other cases, the trip point is T. EUN. pressure and calculates the error from set point. This error is simply the duct static pressure set point minus the measured duct static pressure. The error becomes the basis for the proportional term of the PID. The routine also calculates the integral of the error over trine, and the derivative (rate of change) of the error. A value is calculated as a result of this PID routine, and this value is then used to create an output signal used to adjust the VFD to maintain the static pressure set point. Static pressure reset is the ability to force a lowering of the static pressure set point through an external control signal. The unit controls support this in two separate ways, through a 4 to 20 mA signal input wired to the unit's isolator board input terminals (third party control) or via CCN. NOTE: The unoccupied economizer free cooling mode does not qualify as a HVAC cool mode as it is an energy saving feature and has its own OAT lockout already. The unoccupied free cooling mode (HVAC mode = Unocc. Free Cool) will override any unoccupied vent mode from triggering a tempering mode. When employing the CCN, this feature uses the colrnnunications capabilities of VAV systems with ComfortID TM terminals under linkage. The system dynamically determines and maintains an optrinal duct static pressure set point based on the actual load conditions in the space. This can result in a significant reduction in required fan energy by lowering the set point to only the level required to maintain adequate airflow throughout the system. If OAT is above the chosen tempering set point, tempering will not be allowed. Additionally, tempering mode is locked out if any stages of mechanical cooling are present. A minimum amount of time must pass before calling out any tempering mode. In effect, the EDT must fall below the trip point value -1 ° F continuously for a minrinum of 2 minutes. Also, at the end of a mechanical cooling cycle, there must be a minrinum 10 minutes of delay allowed before considering tempering during vent mode in order to allow any residual cooling to dissipate from the evaporator coil. SETTING UP THE SYSTEM -- The options for static pressure control are found under the Local Display Mode Configuration-+SP See Table 75. Failure to correctly configure SRCF and SRFN when operating in VFD Bypass mode will result in the indoor fan motor running continuously. Damage to unit could result. If the above conditions are met, the algorittun is free to select the tempering mode (MODETEMP). If a tempering mode becomes active, the modulating heat source (staged gas) will attempt to maintain leaving-air temperature (LAT) at the tempering set point used to trigger the tempering mode. The technique for modulation of set point for staged gas and hydronic heat is the same as in a heat mode. More information regarding the operation of heating can be referenced in the Heating Control section. Static Pressure Configuration(SRCF) --This variable is used to configure the use of (_l_fortLink TM controls for static pressure control. There are the following options: -- There will be no static pressure control by (_nfortLink controls. This setting would be used for a constant volume (CV) application when static pressure control is not required or for a VAV application if there will be third-party control of the VFD. In this latter case, a suitable means of control must be field installed. Recovery from a tempering mode (MODETEMP) will occur when the EDT rises above the trip point. On any change in HVACMODE, the tempering routine will re-assess the tempering set point which may cause the control to continue or exit tempering mode. Additionally, SR(_T must be set to 0 (None) when a unit is equipped with optional VFD bypass and is operating in Bypass mode. Failure to change this configuration in Bypass mode will result in the indoor fan motor running continuously. Static Pressure Control -- Variable air volume (VAV) air-conditioning systems must provide varying amounts of air to the conditioned space. As air terminals downstream of the unit modulate their flows, the unit must maintain control over the duct static pressure in order to accolmnodate the needs of the terminals and meet the varying combined airflow requirement. 1 (VFD Control) -- This will enable the use of (_n?fortLink controls for static pressure control via a supply fan VFD. Static Pressure Fan Control? (SRFN) -- This is automatically set to Yes when SRCF = 1. When the user would like the 4 to 20 mA output to energize the VFD, as opposed to the fan relay, SRFNmay be set to Yes when SR(_T = 0. When the control turns the fan ON, the control will send the SRMX value of the 4 to 20 mA signal to the third party VFD control. A 48/50AK,AY, A3,A5 unit equipped with a duct pressure control system is provided with a variable frequency drive (VFD) for the supply fan. The speed of the fan can be controlled directly by the (_l_fortLink TM controls. A transducer is used to measure duct static pressure. The signal from the transducer is received by the ECB-2 board and is then used in a PID control routine that outputs a 4 to 20 mA signal to the VFD. Additionally, SRFN must be set to NO when the unit is equipped with optional VFD bypass and is operating in Bypass mode. Failure to change this configuration in bypass mode will result in the indoor fan motor running continuously. Generally, only VAV systems utilize static pressure control. It is required because as the system VAV terminals modulate closed when less air is required, there must be a means of controlling airflow from the unit, thereby effectively preventing overpressurization and its accompanying problems. Static Pressure Sensor (SRS) -- This variable enables the use of a supply duct static pressure sensor. This must be enabled to use (_l_fortLink controls for static pressure control. If using a third-party control for the VFD, this should be disabled. Static Pressure Low Range (SP.LO) -- This is the minimum static pressure that the sensor will measure. For most sensors this will be 0 in. wg. The (_nfortLink controls will map this value to a 4 mA sensor input. The three most fundamental configurations for most applications are Configuration--cSP--cSRCF, which is the static pressure control type, Configuration-+SP-+SRS, used to enable the static pressure sensor, and Configuration-+SP --+SRSP, the static pressure set point to be maintained. Static Pressure High Range (SP..H1) -- This is the maximum static pressure that the sensor will measure. Colrnnonly this will be 5 m. wg. The (_n_fortLink controls will map this value to a 20 mA sensor input. OPERATION -- On units equipped with a VFD and a proper static pressure sensor, when SRCF, SRS and SRSP are configured, a PID routine periodically measures the duct static 57 Static Pressure Set Point (SRSP) -- This is the static pressure control point. It is the point against which the (_l_fortLink controls compare the actual measured supply duct pressure for determination of the error that is used for PID control. Generally one would set SRSP to the minimum value necessary for proper operation of air terminals in the conditioned space at all load conditions. Too high of a value will cause unnecessary fan motor power consumption at part-load conditions and/or noise problems. Too low a value will result in insufficient airflow. directly to the 0 to 3 in. wg of reset. Therefore 2 mA reset is 2/16 * 3 in. wg = 0.375 in. wg of reset. If the static pressure set point (SRSP) = 1.5 in. wg, then the static pressure control point for the system will be reset to 1.5 - 0.375 = 1.125 in. wg. When SRRS = 4, the static pressure reset function acts to provide direct VFD speed control where 4 mA = 0% speed and 20 mA = 100% (SRMN and SRMX will override). Note that SRCF must be set to 1 (VFD Control), prior to configuring SRRS = 4. Failure to do so could result in damage to ductwork due to overpressurization. This is the recolmnended approach if a third party wishes to control the variable speed supply fan. In effect, this represents a speed control signal "pass through" under normal operating circumstances. The (_l_fortLink control system ovemdes the third party signal for critical operation situations, most notably smoke and fire control. VFD Minhnum Speed (SRMN) -- This is the minhnum speed for the supply fan VFD. Typically the value is chosen to maintain a minhnum level of ventilation. NOTE: Most VFDs have a built-in minimum speed adjustment which must be configured for 0% when using (_nfortLink controls for static pressure control. Static Pressure Reset Ratio (SRRT) -- This option defines the reset ratio in terms of static pressure versus temperature. The reset ratio determines how much is the static pressure reduced for every degree below set point for RAT or SPT. VFD Maximum Speed (SRMX) -- This is the maximum speed for the supply fan VFD. This is usually set to 100%. VFD Fire Speed Override (SRFS) -- This is the speed that the supply fan VFD will use during the pressurization, evacuation and purge fire modes. This is usually set to 100%. Static Pressure Reset Limit (SRLM) -- This option defines the maximum amount of static pressure reset that is allowed. This is sometimes called a "clalnp." Static Pressure Reset Configuration (SRRS) -- This option is used to configure the static pressure reset function. When SRRS = 0, there is no static pressure reset via an analog input. If the outdoor air quality sensor is not configured (Configuration---_IAQ---_IAQ. (T_OQ.A. C = 0), then it is possible to use the outdoor air quality sensor location on the CEM board to perform static pressure reset via an external 4 to 20 mA input. NOTE: Resetting static pressure via RAT and SPT is prhnarily a constant volume application which utilizes a VFD. The reasoning is that there is significant energy savings in slowing down a supply fan as opposed to running full speed with supply air reset. Maintaining the supply air set point and slowing down the fan has the additional benefit of working around dehumidification concerns. Configuring SRRS = 1 provides static pressure reset based on this CEM 4 to 20 mA input and ranged from 0 to 3 in. wg. Wire the input to the CEM using TB6-11 and 12. When SRRS = 2, there is static pressure reset based on RAT and defined by SRRTand SRLM. WhenSRRS = 3, there is static pressure reset based on SPT and defined by SRRTand SRLM. Static Pressure Reset Economizer Position (SRE(_) -- This option effectively resets ECONOM1N to fully occupied ventilation position, to account for the drop in static pressure during static pressure reset control. The static pressure reset for the calculation cannot be larger than the supply air static set point (SPSP). The calculation is as follows: Setting SRRS to 1, 2 or 3 will give the user the ability to reset from 0 to 3 in. wg of static pressure. The reset will apply to the supply static pressure set point. The static pressure reset function will only act to reduce the static pressure control point. (Static Pressure Reset/SPSP) x (ECONOSPR- ECONOM1N) As an example, the static pressure set point (SPSP) = 1.5 in. wg. The current static pressure reset is set to 0.5 in. wg. The settings for ECONOSPR = 50% and ECONOM1N = 20%. As an example, the static pressure reset input is measuring 6 mA, and is therefore resetting 2 mA (6 mA - 4 mA) of its 16 mA control range. The 4 to 20 mA range corresponds Table 75 -- Static Pressure Control Configuration ITEM SP EXPANSION RANGE UNITS CCN POINT DEFAULT SUPPLY STATIC PRESS.CFG. SP.CF SP.FN Static Pres. VFD Control?

In effect, for the positioning of the economizer, ECONOMIN would now be replaced by ECONOMIN + 10%. case, the installer could enter 3.0 in. wg as the supply static pressure set point and allow the air terminal system to dynamically adjust the supply duct static pressure set point as required. The system will deter]nine the actual set point required delivering the required airflow at every terminal under the current load conditions. The set point will always be the lowest value under the given conditions. As the conditions and airflow set points at each terminal change throughout the operating period, the equipment static pressure set point will also change. Static Pressure PID Config (S.PID) -- Static pressure PID configuration can be accessed under this heading in the Configuration--+SP submenu. Under most operating conditions the control PID factors will not require any adjustment and the factory defaults should be used. If persistent static pressure fluctuations are detected, small changes to these factors ]nay improve performance. Decreasing the factors generally reduce the responsiveness of the control loop, while increasing the factors increase its responsiveness. Note the existing settings before making changes, and seek technical assistance from Carrier before making significant changes to these factors. The CCN system must have access to a CCN variable (SPRESET which is part of the equipment controller). In the algorithin for static pressure control, the SPRESET value is always subtracted from the configured static pressure set point by the equipment controller. The SPRESET variable is always checked to be a positive value or zero only (negative values are limited to zero). The result of the subtraction of the SPRESET variable from the configured set point is limited so that it cannot be less than zero. The result is that the system will dynamically deter]nine the required duct static pressure based on the actual load conditions currently in the space. This eliminates the need to calculate the design supply static pressure set point. This also saves the energy difference between the design static pressure set point and the required static pressure. Static Pressure PID Run Rate (S.PID--cSRTM) This is the number of seconds between duct static pressure readings taken by the (_n_fortLink TM PID routine. Static Pressure the proportional loop. Plvportional Gain (S.PID--cSRP) This is gain for the static pressure control PID control Static Pressure Integlwl Gain (S.PID--)SRI) This is the integral gain for the static pressure control PID control loop. Third Party 4 to 20 mA Input -- It is also possible to perform static pressure reset via an external 4 to 20 mA signal connected to the CEM board where 4 mA corresponds to 0 m. wg of reset and 20 mA corresponds to 3 in. wg of reset. The static pressure 4 to 20 mA input shares the same input as the analog OAQ sensor. Therefore, both sensors cannot be used at the same thne. To enable the static pressure reset 4 to 20 mA sensor, set (Configuration---_SP---_SRRS) to Enabled. Static Pressure Derivative Gain (S.PID-+SRD) This is the derivative gain for the static pressure control PID control loop. Static Pressure System Gain (S.PID--)SRSG) -- This is the system gain for the static pressure control PID control loop. STATIC PRESSURE RESET OPERATION --The (_nfortLink controls support the use of static pressure reset. The Linkage Master terminal monitors the primary air damper position of all the terminals in the system (done through LINKAGE with the new ComfortID TM air terminals). RELATED POINTS -- These points represent static pressure control and static pressure reset inputs and outputs. See Table 76. The Linkage Master then calculates the amount of supply static pressure reduction necessary to cause the most open damper in the system to open more than the minimum value (60%) but not more than the maximum value (90% or negligible static pressure drop). This is a dynamic calculation, which occurs every two minutes when ever the system is operating. The calculation ensures that the supply static pressure is always enough to supply the required airflow at the worst case terminal but never more than necessary, so that the prhnary air dampers do not have to operate with an excessive pressure drop (more than required to maintain the airflow set point of each individual terminal in the system). Static Pressure mA (SR_ -- This variable reflects the value of the static pressure sensor signal received by the (_nfortLink TM controls. The value ]nay be helpful in troubleshooting. Static Pressure mA Trim (SRM.T) -- This input allows a modest amount of trhn to the 4 to 20 mA static pressure transducer signal, and can be used to calibrate a transducer. As the system operates, if the most open damper opens more than 90%, the system recalculates the pressure reduction variable and the value is reduced. Because the reset value is subtracted from the controlling set point at the equipment, the pressure set point increases and the primary-air dampers close a little (to less than 90%). If the most open damper closes to less than 60%, the system recalculates the pressure reduction variable and the value is increased. This results in a decrease in the controlling set point at the equipment, which causes the primary-air dampers to open a little more (to greater than 60%). Static Pressure Reset (SRRS) -- This variable reflects the value of a static pressure reset signal applied from a CCN system. The means of applying this reset is by forcing the value of the variable SPRESET through CCN. Static Pressure Reset mA (SRR.M) -- This input reflects the value of a 4 to 20 mA static pressure reset signal applied to TB6 terminals 11 and 12 on the CEM board, from a third party control system. Supply Fan VFD Speed (S. VFD) -- This output can be used to check on the actual speed of the VFD. This ]nay be helpful in some cases for troubleshooting. Fan Status Monitoring GENERALThe A Series (_n_fortLink controls offer the capability to detect a failed supply fan through either a duct static pressure transducer or an accessory discrete switch. The fan stares switch is an accessory that allows for the monitoring of a discrete switch, which trips above a differential pressure drop across the supply fan. For any unit with a factory-installed duct static pressure sensoc it is possible to measure duct pressure rise directly, which removes the need for a differential switch. All 48/50AK,AW, A3,A5 units with a factory-installed supply fan VFD will have the duct static pressure sensor as standard. The rooftop unit has the static pressure set point progralrnned into the CCN control. This is the maximum set point that could ever be achieved under any condition. To simplify the installation and connnissioning process for the field, this system control is designed so that the installer only needs to enter a lnaxilnum duct design pressure or lnaximum equipment pressure, whichever is less. There is no longer a need to calculate the worst case pressure drop at design conditions and then hope that some intermediate condition does not require a higher supply static pressure to meet the load conditions. For example, a system design requirement ]nay be 1.2 in. wg, the equipment ]nay be capable of providing 3.0 in. wg and the supply duct is designed for 5.0 in. wg.

Economizer E The economizer control is used to manage the outside and return air dampers of the unit to provide ventilation air as well as free cooling based on several configuration options. This section contains a description of the economizer and its ability to provide free cooling. See the section on Indoor Air Quality Control on page 67 for more information on setting up and using the economizer to perform demand controlled ventilation (DCV). See the Third Party Control section for a description on how to take over the operation of the economizer through external control. Fan Fail Shuts Down Unit (SFS.S) -- This configuration will configure the unit to shut down on a supply fan status fail or shnply alert the condition and continue to run. When configured to YES, the control will shut down the unit if supply fan stares monitoring fails and the control will also send out an alarm. If set to NO, the control will not shut down the unit if supply fan status monitoring fails but will send out an alert. SUPPLY FAN STATUS MONITORING LOGIC -- Regardless of whether the user is monitoring a discrete switch or is monitoring static pressure, the thning for both methods are the same and rely upon the configuration of static pressure control. The configuration that determines static pressure control is Configurafion--)SP--)SRCF. If this configuration is set to 0 (none), a fan failure condition must wait 60 continuous seconds before taking action. If this configuration is 1 (VFD), a fan failure condition must wait 3 continuous minutes before taking action. The economizer system also permits this unit to perform smoke control functions based on external control switch inputs. Refer to the Smoke Control Modes section for detailed discussions. Economizer control can be based on automatic control algoritlnns using unit-based set points and sensor inputs. This economizer control system can also be managed through external logic systems. If the unit is configured to monitor a fan stares switch (SFS.M = 1), and if the supply fan colmnanded state does not match the supply fan status switch for 3 continuous minutes, then a fan status failure has occurred. If the unit is configured (SFS.M = 2), then • • for supply duct pressure The economizer system is a factory-installed option. This unit can also have the following devices installed to enhance economizer control: • • monitoring NOTE: All these options require the controls ule (CEM). If the supply fan is requested ON and the static pressure reading is not greater than 0.2 in. wg for 3 continuous minutes, a fan failure has occurred. If the supply fan is requested OFF and the static pressure reading is not less than 0.2 in. wg for 3 continuous minutes, a fan failure has occurred. Economizer Minimum Position (ECMN) -- The configuration option ECMN is the economizer lninimum position.

Differential D1T Bulb Changeover -- As both return air and outside air temperature sensors are installed as standard on these units, the user may select this option, E.SEL = 1, to perform a qualification of return and outside air in the enabling and disabling of free cooling. If this option is selected and outside-air temperature is greater than return-air temperature, free cooling will not be allowed. Diff'erential Enthalpy Changeover -- This option compares the outdoor-air enthalpy to the return air enthalpy and chooses the option with the lowest enthalpy. This option should be used in climates with high humidity conditions. This option uses both humidity sensors and dry bulb sensors to calculate the enthalpy of the outdoor and return air. An accessory outdoor air humidity sensor (OR!-LS) and return air humidity sensor (RRH.S) are used. The outdoor air relative humidity sensor config (OR!-LS) and return air humidity sensor config (Configuration--cUNIT--cSENS--cRRI-L.S) must be enabled. Outdoor Enthalpy Changeover-This option should be used in climates with higher humidity conditions. The A Series control can use an enthalpy switch or enthalpy sensor, or the standard installed outdoor dry bulb sensor and an accessory relative humidity sensor to calculate the enthalpy of the air. Setting Configuration-+ECON-+E.SEL = 2 requires that the user configure (bnfiguration-cECON_OA.E.(; the Outdoor Enthalpy Changeover Select, and install an outdoor relative humidity sensor. Once the sensor is installed, enable (bnfiguration--cECON_ORH.S, the outdoor relative humidity sensor configuration option. Outdoor Dewpoint Limit Check -- If an outdoor relative humidity sensor is installed, then the control is able to calculate the outdoor air dewpoint temperature and will compare this temperature against the outside air dewpoint temperature limit configuration (Configuration--cECON--_,O.DEW). If the outdoor air dewpoint temperature is greater than O.DEW, then free cooling will not be allowed. Figure 11 shows a horizontal limit line in the custom curve of the psychrometric chart. This is the outdoor air dewpoint limit boundary. If the user selects one of the Honeywell curves, A,B,C or D, then OA.E.C options 1-4 should be selected. See Fig. 10 for a diagram of these curves on a psychrometric chart. 61 Table 79 -- Economizer Configuration ITEM EC.EN EC.MN EC.MX E.TRM E. SEL OA.E.C OA.EN OAT.L O.DEW ORH.S E. TYP EC.SW E.

Once the need for cooling has been satisfied during this cycle, the fan will be stopped. Configuring the economizer for Unoccupied Economizer Free Cooling is done in the UEFC group. There are three configuration options, FC CF, FC TM and FCLO. Unoccupied Economizer Free Cooling Configuration (F(2: CF) -- This option is used to configure the type of unoccupied economizer free cooling control that is desired. 0 = disable unoccupied economizer free cooling 1 = perform unoccupied economizer free cooling as available during the entire unoccupied period. 2 = perform unoccupied economizer free cooling as available, FC TM minutes before the next occupied period. Unoccupied Economizer Free Coolin_ Time Configuration (FC TM) -- This option is a configurable time period, prior to the next occupied period, that the control will allow unoccupied economizer free cooling to operate. This option is only applicable when FCCF = 2. Custom Psychrometric Curves -- Refer to the psychrometric chart and the standard Honeywell A-D curves in Fig. 10. The curves start from the bottom and rise vertically, angle to the left and then fold over. This corresponds to the limits imposed by dry bulb changeover, outdoor enthalpy changeover and outdoor dewpoint limiting respectively. Therefore, it is now possible to create any curve desired with the addition of one outdoor relative humidity sensor and the options for changeover now available. See Fig. 11 for an example of a custom curve constructed on a psychrometric chart. UNOCCUPIED ECONOMIZER FREE COOLING -- This Free Cooling function is used to start the supply fan and use the economizer to bring in outside air when the outside temperature is cool enough to pre-cool the space. This is done to delay the need for mechanical cooling when the system enters the occupied period. This function requires the use of a space temperature sensor.

When the Unoccupied Economizer Free Cooling mode is active, the supply fan is turned on and the economizer damper modulated to control to the supply air set point (Setpoiuts-+ SASP) plus any supply air reset that may be applied (Inputs'--+ RSE T--+SA.S.R ). ECONOMIZER OPERATION CONFIGURATION -- The configuration items in the E.CTG menu group affect how the economizer modulates when attempting to follow an economizer cooling set point. Typically, they will not need adjustment. In fact, it is strongly advised not to adjust these configuration items from their default settings without first consulting a service engineering representative. Economizer Suction Pressure Reset for Two-Stage Cooling-If the unit's control type is set to either 2-stage thermostat or 2-stage space temperature control, then there is no cooling control point. Stages 1 and 2 are brought on based on demand, irrespective of the evaporator discharge temperature. In this case, the economizer monitors suction pressure and resets the economizer control point accordingly in order to protect the unit from freezing. For those conditions when the economizer opens up fully but is not able to make set point, and then a compressor comes on, it is conceivable that the coil might freeze. This can be indirectly monitored by checking suction pressure. Rather than fail a circuit, the control will attempt to protect the unit by resetting the economizer control point until the suction pressure rises out of freezing conditions. In addition, the economizer cooling algorithm is designed to automatically slow down the economizer actuator's rate of travel as outside air temperature decreases. ECONOMIZER DIAGNOSTIC HELP -- Because there are so many conditions which might disable the economizer from being able to provide free cooling, the control has a display table to identify these potentially disabling sources. The user can check ACTV, the "Economizer Active" flag. If this flag is set to Yes there is no reason to check DISA (Economizer Disabling Conditions). If the flag is set to No, this means that at least one or more of the flags under the group DISA are set to Yes and the user can discover what is preventing the economizer from performing free cooling by checking the table. If either circuit's suction pressure drops to within 5 psig of the low suction pressure trip point, the control will start adding reset to the economizer control point if it is active. It will be possible to reset the control point upwards, 10 degrees (2 degrees per psig), between the low suction pressure trip point of 52 psig for 48/50AJ,AK,AW, AY units or 93 psig for 48/50A2,A3,A4,A5 units. If this does not work, and if the suction pressure drops below the trip point, then the control will further reset the control point 1 degree every 15 seconds up to a maximum of 10 degrees. The resulting effect will be to warm up the mixed air entering the evaporator, thereby raising the suction pressure. The economizer's reported and commanded positions are also viewable, as well as outside air temperature, relative humidity, enthalpy and dew point temperature. Building Pressure Control E The building pressure control sequence provides control of the pressure in the building through the modulating flow rate function of the modulating power exhaust option. This function also provides control of the constant volume 2-stage power exhaust option. BUILDING PRESSURE CONFIGURATION -- The building pressure configurations are found at the local display under Configuration--+BP. See Table 81. The following information can be found under the Local Display Mode Run Status--+ECDN. See Table 80. Economizer Control Point Determination Logic -- Once the economizer is allowed to provide free cooling, the economizer must determine exactly what set point it should try to maintain.

Thetwotripsetpointsare The number of power exhaust stages available for this control algorithin is a function of the number of motors it supports. This number of motors is defined by the Configuration-9BP -9BRMT configuration. Table 83 illustrates the staging tables for this control algorithin based on BRMT. BRP! and BRP2. If the economizer is greater than or equal to BRP1, then power exhaust stage 1 is requested and a 60-second thner is initialized. If the economizer is 5% below theBRP1, then power exhaust stage 1 is turned off. Also, if the economizer position is less than BRP1 and the 60-second timer has expired, power exhaust stage 1 is turned off. The same logic applies to the second power exhaust stage, except the BRP2 trip point is monitored. If the economizer position is greater than or equal to BRP2, then power exhaust stage 2 is energized and a 60-second timer is initialized. If the economizer is 5% below the BRP2 the second power exhaust stage turned off. If the economizer is less than BRP2 and the 60-second thner has expired, second stage power exhaust is turned off. The following configurations are used in the controlling building pressure with this algorithin: • • • Configuration-9BP-9B.CFG-9BRHP high threshold level) Configuration-9BP-9B.CFG-9BRLP low threshold level) Configuration-9BP-9B.

Any time a stage change is made, a timer is started which delays staging for 10 * BRTM seconds. The default for BRTM is 1, therefore the delay between stage changes is set to 10 seconds.

VFD POWER EXHAUST BUILDING PRESSURE CONTROL (BR(T = 3)--A 4 to 20mA analog output from Economizer Control Board 1 (ECB-1, AO1) is provided as a speed reference for a field-installed VFD power exhaust accessory. If building pressure (Pressures---_AIR.P --+BP) rises above the building pressure set point (BRSP) and the supply fan is on, then building pressure control is initialized. Thereafter, if the supply fan relay goes off or if the building pressure drops below the BRSP minus the building pressure set point offset (BRSO) for 5 continuous minutes, building pressure control will be stopped. The 5-minute timer will continue to reinitialize if the VFD is still colrnnanded to a speed > 0%. If the building pressure falls below the set point, the VFD will slow down automatically. Control is performed with a PID loop Smoke Purge -- TB6-13 and 15 Each mode must be energized individually on discrete inputs and the corresponding alarm is initiated when a mode is activated.

Evacuation, Pressurization and Smoke Purge modes require the Controls Expansion Board (CEM). The Fire Shutdown input is located on the main board (MBB) on terminals TB5-10 and 11. The unit may also be equipped with a factory-installed remm air smoke detector that is wired to TB5-10 and 11 and will shut the unit down if a smoke condition is determined. Field-monitoring wiring can be connected to terminal TB5-8 and 9 to monitor the smoke detector. Inputs on the CEM board can be used to put the unit in the Pressurization, Evacuation, and Smoke Purge modes. These switches or inputs are connected to TB6 as shown below.

It should be set at around 400 to 450 ppm or measured with a handheld sensor during the colrunissioning of the unit. The OAQ reference level can be set using the OAQ Reference Set Point (OAQ. U). When the differential between IAQ and OAQ reaches the configurable Diff. Air Quality Hi Limit (DAQ.H), then the economizer position will be ECMN. When the IAQ-OAQ differential is between DAQ.L and DAQ.H, the control will modulate the damper between IAQ.M and ECMN as shown in Fig. 12. The relationship is a linear relationship but other non-linear options can be used. The damper position will never exceed the bounds specified by IAQ.M and ECMN during IAQ control. Indoor Air Quality Control -- The indoor air quality (IAQ) function will admit flesh air into the space whenever space air quality sensors detect high levels of CO2. When a space or return air CO2 sensor is connected to the unit control, the unit's IAQ routine allows a demand-based control for ventilation air quantity, by providing a modulating outside air damper position that is proportional to CO2 level. The ventilation damper position is varied between a minimum ventilation level (based on internal sources of contaminants and CO2 levels other than from the effect of people) and the maximum design ventilation level (determined at maximum populated status in the building). Demand control ventilation (DCV) is also available when the (_n_fortLink TM unit is connected to a CCN system using ComfortID TM terminal controls. If the building is occupied and the indoor fan is running and the differential between IAQ and OAQ is less than DAQ.L, the economizer will remain at IAQ.M. The economizer will not close completely. The damper position will be 0 when the fan is not running or the building is unoccupied. The damper position may exceed ECMNin order to provide free cooling. The (_nfortLink controller is configured for air quality sensors which provide 4 mA at 0 ppm and 20 mA at 2000 ppm. If a sensor has a different range, these bounds must be reconfigured. These pertinent configurations for ranging the air quality sensors are IQ.R.L, IQ.R.H, OQ.R.L and OQ.R.H. The bounds represent the PPM corresponding to 4 mA (low) and 20 mA (high) for IAQ and OAQ, respectively. This function also provides alternative control methods for controlling the amount of ventilation air being admitted, including fixed outdoor air ventilation rates (measured as cfm), external discrete sensor switch input and externally generated proportional signal controls. IfOAQ exceeds the OAQ Lockout Value (OAQ.L), then the economizer will remain at IAQ.M. This is used to limit the use of outside air which outdoor air CO2 levels are above the OAQ.L limit. Normally a linear control of the damper vs. the IAQ control signal can be used, but the control also supports non-linear control. Different curves can be used based on the Diff.AQ Responsiveness Variable (IAQ.R). See Fig. 13. The IAQ function requires the installation of the factoryoption economizer system. The DCV sequences also require the connection of accessory (or field-supplied) space or return air CO2 sensors. Fixed cfm rate control requires the factoryinstalled outdoor air cfm option. External control of the ventilation position requires supplemental devices, including a 4 to 20 mA signal, a 10 kilo-otnn potentiometer, or a discrete switch input, depending on the method selected. Outside air CO 2 levels may also be monitored directly and high CO 2 economizer restriction applied when an outdoor air CO2 sensor is connected. (The outdoor CO2 sensor connection requires installation of the CEM.) SETT_G UP THE SYSTEM -- The IAQ configuration options are under the Local Display Mode Configuration--+IAQ. See Table 84. Economizer Min Position ((bnfiguration--+IAQ--+DCV.C --+EC.MN) -- This is the fully occupied minimum economizer position. IAQ Demand Vent Min Pos. (Con.figuration--+IAQ--+DCV.C --+IAQ.M) -- This configuration will be used to set the mini1hum damper position in the occupied period when there is no IAQ demand. IAQ Analog Sensor Config (Configuration-9IAQ--9 AQ.(T-+IQ.A.() -- This is used to configure the type of IAQ position control. It has the following options: • IQ.A. C = 0 (No analog input). If there is no other minimum position control, the economizer minimum position will be (bnfiguration--+IAQ--gDCV.C--+E(:MN and there will be no IAQ control. • IQ.A. C = 1 (IAQ analog input). An indoor air (space or return air) CO2 sensor is installed. If an outdoor air CO2 sensor is also installed, or OAQ is broadcast on the CCN, or if a default OAQ value is used, then the unit can perform IAQ control. • IQ.A.C = 2 (IAQ analog input with minimum position override) -- If the differential between IAQ and OAQ is above Configuration---_IAQ--)AQ.SP-+DAQ.11, the economizer minimum position will be the IAQ override position ((bnfiguration---_IAQ---_AQ.SP---_IQ.O.P). • IQ.A. C = 3 (4 to 20 mA minimum position) -- With a 4 to 20 mA signal connected to TB5-6 and 7, the economizer minimum position will be scaled linearly from 0% (4 mA) to EC.MX (20 mA). The (_n_fortLink control system has the capability of DCV using an IAQ sensor. The indoor air quality (IAQ) is measured using a CO2 sensor whose measurements are displayed in parts per million (ppm). The IAQ sensor can be field-installed in the return duct. There is also an accessory space IAQ sensor that can be installed directly in the occupied space. The sensor must provide a 4 to 20 mA output signal and must include its own 24-v supply. The sensor connects to terminal TB5-6 and 7. Be sure to leave the 182-ohin resistor in place on terminals 6 and 7. OPERATION -- The unit's indoor air quality algorithin modulates the position of the economizer damper between two user configurations depending upon the relationship between the IAQ and the outdoor air quality (OAQ). Both of these values can be read at the Inputs--+AIR. Q submenu. The lower of these two configurable positions is referred to as the IAQ Demand Vent Min Position (IAQ.M), while the higher is referred to as Economizer Minimum Position (EC.MN). The IAQ.M should be set to an economizer position that brings in enough fresh air to remove contaminants and CO2 generated by sources other than people. The EC.MNvalue should be set to an economizer position that brings in enough fresh air to remove contaminants and CO2 generated by all sources including people. The EC.MNvalue is the design value for maxflnum occupancy. The logic that is used to control the dampers in response to IAQ conditions is shown in Fig. 12. The (_nfortLink TM controls will begin to open the damper from the IAQ.M position when the IAQ level begins to exceed the OAQ level by a 67 • IQ.A.C = 4 (10K potentiometer minimum position) -With a 10K linear potentiometer connected to TB5-6 and 7_ the economizer minimum position will be scaled linearly from 0% (0 kilo-otnns) to ECMX (10 kilo-otnns). IAQ Analog Fan Config (Configuration---_IAQ---_AQ. _T---_ !Q.A.F) -- This configuration is used to configure the control of the indoor fan. If this option is used then the IAQ sensor must be in the space and not in the return duct. It has the following configurations: • IQ.A.F = 0 (No Fan Start) -- IAQ demand will never override normal indoor fan operation during occupied or unoccupied period and turn it on. • IQ.A.F = 1 (Fan On If Occupied) -- IAQ demand will override normal indoor fan operation and turn it on (if off) only during the occupied period (CV operation with automatic fan). • IQ.A.F = 2 (Fan On Occupied/Unoccupied) -- IAQ demand will always override normal indoor fan operation and turn it on (if off) during both the occupied and unoccupied period. For IQ.A.F = 1 or 2_the fan will be turned on as described above when DAQ is above the DAQ Fan On Set Point ((bnfigurafion--+IAQ--+AQ.SP--+D.EON). The fan will be turned offwhen DAQ is below the DAQ Fan OffSet Point ((bnfiguration--_IAQ--+AQ.SP--_D.EOF). The control can also be set up to respond to a discrete IAQ input. The discrete input is connected to TB5-6 and 7. IAQ Discrete Input Config ((bn.figuration--+IAQ--+AQ.(T --+IQ.L(3 -- This configuration is used to set the type of IAQ sensor. The following are the options: • IQ.LC = 0 (No Discrete Input) -- This is used to indicate that no discrete input will be used and the standard IAQ sensor input will be used. • IQ.LC = 1 (IAQ Discrete Input) -- This will indicate that the IAQ level (high or low) will be indicated by the discrete input.

The occupied status, unit temperatures, unit set points, and stage information can also be shown. See Table 105. the Maximum Cool Stages (MAX.S) -- This variable is the maximum number of cooling stages the control is configured for and capable of controlling. Active Demand Limit (DEM.L) -- If demand limit is active, this variable will represent the amount of capacity that the control is currently limited to. Capacity Load Factor (SMZ) -- This factor builds up or down over time (-100 to +100) and is used as the means of adding or subtracting a cooling stage during run time. It is a normalized representation of the relationship between "Sum" and "Z". See the SUMZ Cooling Algorithm section on page 46. Next Stage EDT Decrease (ADD.R) -- This variable represents (if adding a stage of cooling) how much the temperature should drop in degrees depending on the R.PCT calculation and how much additional capacity is to be added. Run Status--_VIEW_OCCThis variable displays the current occupancy status of the control. Run Status--_VIEW--_MAT--This variable displays the current value for lnixed-air temperature.

For a unit with 4 stages, each stage represents about 7.5 ° F of change to EDT. If stages could reliably be cycled at very fast rates, the set point could be maintained very precisely. Since it is not desirable to cycle compressors more than 6 cycles per hour, slow change override takes care of keeping the PID under control when "relatively" close to set point. * (-10 + (4* (-SUB.R))) *0.6 Cap Threshold Adding (Z.PLU) -- This parameter is used in the calculation of SMZ and is calculated as follows: Z.PLU = (bnfiguration--c(OOL--cZGN (-ADD.R))) * 0.6 * (10 + (4* MODE TRIP HELPER -- The Mode Trip Helper table provides information on the unit modes and when the modes start and stop. See Table 108. This information can be used to help determine why the unit is in the current mode. High Temp Cap Override (H. IMP) -- if stages of mechanical cooling are on and the error is greater than twice Y.PLU, and the rate of change of error is greater than 0.5° E then a stage of mechanical cooling will be added every 30 seconds. This override is intended to react to situations where the load rapidly increases. Low Temp Cap Override (L. IMP) -- If the error is less than twice Y.MIN, and the rate of change of error is less than -0.5 ° E then a mechanical stage will be removed every 30 seconds. This override is intended to quickly react to situations where the load is rapidly reduced. Pull Down Cap Override (PULL) -- If the error from set point is above 4° E and the rate of change is less than -1 ° F per minute, then pulldown is in effect, and "SUM" is set to 0. This keeps mechanical cooling stages from being added when the error is very large, but there is no load in the space. Pulldown for units is expected to rarely occur, but is included for the rare situation when it is needed. Most likely pulldown will occur when mechanical cooling first becomes available shortly after the control goes into an occupied mode (after a warm unoccupied mode).

When this occurs, the control turns offthe compressor and logs a strike for the respective circuit. These alerts reset automatically. If the current sensor board reads OFF while the compressor relay has been COlrunanded ON for a period of 4 continuous seconds, an alert is generated. Any time this alert occurs, a strike will be called out on the affected compressor. If three successive strikes occur the compressor will be locked out requiring a manual reset or power reset of the circuit board. The clearing of strikes during compressor operation is a combination of 3 complete cycles or 15 continuous minutes of run time operation. So, if there are one or two strikes on the compressor and three short cycles (ON-OFF, ON-OFF, ON-OFF) less than 15 minutes each occur, the strikes will be reset to zero for the affected compressor. Also, if the compressor turns on and runs for 15 minutes straight with no compressor failure, the compressor's strikes are cleared as well. All alarms are displayed with a code of AXXX where the A is the category of alarm (Pre-Alert, Alert, or Alarm) and XXX is the number. The response of the control system to various alerts and alarms depends on the seriousness of the particular alert or alarm. In the mildest case, an alert does not affect the operation of the unit in any manner. An alert can also cause a "strike." A "striking" alert will cause the circuit to shut down for 15 minutes. This feature reduces the likelihood of false alarms causing a properly working system to be shut down incorrectly. If three strikes occur before the circuit has an opportunity to show that it can function properly, the circuit will strike out, causing the shutdown alarm for that particular circuit. Once activated, the shutdown alarm can only be cleared via an alarm reset. NOTE: Until the compressor is locked out, for the first two strikes, the alert will not be broadcast to the network, nor will the alarm relay be closed. The possible causes are: • Circuits with strikes are given an opportunity to reset their strike counter to zero. As discussed above, a strike typically causes the circuit to shut down. Fifteen minutes later, that circuit will once again be allowed to run. If the circuit is able to run for 1 minute, its replacement circuit will be allowed to shut down (if not required to run to satisfy requested stages). However, the "troubled" circuit must run continuously for 5 minutes with no detectable problems before the strike counter is reset to zero. All the alarms and alerts are SUlrunarized in Table 114. ALARM I WRITE STATUS string string string string string string string P -- Pre-Alert: Part of the unit is temporarily down. The alarm is not broadcast on the CCN network. The alarm relay is not energized. After an allowable number of retries, if the function does not recover, the pre-alert will be upgraded to an alert or an alarm. T -- Alert: Part of the unit is down, but the unit is still partially able to provide cooling or heating. A -- Alarm: The unit is down and is unable to provide cooling or heating.

For 48/50AJ,AK,AW, AY units: • Compressor internal overload protection is open. The internal overloads are used on the Scroll Tech compressors (black) and smaller Maneurop compressors used on the size 020, 025, 027, 030, 035 units and 040 A1, A2 compressors. • Internal compressor temperature sensor trip. The large Maneurop compressors (blue) used on the size 040 (B1, B2), 050, and 060 units have an internal temperature sensor. • Circuit breaker trip. The compressors are protected from short circuit by a breaker in the control box. On the size 020-035 and 040 A1, A2 units there is one breaker per two compressors and on the size 040 (B1, B2), 050, and 060 compressors there is one breaker per compressor because there are not internal overloads. • Wiring error.

Internal overload protectors are used in the Copeland compressors in all units except size 60 ton units with voltages of 208/230-v, 380-v, and 575-v. • Compressor external overload protector (Kriwan module) has activated. The Copeland compressors in size 60 ton units with voltages of 208/230-v, 380-v, and 575-v use external overload protector modules that are mounted in the compressor wiring junction box. Temperature sensors embedded in the compressor motor windings are the inputs to the module. The module is powered with 120 vac from the units main control box. The module output is a normally closed contact that is wired in series with the compressor contactor coil. In a compressor motor overload condition, the contact opens de-energizing the compressor contactor. • Circuit breaker trip. The compressors are protected from short circuit by a breaker in the control box. On the 020-050 size units there is one breaker per two compressors and on the 060 size units there is one breaker per compressor. Wiring Error. A wiring error might not allow the compressor to start. To check out alerts 051,052, 055 and 056: 1. Turn on the compressor in question using Service Test mode. If the compressor does not start, then most likely the problem is one of the following: HPS open, open internal protection, circuit breaker trip, incorrect safety wiring, or incorrect compressor wiring. 2. If the compressor correct direction. does start verify it is rotating in the IMPORTANT: Prolonged operation in the wrong direction can damage the compressor. Correct rotation can be verified by a gage set and looking for a differential pressure rise on start-up. 95 IMPORTANT: If thecompressor starts,verifythat The cause of the alert is usually a faulty thermistor, a shorted or open thermistor caused by a wiring error, or a loose connection. the indoor and outdoor fans are operating properly. T072 (Evaporator Discharge Reset Sensor Failure) -- If the unit is configured to use the remote EDT 4 to 20 mA reset input ((bnfiguration--cEDT.R--cRES.S) and the sensor reading is less than 2 mA then the alert will occur. When this occurs the control will default to the internal set points. The sensor is connected to the optional CEM module. For this sensor to be used, the EDT 4 to 20 mA reset input ((bnfiguration -+EDT.R-+RES.S) must be set to "enabled." IMPORTANT: If the CS is.always detecting current, then verify that the compressor is on. If the compressor is on, check the contactor and the relay on the MBB. If the compressor is off and there is no current, verify CS wiring and replace if necessary. IMPORTANT: Return to Normal mode and observe compressor operation to verify that compressor current sensor is working and condenser fans are energized after compressor starts. T073 (Outside Air Temperature Thermistor Failure) -- This alert occurs when the outside air temperature sensor (Temperatures-+AIR.T_OAT) is outside the range -40 to 240 F (-40 to 116 C). Failure of this thermistor (Temperatures-+AIR.T_OAT) will disable any elements of the control which requires its use. Economizer control beyond the vent position and the calculation of mixed-air temperature for the sumZ algorithin will not be possible. This alert resets automatically. The cause of the alert is usually a faulty thermistor, a shorted or open thermistor caused by a wiring error, or a loose connection. A051 (Circuit A. Compressor 1 Stuck On Failure) A052 (Circuit A. Compressor 2 Stuck On Failure) A055 (Circuit B. Compressor 1 Stuck On Failure) A056 (Circuit B. Compressor 2 Stuck On Failure) -- Alarm codes 051, 052, 055, and 056 are for compressors A1, A2, B1, B2 respectively. These alarms occur when the current sensor (CS) detects current when the compressor should be off. When this occurs, the control turns offthe compressor and logs a strike for the respective circuit. Use the scrolling marquee to reset the alarm. T074 (Space Temperature Thermistor Failure) -- This alert occurs when the space temperature sensor (Temperatures ---)AIR.T--+SPT) is outside the range -40 to 240 F (-40 to 116 C). This alert will only occur if the unit is configured to use a space temperature sensor. Configuration is done through the Unit Control Type (Configuration--_UNIT-+CTYP) configuration. Failure of this thermistor (Temperatures--+AIR.T--+SPT) will disable any elements of the control which requires its use. If the unit is configured for SPT 2 stage or SPT multi-stage operation and the sensor fails, no cooling or heating mode may be chosen. This alert resets automatically. The cause of the alert is usually a faulty thermistor in the T55, T56, or T58 device, a shorted or open thermistor caused by a wiring error, or a loose connection. T075 (Return Air Thermistor Failure) -- This alert occurs when the remm air temperature sensor (Temperatures--)AIR. T--cRAT) is outside the range -40 to 240 F (-40 to 116 C). The RAT is standard on all units and is located in the return section near the auxiliary control box. This alert resets automatically. The cause of the alert is usually a faulty thermistor, a shorted or open thermistor caused by a wiring error, or a loose connection. If the current sensor board reads ON while the compressor relay has been colnmanded OFF for a period of 4 continuous seconds, an alarm is generated. These alarms are only monitored for a period of 10 seconds after the compressor relay has been colnmanded OFE This is done to facilitate a service technician forcing a relay to test a compressor. In addition, ifa compressor stuck failure occurs and the current sensor board reports the compressor and the request off, certain diagnostics will take place. 1. If any of the 4 compressors are diagnosed as stuck on and the current sensor board is on and the request is off, the control will request the supply fan which will automatically start building airflow control.

Failure of this sensor will disable any elements of the control which requires its use including economizer outdoor and differential enthalpy control. The OA.RH sensor is located in the economizer hood and is used for control of the economizer. The sensor is a loop powered 4 to 20 mA sensor. This alert resets automatically. The cause of the alert is usually a faulty sensor, a shorted or open sensor caused by a wiring error, or a loose connection. The unit must be configured to use the sensor through the Outside Air RH Sensor ((bnfiguration-cE(ON_ORH.S) setting. T064 (Circuit A Saturated Condensing Thermistor Failure) T065 (Circuit B Saturated Condensing Thermistor Failure) -Alert codes 064 and 065 are for circuits A and B, respectively. This alert code is for 48/50AJ,AK,AW, AY units only. These alerts occur when the saturated condensing temperatures (Temperatures-¢REET-cSCT.A and SCT.B) are outside the range -40 to 240 F (-40 to 116 C). When this occurs, the control uses the outdoor temperature (OAT) to control the outdoor fans. The control will default to control based on the OAT sensor and will turn on OFC.B when the ambient is above 65 F and off when the ambient is below 50 E T078 (Return Air Relative Humidity Sensor Failure) -- This alert occurs when the remm air humidity sensor (Inputs--cRELH---_RA.RH) has a reading less than 2 mA. Failure of this sensor (Inputs--cREL.H--cRA.RH) will disable If the SCT and OAT sensors have all failed then the control should turn on OFC.B when compressors are on. 96 any elements of the control which requires its use including economizer differential enthalpy control. The RA.RH sensor is located in the return air section near the auxiliary control box. The sensor is a loop powered 4 to 20 mA sensor. This alert resets automatically. The cause of the alert is usually a faulty sensor, a shorted or open sensor caused by a wiring error, or a loose connection. The unit must be configured to use the sensor through the Outside Air RH Sensor (Configuration--cUNIT--+SENS--+RRI-I.S) setting. T082 (Space Temperature Offset Sensor Failure) -- If the unit is configured to use a space temperature sensor and is using a T56 sensor with an offset potentiometer, then the alert will occur if the potentiometer is outside the allowable range. The control will default to the software applicable set point because there is no offset available that may be applied to space temperamre. The alert will automatically clear. The unit must be configured for one of the SPT control options through the Unit Control Type ((bnfiguration-+UNIT_C TYP) configuration. T090 (Circuit A Discharge Pressure Transducer Failure) T091 (Circuit B Discharge Pressure Transducer Failure) -Alert codes 090, and 091 are for circuits A and B respectively. These alerts occur when the unit is configured for pressure transducers ((bnfiguration--cUNIT---_DRXR) and the pressure is outside the range 0.0 to 667.0 psig. A circuit cannot run when this alert is active. Use the scrolling marquee to reset the alert. The cause of the alert is usually a faulty transducer, faulty 5v power supply, or a loose connection. Although the software supports this option, it is not possible at the time of the writing of this specification to order the optional discharge pressure transducers. of the affected circuit, if it exists, will be shut down with a local alert (P120, P121) and a 10-minute thneguard will be added to the compressor. If saturated suction temperature continues to be less than 20 F for 4 minutes, less than 10 F for 2 minutes, less than 0 ° F for 1 minute or less than -20 F for 20 seconds continuously then compressor no. 1 will be shut down and then an alert or alarm will be issued. This failure follows a 3 strike methodology whereby the first two times a circuit goes down entirely, an alert will be generated which keeps the circuit off for 15 minutes before allowing the circuit to try again. The third time this happens, an alarm will be generated which will necessitate a manual reset to get the circuit back running. It is hnportant to note that a "strike" is called out only if all compressors in the circuit are off at the time of alert!alarm. To prevent nuisance alerts, P120 and P121 show up in the alarm history and locally at the display but are not broadcast to the network. To recover from these alerts, a 10-minute holdoff timer must elapse and the saturated suction temperature must rise above 29.32 F. If recovery occurs, staging will be allowed on the circuit again. Again, a "strike" is tied to the circuit going off entirely, not reducing capacity and recovering. Therefore it is possible that multiple P120 or P121 alerts may be stored in alarm history but not broadcast. If there are 1 or 2 strikes on the circuit and the circuit recovers for a period of thne, it is possible to clear out the strikes thereby resetting the strike counter automatically. The control must have saturated suction temperature greater than or equal to 34 F for 60 minutes in order to reset the strike counters. T122 (Circuit A High Saturated Suction Temperature) T123 (Circuit B High Saturated Suction Temperature) -- Alert codes 122 and 123 occur when compressors in a circuit have been running for at least 5 to 30 minutes ((bnfiguration _'OOL-+H.SSI). On 48/50AJ,AK,AW, AY units, this alert code occurs if the circuit saturated suction temperature is greater than 60 E On 48/50A2,A3,A4,A5 units, this alert code occurs if the circuit saturated suction temperature is greater than 65 F when one compressor is running or 60 F when two compressors are running. For all units, the high saturated suction alert is generated and the circuit is shut down. Alert code 122 is for circuit A and 123 for circuit B. T092 (Circuit A Suction Pressure Transducer Failure) T093 (Circuit B Suction Pressure Transducer Failure) -- Alert codes 092, and 093 are for circuits A and B respectively. These alerts occur when the pressure is outside the following ranges: 0.5 to 134.5 psig when SRXR=O, 0.0 to 200.0 psig when SRXR=I, and 0.0 to 420.0 psig on all 48/50A2,A3,A4,A5 units. A circuit cannot mn when this alert is active. Use the scrolling marquee to reset the alert. The cause of the alert is usually a faulty transducer, faulty 5 v power supply, or a loose connection. T110 (Circuit A Loss of Charge) Till (Circuit B Loss of Charge) -- Alert codes 110, and 111 are for circuits A, and B respectively. These alerts occur when the compressor is OFF and the suction pressure is less than 5 psig for 48/50AJ,AK,AW, AY units or 18 psig for 48/50A2, A3,A4,A5 units and the OAT is above -5 F for 1 continuous minute. The alert will automatically clear when the suction pressure transducer reading is valid and greater than 15 psig for 48/50AJ,AK,AW, AY units or 54 psig for 48/50A2,A3,A4,A5 units. The cause of the alert is usually low refrigerant pressure or a faulty suction pressure transducer. T126 (Circuit A High Head Pressure) T127 (Circuit B High Head Pressure) -- Alert codes 126, and 127 are for circuits A and B respectively. On 48/ 50AJ,AK,AW, AY units, these alerts occur when the appropriate saturated condensing temperature is greater 145 E Prior to the alert, the control will shut down one compressor on a circuit if that circuit's saturated condensing temperature is greater than 140 E If SCT continues to rise to greater than 145 F, the alert will occur and the circuit's remaining compressor will shut down. P120 (Circuit A Low Saturated Suction Temperature -Compressor A2 Shutdown) T120 (Circuit A Low Saturated Suction Temperature Alert) A120 (Circuit A Low Saturated Suction Temperature Alarm) P121 (Circuit B Low Saturated Suction Temperature -Compressor B2 Shutdown) T121 (Circuit B Low Saturated Suction Temperature Alert) A121 (Circuit B Low Saturated Suction Temperature Alarm) -- This alert/alarm is used to keep the evaporator coils from freezing and the saturated suction temperature above the low lfinit for the compressors. On 48/50A2,A3,A4,A5 units, these alerts occur when the appropriate saturated condensing temperature is greater than 150 E Prior to the alert, the control will shut down one compressor on a circuit if that circuit's saturated condensing temperature is greater than 145 F. IfSCT continues to rise to greater than 150 F, the alert will occur and the circuit's remaining compressor will shut down. There will be a start-up delay if the outside-air temperature is too low.

T314 (IAQ Above Limit) -- If the unit is configured to use an CO: sensor and the level (Inputs-+AIR.Q-+IAQ) is above the configurable IAQ High Alert Limit (Configuration--_ ALLM-+IAQ.H) for 5 minutes then the alert will occur. The unit will continue to mn and the alert will automatically reset. A404 (Fire Shutdown Emergency Mode) -- This alarm occurs when the fire shutdown input is active (either open or closed depending upon its configuration). If the fire shutdown input is energized (fire shutdown is in effect), or if two fire smoke modes are incorrectly energized at the same thne, a fire shutdown mode will occur. This is an emergency mode requiring the complete shutdown of the unit. Recovery is automatic when the inputs are no longer on. This alarm is usually caused by an auxiliary device that is trying to shut down the unit (e.g., smoke detector). The input for Fire Shutdown is at Inputs-cFIRE-cFSD. The switch logic configuration for this switch input can be found at variable (bnfiguration-cSW.LG-cFSD.L Verify that the configuration is set correctly, verify the wiring and auxiliary device. This alarm resets automatically. T305 (Return Air Temperature Above Limit) -- If the returnair temperature is below the RAT HI Alert Limit/Occ (Configuration--)ALLM-+RA.I-LO) for 5 minutes or RAT HI Alert Limit!Occ (Configuration -+ALLM-+RA.H.U) for 10 minutes, then an alert will be broadcast. The alert will automatically reset. T308 (Return Air Relative Humidity Below Limit) -- If the unit is configured to use a return air relative humidity sensor through the Return Air RH Sensor ((bnfiguration -+UNIT-+SENS-+RRH.S) setting, and the measured level is below the configurable RH Low Alert Limit (Configuration --)ALLM-+R.RH.L) for 5 minutes, then the alert will occur.

T312 (Building Static Pressure Below Limit) -- If the unit is configured to use a VFD controlled power exhaust or a modulating power exhaust then a building static pressure lhnit can be configured using the BP Low Alert Limit (Configuration ---)ALLM--cBRL). If the measured pressure (Pressures---)AIR.P--cBP) is below the limit for 5 minutes then the alert will occur. If the pressurization input on the CEM is energized, a pressurization mode occurs which flags an alarm. This mode attempts to raise the pressure of a space to prevent smoke infiltration from another space. The space with smoke should be in an Evacuation mode attempting to lower its pressure. Opening the economizer, closing the return-air damper, shut!ing down power exhaust, and turning the indoor fan on will increase pressure in the space. Recovery is automatic when the input is no longer on. If the evacuation input on the CEM is energized, an evacuation mode occurs which flags an alarm. This mode attempts to lower the pressure of the space to prevent smoke from moving into another space. This is the reverse of the Pressurization mode. Closing the economizer, opening the return-air damper, turning on the power exhaust, and shutting down the indoor fan will decrease pressure in the space. Recovery is automatic when the input is no longer on. A406 (Pressurization Emergency Mode) -- Unit has been placed in the fire pressurization mode by means of the External colrunand for pressurization (Inputs'--)FIRE--+PRES). A407 (Smoke PurEe Emergency Mode) -Unit has been placed in the fire pressurization mode by means of the external colrnnand for pressurization (Inputs'--+FIRE -+PURG). If the smoke purge input on the CEM is energized, a smoke purge mode occurs which flags an alarm. This mode attempts to draw out smoke from the space after the emergency condition. Opening the economizer, closing the return-air damper, and turning on both the power exhaust and indoor fan will evacuate smoke and bring in fresh air. Recovery is automatic when the input is no longer on. T408 (Dirty Air Filter) -- If no dirty filter switch is installed, the switch will read "clean filter" all the thne. Therefore the dirty filter routine runs continuously and diagnoses the input. Because of the different possible times it takes to generate static pressure, this routine waits 2 minutes after the fan starts before the dirty filter switch is monitored. If the dirty filter switch reads "dirty filter" for 2 continuous minutes, an alert is generated. No system action is taken. This is a reminder that it is time to change the filters in the unit. Recovery from this alert is through a clearing of all alarms (manual) or after the dirty filter switch reads clean for 30 continuous seconds (automatic). T313 (Building Static Pressure Above Limit) -- If the unit is configured to use a VFD controlled power exhaust or a modulating power exhaust then a building static pressure lhnit can be 99 Because theDirtyAir Filterswitchcanbeconfigured normallyopened or closed, theswitchmightbeopenorclosed.

These alerts occur when the output of the current sensor (CS) is a constant high value. These alerts reset automatically. If the problem cannot be resolved and the CS board must be replaced, the CS board can be temporarily disabled while securing a replaced board. A CS board is disabled by setting Configuration _'OOL--c(S.A1, (S.A2, (S.B1 or (S.B2 to Disable. MINIMUM OFF TIME VAV (IGV/no gas heat) 2 minutes VAV (VFD/no gas heat) 1 minute 1 minute VAV (IGV/gas heat) 4 minutes 4 minutes VAV (VFD/gas heat) 3 minutes 4 minutes Recovery is manual. Reason for failure may be a broken fan belt, failed fan relay or failed supply fan status switch. T414 (Loss of Colrnnunication with Belflno Actuator) -- The Belimo economizer motor is a digital controlled motor. The (_l_[brtLink TM controls can monitor the status of the motor. If there is a problem, this alert will occur. The control will attempt to close the economizer dampers. If the current sensor board malfunctions or is not properly connected to its assigned digital input, an alert will be generated. It takes 2 to 4 seconds to log the alert. If the alert is logged, it stays for a minhnum of 15 seconds to provide the application a reasonable time to catch the failure. Compressors will be not be inhibited by this failure. Recovery is automatic. Reason for failure may be a faulty current sensor board, incorrect wiring, or a damaged input on the MBB control board. T414 (Belimo Actuator Direction Error) -- This alert occurs when the economizer damper direction switch is in the wrong position. The direction switch should be in the clockwise position and the actuator should be mounted so that the CW face of the actuator is accessible. Correct if necessary. This alert clears automatically.

T420 (R-Wl Jumper Must be Installed to Run Heat in Service Test) -- This alert occurs when a request for a heat output has occurred yet the Wl input is not high. A jumper must be installed between R and Wl when trying to test heat in Service Test. The alert will clear when Service Test is exited or if another Service Test mode is selected. Remove jumper when done using Service Test if the unit is operating with a thermostat. The jumper should only be left in place if the unit is operating with a space temperature sensor. A704 (Staged Gas Leaving Air Temperature Sum Total Failure) -- If all three staged gas thermistors (Temperatures-+AIR. T-+S.GL1-3) fail (the sensor is outside the range of-40 F to 240 F), staged gas will be shut down and this alarm will be generated. Recovery is automatic. Reason for failure may be faulty wiring, faulty thermistors, or damaged inputs on the staged gas control board (SCB). T421 (Thermostat Y2 Input On without Y1 On) -- This alert occurs in Thermostat Mode when Y2 is energized and Y1 is not. Verify thermostat and thermostat wiring. When Y2 turns 100 T705 (Limit Switch Thermistor Failure) -- A failure (the sensor is outside the range of-40 F to 240 F) of this thermistor (Temperatures--)AIR. T--+S.GLM) will cause an alert to occur and a disabling of the limit switch monitoring function for the staged gas control board (SCB). Recovery is automatic. Reason for failure may be due to faulty wiring, a faulty thermistor, or a damaged input on the staged gas control board (SCB). MAJOR SYSTEM VAV BOARD (ECB2) -- The VAV board (which is the same hardware as the ECB1) is used to control the supply fan on VAV units. See Fig. 27. It sends a 4 to 20 mA signal to the VFD based on a supply duct pressure sensor connected to the board. The board also accepts a signal from another pressure sensor that monitors building pressure and controls the operation of the optional modulating power exhaust motors. The board will also be used on CV units with the optional building pressure control feature and modulating power exhaust. This board is also used to control a digitally controlled hot gas bypass solenoid with an integral orifice for use in low load applications. This board is located in the auxiliary control box. Input and output assigmnents are sulmnarized in Table 117.

The control system is composed of several components as listed below. See Fig. 15-23 for typical control and power component schematics. Figures 24 and 25 show the layout of the control box, unit, and thermistor and transducer locations. Factory-Installed STAGED GAS HEAT BOARD (SCB) -- When optional staged gas heat is used on CV and VAV units, the SCB board is installed and controls operation of the gas valves. See Fig. 28. The SCB also provides additional sensors for monitoring of the supply-air temperature. This board is located in the gas heat section of the unit. The inputs and outputs are smrnnarized in Table 118. Components CONTROL EXPANSION MODULE (CEM) -- The optional CEM (also available as an accessory) is used to accept inputs for additional sensors or control sequence switches, including: • smoke control mode field switches • VAV Supply Air Temperature Set Point reset using an external 4 to 20 mA signal • outdoor air CO 2 sensor (for supply duct pressure reset using an eternal 4 to 20 mA signal) • external fan status pressure switch input (CV units) • demand limit sequence proportional signal or discrete switches MAIN BASE BOARD (MBB) -- See Fig 26 The MBB is the center of the (_l_fortLink control system. The MBB contains the major portion of the operating software and controls the operation of the unit. The MBB has 22 inputs and 11 outputs. See Table 115 for the inputs and output assigmnents. The MBB also continuously monitors additional data from the optional ECB1, ECB2, SCB, and CEM boards through the LEN colmnunications port. The MBB also interfaces with the Carrier Comfort Network :R:system through the CCN colmnunications port. The board is located in the main control box. The CEM board is located in the main control box. See Fig. 29. The inputs and outputs are sulmnarized in Table 119. ECONOMIZER BOARD (ECB 1) -- The ECB 1 controls the economizer actuator and the power exhaust fans. The ECB1 operates the economizer motor using a digital cognnunication signal that also provides stares and diagnostics for the economizer motor. See Fig. 27. The ECB1 also controls the operation of the power exhaust motors and provides up to 6 stages of digitally sequenced power exhaust either based on the economizer motor position or the building pressure. The board has 4 inputs and 6 outputs. Additionally, ECB1 provides an output that will send a 4 to 20 mA signal to a field-installed VFD power exhaust accessory. Details can be found in Table 116. The ECB1 board is located in an auxiliary box located at the end of the unit behind the filter access door. The board also contains a second LEN port than can be used with the accessory Navigator TM display. INTEGRATED GAS CONTROL (IGC) -- One IGC is provided with each bank of gas heat exchangers (2 used on the size 020-050 units and 3 on size 051 and 060 units). The IGC controls the direct spark ignition system and monitors the rollout switch, limit switches, and induced-draft motor Hall Effect switch. The IGC is equipped with an LED (lightemitting diode) for diagnostics. See Table 120. COMPRESSOR PROTECTION BOARD (CS) -- This board monitors the status of the compressor by sensing the current flow to the compressors and then provides digital stares signal to the MBB. 101 _[_OT_ FIELO S_Oi< _ ALAR_ CONTACTS _ V0 ?E212 LA_L 8_ _ P[12:,_ ..... -Jl ......

The scrolling marquee display is a 4-key, 4-character, 16-segment LED display as well as an Alarm Stares LED. See Fig. 30. The display is easy to operate using 4 buttons and a group of 11 LEDs that indicate the following menu structures: • Run Status • Service Test • Temperatures • Pressures • Set points • Inputs • Outputs • Configuration • Timeclock • Operating Modes • Alarms SUPPLY FAN -- The size 020 to 050 units are equipped with two 15 x ll-in, forward-curved fans. The size 051 and 060 units have three 15 x 11-in. fans. They are on a colranon shaft and are driven by single belt drive 3-phase motor. The fan is controlled directly by the (_n_folTLink TM controls. VARIABLE FREQUENCY DRIVE (VFD) -- On variable volume units, the supply fan speed is controlled by a 3-phase VFD. The VFD is located in the fan section behind a removable panel as shown in Fig. 24 and 25. The VFD speed is controlled directly by the (_,fortLink controls through a 4 to 20 mA signal based on a supply duct pressure sensor. The inverter has a display, which can be used for service diagnostics, but setup of the supply duct pressure set point and control loop factors is done through the scrolling marquee display. The VFD is powered during normal operation to prevent condensation from forming on the boards during the off mode and is stopped by driving the speed to 0 (by sending a 2 mA signal to the VFD). The A Series units use ABB ACH550 VFDs. The interface wiring for the VFDs is shown in Fig. 31. Terminal designations are shown in Table 121. Through the scrolling marquee the user can access all the inputs and outputs to check on their values and status. Because the unit is equipped with suction pressure transducers and discharge saturation temperature sensors it can also display pressures typically obtained from gages. The control includes a full alarm history, which can be accessed from the display. In addition, through the scrolling marquee the user can access a built-in test routine that can be used at start-up colmnission and to diagnose operational problems with the unit. The scrolling marquee is located in the main control box and is standard on all units.

THERMISTORS AND PRESSURE TRANSDUCERS -The 48/50AJ,AK,AW, AY units are equipped with thermistors and pressure transducers. These units have two thermistors connected to the condenser coil and two pressure transducers that are connected to the low side of the system.

These units have two pressure transducers connected to the low side of the system and two pressure transducers connected to the high side of the system. Factory wired for 4 to 20 mA remote input By using either temperature sensors or transducers, the (_mfortLink controller displays the high and low side pressures and saturation temperatures. A normal gage set is not required. POWER EXHAUSTThe units can be equipped with an optional power exhaust system. The power exhaust fans are forward-curved fans with direct-drive motors. The motors are controlled directly by the (_l_fortLink TM controls through the ECB1 board. On the 48/50A020-050 units there are 4 fans. On the 48/50A051 and 060 units there are 6 fans. The fan sequences are controlled to provide 4 stages on the 48/50A020-050 units and 6 stages on the 48/50A051 and 060 units. There are two control methods. For CV applications the fans can be configured for 2 stages based on adjustable economizer damper positions. For VAV applications and CV units with the building pressure control option, the fans are sequenced to maintain a building pressure set point based on a building pressure transducer. ECONOMIZER MOTOR -- The economizer outside air and return air dampers are gear-driven dampers without linkage. A digitally controlled economizer motor controls their position. The motor position is controlled by the ECB1 board by means of a digital two-way colr_nunication signal. This allows for SMOKE DETECTOR -- The units can be equipped with an optional smoke detector located in the return air. The detector is wired to the (_mfortLink controls and, if activated, will stop the unit by means of a special fire mode. The smoke detector can also be wired to an external alarm system through TB5 terminals 10 and 11. The sensor is located in the return air section behind the filter access door. FILTER STATUS SWITCHThe units can be equipped with an optional filter status switch. The switch measures the pressure drop across the filters and closes when an adjustable pressure set point is exceeded. The sensor is located in the return air section behind the filter access door. RETURN AIR CO 2 SENSOR -- The unit can also be equipped with a return air IAQ CO2 sensor that is used for the demand control ventilation. The sensor is located in the return air section and can be accessed from the filter access door. 123 BOARDADDRESSES -- Eachboardin thesystem hasan address.

If the other methods are to be used, then a field-installed humidity sensor must be installed for outdoor air enthalpy and customer curve control and two humidity sensors must be installed for differential enthalpy. Installation holes are pre-drilled and wire harnesses are installed in every unit for connection of the humidity sensors. The (_mfortLink controls convert the measured humidity into enthalpy, dewpoint, and the humidity changeover curves. 1 = Off CONNECTION TERMINAL STRIPS -- Field conterminal strips are located in the main control box. See and Table 122. MOTORMASTER R:V CONTROL -- For operation below 32 F when an economizer is not used, the units can be equipped with an accessory Motormaster V control, which controls the speed of the stage 1 condenser fans. The Motormaster V control is a 3-phase inverter that controls the speed of the fans based on a pressure transducer connected to the liquid line. On 48/ 50A020-035 units, one fan will be controlled. On 48/50A036060 units, two fans will be controlled. For units equipped with an economizer, there should not be a need for this control because the economizer can provide free cooling using outside air, which will be significantly lower in operating cost. Accessory Control Components E In addition to the factory-installed options, the units can also be equipped with several field-installed accessories that expand the control features of the unit. The following hardware components can be used as accessories. ROOM THERMOSTATS (48/50AJ,AW, A2,A4 UNITS ONLY)The (_mfortLink TM controls support a conventional electro-mechanical or electronic thermostat that uses the Y1, Y2, Wl, W2, and G signals. The control also supports an additional input for an occupied/unoccupied command that is available on some new thermostats. The (_mfortLink controls can be configured to run with multiple stages of capacity which allows up to 6 stages of capacity. Although the unit can be configured for normal 2-stage control, it is recommended that the multi-stage control be used. The room thermostat is connected to TB4. The accessory Motormaster V speed control is a completely self-contained control and is not controlled by the unit's (_mfortLink controller. On 48/50A051 and 060 units with 6 fan motors, the Motormaster control configuration (M..M..) must be set to YES. See page 39. ACCESSORY NAVIGATOR TM DISPLAY -- The accessory handheld Navigator display can be used with the 48/50A series units. See Fig. 34. The Navigator display operates the same way as the scrolling marquee device. The ECB1 and ECB2 boards contain a second LEN port (J3 connection) than can be used with the handheld Navigator display. CONTROL MODULE COMMUNICATIONS SPACE SENSORThe (_mfortLink controls support the use of space temperature sensors. The T55 and T56 sensors and CCN communicating T58 room sensor can be used. The T55 and T56 sensors are connected to TB5 terminal 3, 4, and 5. The T58 sensor is connected to the CCN connections on TB3. When a T55, T56, or T58 sensor is used, the user must install the red jumpers from R to Wl, and W2 on TB4 for the heat function to work correctly. Red LED -- Proper operation of the control boards can be visually checked by looking at the red status LEDs as shown on Fig. 26-29. When operating correctly, the red stares LEDs should blink in unison at a rate of once every 2 seconds. If the red LEDs are not blinking in unison, verify that correct power is being supplied to all modules. Also, be sure that the main base board is supplied with the current software. If necessary, reload current software. If the problem still persists, replace the MBB. A board LED that is lit continuously or blinking at a rate of once per second or faster indicates that the board should be replaced. SPACE CO2 SENSORS -- The (_mfortLink controls also support a CO 2 IAQ sensor that can be located in the space for use in demand ventilation. The sensor must be a 4 to 20 mA sensor and should be connected to TB5 terminal 6 and 7. See Fig. 33 for sensor wiring. ECONOMIZER HUMIDITY CHANGEOVER SENSORS--The (_mfortLink controls support 5 different changeover schemes for the economizer. These are: • • outdoor air enthalpy curves differential enthalpy custom curves (a combination curve and a dry bulb curve). outdoor air dry bulb differential dry bulb + LEN R TB4 C 1 GRD F1 F1 Q@@@ TB3 Y1 CCN Y2 2 3 5 7 9 11 13 15 @@@@@@@@ CCN W1 W2 G TB5 C @@@@@@@@ X @@@@@@@@ 1 3 4 5 6 7 8 2 4 6 8 10 12 14 16 1 3 5 7 9 11 13 15 @@@@@@@@ TB6 @@@@@@@@ 2 4 6 8 10 12 Fig. 32 -- Field Connection Terminal Strips (Main Control Box) 124 14 16 Table 122 -- Field Connection Terminal Strips TERMINAL BOARD I TB-1 - POWER TERMINAL NO.

OVERRIDE Fig. 33 :: _ J5 2' 2 J6 and Space Temperature Sensor Wiring (33ZCT55CO2 and 33ZCT56CO2) Green LED -- The boards also have a green LED, which is the indicator of the operation of the LEN colrnnunications, which is used for colmnunications between the boards. On the MBB board the Local Equipment Network (LEN) LED should always be blinking whenever power is on. All other boards have a LEN LED that will blink whenever power is on and there is colmnunication occumng. IfLEN LED is not blinking, check LEN connections for potential colrnnunication errors (J3 and J4 connectors). A 3-wire sensor bus accomplishes colrnnunication between modules. These 3 wires run in parallel from module to module. It is important when connecting to a CCN colmnunication bus that a color-coding scheme be used for the entire network to simplify the installation. It is recolrnnended that red be used for the signal positive, black for the signal negative and white for the signal ground. Use a similar scheme for cables containing different colored wires. At each system element, the shields of its colrnnunication bus cables must be tied together. If the colrnnunication bus is entirely within one building, the resulting continuous shield must be connected to a ground at one point only. If the colrnnunication bus cable exits from one building and enters another, the shields must be connected to grounds at the lightning suppressor in each building where the cable enters or exits the building (one point per building only). To connect the unit to the network: Yellow LED -- The MBB has one yellow LED. The Carrier Comfort Network R_(CCN) LED will blink during times of network colrnnunication. The other boards do not have a CCN colrnnunications port. CARRIER COMFORT NETWORK INTERFACE -- The 48/50A Series units can be connected to the CCN interface if desired. The colrnnunication bus wiring is a shielded, 3-conductor cable with drain wire and is field supplied and installed. See the Installation Instructions for wiring information. The system elements are connected to the colmnunication bus in a daisy chain arrangement. The positive pin of each system element colmnunication connector must be wired to the positive pins of the system elements on either side of it. This is also required for the negative and signal ground pins of each system element. Wiring connections for CCN should be made at TB3. See Fig. 35. Consult the CCN Contractor's Manual for further information. NOTE: Conductors and drain wire must be 20-AWG (American Wire Gage) minimum stranded, tinned copper. Individual conductors must be insulated with PVC, PVC/ nylon, vinyl, Teflon, or polyethylene. An aluminum/polyester 100% foil shield and an outer jacket of PVC, PVC/nylon, chrome vinyl, or Teflon with a minimum operating temperarare range of-20 C to 60 C is required.

IMPORTANT: A shorted CCN bus cable will prevent some routines from running and may prevent the unit from starting. If abnormal conditions occur, unplug the connector. If conditions return to normal, check the CCN connector and cable. Run new cable if necessary. A short in one section of the bus can cause problems with all system elements on the bus.

Refer to Main Burners section on page 139 for burner removal sequence. If cleaning is required, clean all parts with a wire brush. Reassemble using new hightemperature insulation for sealing. Before performing service or maintenance operations on unit, turn off main power switch to unit. Electrical shock could cause personal iniury. Service Access -- All unit components can be reached through clearly labelled hinged access doors. These doors are not equipped with tiebacks, so if heavy duty servicing is needed, either remove them or prop them open to prevent accidental closure. Each door is held closed with 3 latches. The latches are secured to the unit with a single 1/4-in. - 20 x 1/:-in. long bolt. See Fig. 36. To open, loosen the latch bolt using a 7/16-in. wrench. Pivot the latch so it is not in contact with the door. Open the door. To shut, reverse the above procedure. LATCH BOLT \ NOTE: Disassembly of the top cover may be required under special service circumstances. It is very important that the orientation and position of the top cover be marked on the unit prior to disassembly. This will allow proper replacement of the top cover onto the unit and prevent rainwater from leaking into the unit. Fig. 36 -- Door Latch SPARK GAP .125-1N TO .140-IN SPARK GAP .142-1N. TO .220-1N. IMPORTANT: After servicing is completed, make sure door is closed and relatched properly, and that the latches are tight. Failure to do so can result in water leakage into the evaporator section of the unit. Cleaning -- Inspect unit interior at beginning of each heating and cooling season and as operating conditions require. Remove unit side panels and/or open doors for access to unit interior. MAIN BURNERS -- At the beginning of each heating season, inspect for deterioration or blockage due to corrosion or other causes. Observe the main burner flames and adjust if necessary.

To inspect blower wheel, remove heat exchanger access panel. Shine a flashlight into opening to inspect wheel. If cleaning is required, remove motor and wheel assembly by removing screws holding motor mounting plate to top of combustion fan housing (Fig. 38 and 39). The motor, scroll, and wheel assembly can be removed from the unit. Remove scroll from plate. Remove the blower wheel from the motor shaft and clean with a detergent or solvent. Replace motor and wheel assembly. ROUND TUBE PLATE FIN COIL MA_TENANCE AND CLEANING RECOMMENDATIONS -- Routine cleaning of coil surfaces is essential to maintain proper operation of the unit. Elimination of contamination and removal of harmful residues will greatly increase the life of the coil and extend the life of the unit. The following maintenance and cleaning procedures are recolmnended as part of the routine maintenance activities to extend the life of the coil. Application Harsh chemicals, household bleach or acid or basic cleaners should not be used to clean outdoor or indoor coils of any kind. These cleaners can be very difficult to rinse out of the coil and can accelerate corrosion at the fin!robe interface where dissimilar materials are in contact. If there is dirt below the surface of the coil, use the Totaline environmentally sound coil cleaner as described above. High velocity water from a pressure washer, garden hose, or compressed air should never be used to clean a coil. The force of the water or air jet will bend the fin edges and increase airside pressure drop. Reduced unit performance or nuisance unit shutdown may occur. Tomline Envitvnmenmlly Instructions 3_und (_il ('leaner Application 1. Remove any foreign objects or debris attached to the core face or trapped within the mounting frame and brackets. Remove Surface Loaded Fibers -- Surface loaded fibers or dirt should be removed with a vacuum cleaner. If a vacuum cleaner is not available, a soft non-metallic bristle brash may be used. In either case, the tool should be applied in the direction of the fins. Coil surfaces can be easily damaged (fin edges can be easily bent over and damage to the coating of a protected coil) if the tool is applied across the fins. 2. 3. Put on glasses gloves. Remove cleaner personal protective equipment including safety and/or face shield, waterproof clothing and It is recolmnended to use full coverage clothing. all surface loaded fibers and dirt with a vacuum as described above. Thoroughly wet finned surfaces with clean water and a low velocity garden hose, being careful not to bend fins. 5. Mix Totaline enviromnentally sound coil cleaner in a 21/2 gallon garden sprayer according to the instructions included with the cleaner. The optimum solution temperamre is 100 E 4. NOTE: Use of a water stream, such as a garden hose, against a surface loaded coil will drive the fibers and dirt into the coil. This will make cleaning efforts more difficult. Surface loaded fibers must be completely removed prior to using low velocity clean water rinse. Periodic Clean Water Rinse -- A periodic clean water rinse is very beneficial for coils that are applied in coastal or industrial enviromnents. However, it is very important that the water rinse is made with very low velocity water stream to avoid damaging the fin edges. Monthly cleaning as described below is reconnnended. NOTE: Do NOT USE water in excess of 130 F, as the enzymatic activity will be destroyed. Routine Cleaning of Coil Surfaces -- Monthly cleaning with Totaline :R:enviromnentally sound coil cleaner is essential to extend the life of coils. This cleaner is available from Carrier Replacement parts division as part number P902-0301 for a one gallon container, and part number P902-0305 for a 5 gallon container. It is recolmnended that all coils, including copper robe aluminum fin, pre-coated fin, copper fin, or E-coated coils be cleaned with the Totaline enviromnentally sound coil cleaner as described below. Coil cleaning should be part of the unit's regularly scheduled maintenance procedures to ensure long life 6. Thoroughly apply Totaline enviromnentally cleaner solution to all coil surfaces including robe sheets and coil headers. 7. Hold garden sprayer nozzle close to finned areas and apply cleaner with a vertical, up-and-down motion. Avoid spraying in horizontal pattern to minimize potential for fm damage. 8. Ensure areas. 9.

MICROCHANNEL HEATEXCHANGER (MCHX)CONDENSERCOIL MAINTENANCE AND CLEANING RECOMMENDATIONS Do not apply any chemical cleaners to MCHX condenser coils. These cleaners can accelerate corrosion and damage the coil. Routine cleaning of coil surfaces is essential to maintain proper operation of the unit. Elhnination of contamination and removal of harmful residues will greatly increase the life of the coil and extend the life of the unit. The following steps should be taken to clean MCHX condenser coils: Evaporator (Fig. Start high pressure water sprayer and purge any soap or industrial cleaners from sprayer before cleaning condenser coils. Only clean potable water is authorized for cleaning condenser coils. 4. Clean condenser face by spraying the core steady and uniformly from top to bottom while directing the spray straight toward the core. Do not exceed 900 psig or 45 degree angle. The nozzle must be at least 12 in. from the core face. Reduce pressure and use caution to prevent damage to air centers. Excessive water pressure will fracture air centers and refrigerant tubes. To change fan speeds, change pulleys. To align fan and motor pulleys: 1. Shut offunit power supply. 2. Loosen fan shaft pulley bushing. 3. Slide fan pulley along fan shaft. 4. Make angular aligmnent by loosening mounting plate. 5. Retighten pulley. 6. Return power to the unit. PULLEY PULLEY at Fig. 40- 1. Prior to reassembling the coupling, loosen the 4 bearing mounting bolts, which secure the 2 bearings on either side of the coupling. Remove the drive belts.

The A Series units use ABB VFDs. The interface wiring for the VFDs is shown in Fig. A. The VFD connects through an isolation board to the 4 to 20 mA RCB board. Terminal designations are shown in Table A. Configurations are shown in Table B. On variable air volume units with optional VFD, the supply fan speed is controlled by a 3-phase VFD. The VFD is located in the supply fan section behind a removable panel. The VFD speed is controlled directly by the (_l_fortLink TM controls through a 4 to 20 mA signal based on a supply duct pressure sensor. The VFD has a display, which can be used for service diagnostics, but setup of the building pressure and control loop factors should be done through the scrolling marquee display.

VFD Diagnostics _ HISTORYFor reference, the last three fault codes are stored into parameters 0401, 0412, 0413. For the most recent fault (identified by parameter 0401), the drive stores additional data (in parameters 0402 through 0411) to aid in troubleshooting a problem. For example, a parameter 0404 stores the motor speed at the time of the fault. To clear the fault history (all of Group 04, Fault History parameters), follow these steps: between XI-10 and 2. to AI-1 and AGND. This input a 4 to 20 inN signal.

The expected life span doubles for each 18 F drop in the fan temperature (fan temperature is a function of ambient temperatures and drive loads). Fan failure can be predicted by the increasing noise from fan bearings and the gradual rise in the heat sink temperature in spite of heat sink cleaning. If the drive is operated in a critical part of a process, fan replacement is recolrnnended once these symptolns start appearing. Replacement fans are available from Carrier. To replace the main fan for flame sizes R1 through R4, perform the following (see Fig. D): 1. Remove power from drive. 2. Remove drive cover. 3. For flame sizes R1 and R2, press together the retaining clips on the fan cover and lift.
