With “no-- strip screw” collars, handled access panels, and more we’ve made your unit easy to install, easy to maintain and easy to use. Easy to install: All WeatherMasterr units are field-- convertible to horizontal air flow; no special adapter curbs or kits are necessary. Convertible airflow design makes it easy to adjust to unexpected job-- site complications. Lighter units make easy replacement. Carrier 3-- 10 ton 48HC rooftops fit on existing Carrier curbs dating back to 1989. Also, our large control box gives you room to work and room to mount Carrier accessory controls. Easy to maintain: Easy access handles by Carrier provide quick and easy access to all normally serviced components. Our “no-- strip” screw system has superior holding power and guides screws into position while preventing the screw from stripping the unit’s metal. Take accurate pressure readings by reading condenser pressure with panels on. Simply remove the black, composite plug, route your gauge line(s) through the hole, and connect them to the refrigeration service valve(s). Now, you can take refrigeration system pressure readings without affecting the condenser airflow. Easy to use: The newly designed, master terminal board by Carrier puts all your connections and troubleshooting points in one convenient place, standard. Most low voltage connections are made to the same board and make it easy to find what you’re looking for and easy to access it. Carrier rooftops have high and low pressure switches, a filter drier, and 2” (51mm) filters standard. the environmentally sound refrigerant 2 FEATURES AND BENEFITS S Single-- stage cooling capacity control on 04 to 07 models S Two-- stage cooling capacity control on 08 to 12 models S SEER up to 15.6 S EER up to 13.0 S IEER’s up to 13.0 S Exclusive non-- corrosive composite condensate pan in accordance with ASHRAE 62 Standard, sloping design; side or center drain S Gas efficiencies up to 82% S Induced draft combustion design S Pre-- painted exterior panels and primer-- coated interior panels tested to 500 hours salt spray protection S TXV refrigerant metering system on each circuit S Fully insulated cabinet S Exclusive IGC solid-- state control for on-- board diagnostics with LED error code designation, burner control logic and energy saving indoor fan motor delay S Dedicated 3-- 5 ton “Low NOx” models available that meet California Air Quality Management NOx requirement of 40 nangram/joule or less.

They bring in fresh, outside air for ventilation; and provide cool, outside air to cool your building. This is the preferred method of low-- ambient cooling. When coupled to CO2 sensors, economizers can provide even more savings by coupling the ventilation air to only that amount required. Superior internal building pressure control. This field-- installed accessory may eliminate the need for costly, external pressure control fans. 48HC Economizers are available, installed and tested by the factory, with either enthalpy or dry-- bulb temperature inputs. There are also models for electromechanical as well as direct digital controllers. Additional sensors are available as accessories to optimize the economizers. Economizers include gravity controlled, barometric relief equalizes building pressure and ambient air pressures. This can be a cast effective solution to prevent building pressurization. CO2 Sensor Improves productivity and saves money by working with the economizer to intake only the correct amount of outside air for ventilation. As occupants fill your building, the CO2 sensor detects their presence through increasing CO2 levels, and opens the economizer appropriately. PremierLink, DDC Controller This CCN controller regulates your rooftop’s performance to tighter tolerances and expanded limits, as well as facilitates zoning systems and digital accessories. It also unites your Carrier HVAC equipment together on one, coherent CCN network. The PremierLink can be factory-- installed, or easily field-- installed. RTU Open, Multi--Protocol Controller Connect the rooftop to an existing BAS without needing complicated translators or adapter modules using the RTU Open controller. This new controller speaks the 4 most common building automation system languages (Bacnet, Modbus, N2, and Lonworks). Use this controller when you have an existing BAS. Besides the 4 protocols, it also communicates with a Carrier Open system (I-- Vu and VVT). Time Guard II Control Circuit When the occupants leave, the CO2 levels decrease, and the sensor appropriately closes the economizer. This intelligent control of the ventilation air, called Demand Control Ventilation (DCV) reduces the overall load on the rooftop, saving money. This accessory protects your compressor by preventing short-- cycling in the event of some other failure, prevents the compressor from restarting for 30 seconds after stopping. Not required with PremierLink, RTU Open, or authorized commercial thermostats. Smoke Detectors Motorized 2--Position Damper Trust the experts. Smoke detectors make your application safer and your job easier. Carrier smoke detectors immediately shut down the rooftop unit when smoke is detected. They are available, installed by the factory, for supply air, return air, or both. The new Carrier 2-- position, motorized outdoor air damper admits up to 100% outside air. Using reliable, gear-- driven technology, the 2-- position damper opens to allow ventilation air and closes when the rooftop stops, stopping unwanted infiltration. Louvered Hail Guards Manual OA Damper Sleek, louvered panels protect the condenser coil from hail damage, foreign objects, and incidental contact. Manual outdoor air dampers are an economical way to bring in ventilation air. The dampers are available in 25% and 50% versions. Convenience Outlet (powered or un--powered) Reduce service and/or installation costs by including a convenience outlet in your specification. Carrier will install this service feature at our factory. Provides a convenient, 15 amp, 115v GFCI receptacle with “Wet in Use” cover. The “powered” option allows the installer to power the outlet from the line side of the disconnect or load side as required by code. The “unpowered” option is to be powered from a separate 115/120v power source. Hinged Access Panels Allows access to unit’s major components with specifically designed hinged access panels. Panels are: filter, control box, fan motor and compressor. Non--fused Disconnect This OSHA-- compliant, factory-- installed, safety switch allows a service technician to locally secure power to the rooftop. 6 FACTORY OPTIONS AND/OR ACCESSORIES (CON’T) Motormaster Head Pressure Controller Optional Stainless Steel Heat Exchanger The Motormaster motor controller is a low ambient, head pressure controller kit that is designed to maintain the unit’s condenser head pressure during periods of low ambient cooling operation. This device should be used as an alternative to economizer free cooling not when economizer usage is either not appropriate or desired. The Motormaster will either cycle the outdoor-- fan motors or operate them at reduced speed to maintain the unit operation, depending on the model. The stainless steel heat exchanger option provides the tubular heat exchanger be made out of a minimum 20 gauge type 409 stainless steel for applications where the mixed air to the heat exchanger is expected to drop below 45_F (7_C). Stainless steel may be specified on applications where the presence of airborne contaminants require its use (applications such as paper mills) or in area with very high outdoor humidity that may result in severe condensation in the heat exchanger during cooling operation. The winter start kit by Carrier extends the low ambient limit of your rooftop to 25_F (-- 4_C). The kit bypasses the low pressure switch, preventing nuisance tripping of the low pressure switch. Other low ambient precautions may still be prudent. Propane Heating Convert your gas heat rooftop from standard natural gas operation to Propane using this field-- installed kit. High Altitude Heating High altitudes have less oxygen, which means heat exchangers need less fuel. The new gas orifices in this field-- installed kit make the necessary adjustment for high altitude applications. They restore the optimal fuel to air mixture and maintain healthy combustion at altitudes above 2000 ft (610m). Kits may not be required in all areas. Flue Discharge Deflector The flue discharge deflector is a useful accessory when flue gas recirculation is a concern. By venting the flue discharge upwards, the deflector minimizes the chance for a neighboring unit to intake the flue exhaust. Flue Discharge Heat Shield The flue discharge heat shield keeps people from touching the rooftop unit’s potentially hot flue discharge. This is especially useful for ground level applications, where more, untrained people could have access to the unit’s exterior. Alternate Motors and Drives Some applications need larger horsepower motors, some need more airflow, and some need both. Regardless of the case, your Carrier expert has a factory installed combination to meet your application. A wide selection of motors and pulleys (drives) are available, factory installed, to handle nearly any application. Thru--the--Base Connections Thru-- the-- base connections, available as either an accessory or as a factory option, are necessary to ensure proper connection and seal when routing wire and piping through the rooftop’s basepan and curb. These couplings eliminate roof penetration and should be considered for gas lines, main power lines, as well as control power. 7 48HC Winter Start Kit TABLE 2 – AHRI COOLING RATING TABLE 1-- STAGE COOLING UNIT COOLING STAGES NOM.

It is possible to provide cooling at lower outdoor ambient temperatures by using less outside air, economizers, and/or accessory low ambient kits. Economizers reduce operating expenses and compressor run time by providing a free source of cooling and a means of ventilation to match application changing needs. In fact, they should be considered for most applications. Also, consider the various economizer control methods and their benefits, as well as sensors required to accomplish your application goals. Please contact your local Carrier representative for assistance. 48HC Max operating ambient temp (cooling): The maximum operating ambient temperature for cooling mode is 125_F (52_C). While cooling operation above 125_F (52_C) may be possible, it could cause either a reduction in performance, reliability, or a protective action by the unit’s internal safety devices. Min mixed air temp (heating): Using the factory settings, the minimum temperatures for the mixed air (the combined temperature of the warm return air and the cold outdoor air) entering the dimpled, gas heat exchangers are: Aluminized 50_F (10_C) continuous 45_F (7_C) intermittent Stainless Steel 40_F (4_C) continuous 35_F (2_C) intermittent Operating at lower mixed-- air temperatures may be possible, if a field-- supplied, outdoor air thermostat initiates both heat stages when the temperature is less than the minimum temperatures listed above. Please contact your local Carrier representative for assistance. Min and max airflow (heating and cooling): To maintain safe and reliable operation of your rooftop, operate within the heating airflow limits during heating mode and cooling airflow limits during cooling mode. Operating above the max may cause blow-- off, undesired airflow noise, or airflow related problems with the rooftop unit. Operating below the min may cause problems with coil freeze-- up and unsafe heating operation. Heating and cooling limitations differ when evaluating operating CFM, the minimum value is the HIGHER of the cooling and heating minimum CFM values published in Table 7 and the maximum value is the LOWER of the cooling and heating minimum values published in Table 7. Heating--to--cooling changeover: Your unit will automatically change from heating to cooling mode when using a thermostat with an auto-- change-- over feature. Airflow: All units are draw-- though in cooling mode and blow-- through in heating mode. Motor limits, break horsepower (BHP): Due to internal design of Carrier units, the air path, and specially designed motors, the full horsepower (maximum continuous BHP) band, as listed in Table 8 and 10, can be used with the utmost confidence. There is no need for extra safety factors, as Carrier motors are designed and rigorously tested to use the entire, listed BHP range without either nuisance tripping or premature motor failure. Propane heating: Propane has different physical qualities than natural gas. As a result, Propane requires different fuel to air mixture. To optimize the fuel/air mixture for Propane, Carrier sells different burner orifices in an easy to install accessory kit. To select the correct burner orifices or determine the heat capacity for an Propane application, use either the selection software, or the unit’s service manual. High altitude heating: High altitudes have less oxygen, which affects the fuel/air mixture in heat exchangers. In order to maintain a proper fuel/air mixture, heat exchangers operating in altitudes above 2000 ft (610 m) require different orifices. To select the correct burner orifices or determine the heat capacity for a high altitude application, use either the selection software, or the unit’s service manual. High altitudes have less oxygen, which means heat exchangers need less fuel. The new gas orifices in this field-- installed kit make the necessary adjustment for high altitude applications. They restore the optimal fuel to air mixture and maintain healthy combustion on altitudes above 2000 ft (610 m). NOTE: Typical natural gas heating value ranges from 975 to 1050 Btu/ft3 at sea level nationally. The heating value goes down approximately 1.7% per every thousand feet elevation. Standard factory orifices can typically be used up to 2000 ft (610m) elevation without any operational issues. NOTE: For installations in Canada, the input rating should be derated by 10% for altitudes from 2000 ft (610m)to 4500 ft (1372m) above sea level. 26 Sizing a rooftop Low ambient applications Bigger isn’t necessarily better. While an air conditioner needs to have enough capacity to meet the design loads, it doesn’t need excess capacity. In fact, excess capacity typically results in very poor part load performance and humidity control. The optional Carrier economizer can adequately cool your space by bringing in fresh, cool outside air. In fact, when so equipped, accessory low-- ambient kit may not be necessary. In low ambient conditions, unless the outdoor air is excessively humid or contaminated, economizer-- based “free cooling” is the preferred less costly and energy conscious method. Using higher design temperatures than ASHRAE recommends for your location, adding “safety factors” to the calculated load, are all signs of oversizing air conditioners. Oversizing the air conditioner leads to poor humidity control, reduced efficiency, higher utility bills, larger indoor temperature swings, excessive noise, and increased wear and tear on the air conditioner. Rather than oversizing an air conditioner, engineers should “right-- size” or even slightly undersize air conditioners. Correctly sizing an air conditioner controls humidity better; promotes efficiency; reduces utility bills; extends equipment life, and maintains even, comfortable temperatures. Please contact your local Carrier representative for assistance. In low ambient applications where outside air might not be desired (such as contaminated or excessively humid outdoor environments), your Carrier rooftop can operate to ambient temperatures down to - 20_F (-- 29_C) using the recommended accessory Motormaster low ambient controller. 27 48HC APPLICATION DATA (cont.) SELECTION PROCEDURE (WITH 48HC*A07 EXAMPLE)1 I. 48HC II. Determine cooling and heating loads. Given: Mixed air dry bulb 80_F (27_C) Mixed air wet bulb 67_F (19_C) Ambient dry bulb 95_F (35_C) 73.6 MBH TCLoad SHCLoad 53.3 MBH Vertical supply air 2100 CFM Heating load 85.0 MBH External static pressure 0.67 in. wg Electrical characteristics 230-- 3-- 60 Make an initial guess at cooling tons. Refrig. tons = TCLoad / 12 MBH per ton Refrig. tons = 72.0 / 12 = 6.0 tons In this case, start by looking at the 48HC**07. III. Look up the rooftop’s TC and SHC. Table 15 shows that, at the application’s supply air CFM, mixed air and ambient temperatures, the 48HC*A07 supplies: TC = 73.6 MBH2 SHC = 53.3 MBH2 IV. Local code requires an economizer for any unit with TC greater than 65.0 MBH. VIII. Calculate the total static pressure. External static pressure Sum of FIOP / Accessory static 0.67 in. wg +0.13 in. wg Total Static Pressure 0.80 in. wg IX. Look up the indoor fan RPM & BHP. Table 27 shows, at 2100 CFM & ESP= 0.8, RPM = 712 & BHP = 1.17 X. Convert BHP (Step VIII) into fan motor heat. Fan motor heat = 2.546* BHP/Motor Eff.4 Fan motor heat = 3.7 MBH XI. Calculate RTU heating capacity. Building heating load Fan motor heat Required heating capacity XII. Select a gas heater. 85.0 MBH - 3.7 MBH 81.3 MBH Table 4 shows the heating capacities of the 48HCEA07 = 103.0 MBH. Select the 48HCEA07 Calculate the building latent heat load. LCLoad = TCLoad - SHCLoad LCLoad = 72.0 MBH - 54.0 MBH = 18.0 MBH V. VII. Select factory options (FIOP) XIII. Determine electrical requirements. Table 50 shows the MCA and Breaker Size of a 48HC*A07 (without convenience outlet) as: MCA = 32.0 amps & MOCP = 50.0 amps Min. disconnect size: FLA = 31.0 & LRA = 148. Calculate RTU latent heat capacity. LC = TC - SHC LC = 73.6 MBH - 53.3 MBH = 20.3 MBH VI. Compare RTU capacities to loads.3 Compare the rooftop’s SHC and LC to the building’s sensible and latent heat loads.

Selection software by Carrier saves time by performing many of the steps above. Contact your Carrier sales representative for assistance. 2. Unit ratings are gross capacities and do not include the effect of evaporator fan motor heat. See Step XI. for determining amount of evaporator fan motor heat to subtract from total and sensible capacities to obtain net cooling and net sensible capacities. 3. Selecting a unit with a SHC slightly lower than the SHCLoad is often better than oversizing. Slightly lower SHC’s will help control indoor humidity, and prevent temperature swings. 4. Indoor fan motor efficiency is available in Table 41. Use the decimal form in the equation, eg. 80% = .8. 28 48HC*A04 58 62 900 Cfm EA (wb) 67 72 78 58 62 1050 Cfm EA (wb) 67 72 78 58 62 1200 Cfm EA (wb) 67 72 78 58 62 1350 Cfm EA (wb) 67 72 78 58 62

0.51 0.56 0.60 General fan performance notes: 1. Interpolation is permissible. Do not extrapolate. 2. External static pressure is the static pressure difference between the return duct and the supply duct plus the static pressure caused by any FIOPs or accessories. 3. Tabular data accounts for pressure loss due to clean filters, unit casing, and wet coils. Factory options and accessories may add static pressure losses, as shown in Table 19. Selection software is available, through your salesperson, to help you select the best motor/drive combination for your application. 4. The Fan Performance tables offer motor/drive recommendations. In cases when two motor/drive combinations would work, Carrier recommended the lower horsepower option. 5. For information on the electrical properties of Carrier motors, please see the Electrical information section of this book. 6. For more information on the performance limits of Carrier motors, see the application data section of this book. 7. The EPACT (Energy Policy Act of 1992) regulates energy requirements for specific types of indoor fan motors. Motors regulated by EPACT include any general purpose, T-- frame (three-- digit, 143 and larger), single-- speed, foot mounted, polyphase, squirrel cage induction motors of NEMA (National Electrical Manufacturers Association) design A and B, manufactured for use in the United States. Ranging from 1 to 200 Hp, these continuous-- duty motors operate on 230 and 460 volt, 60 Hz power. If a motor does not fit into these specifications, the motor does not have to be replaced by an EPACT compliant energy-- efficient motor. Variable-- speed motors are exempt from EPACT compliance requirements. Therefore, the indoor fan motors for Carrier 48HC04-- 12 units are exempt from these requirements. 36 FAN PERFORMANCE (BELT DRIVE) CFM 900 975 1050 1125 1200 1275 1350 1425 1500 CFM 900 975 1050 1125 1200 1275 1350 1425 1500 RPM 0.2 582 606 630 655 681 708 735 762 790 RPM 1.2 1086 1101 1117 1133 1150 1168 1186 1204 1223 3 PHASE BHP RPM 0.14 0.16 0.18 0.21 0.24 0.27 0.31 0.35 0.40 715 735 756 778 800 823 847 871 896 BHP RPM 0.79 0.82 0.86 0.90 0.95 1.00 1.05 1.11 1.18 1159 1174 1189 1204 1221 1237 1255 1272 1291 0.4 1.4 3 TON HORIZONTAL SUPPLY Available External Static Pressure (in. wg) 0.6 0.8 BHP RPM BHP RPM BHP RPM 0.24 0.26 0.29 0.32 0.35 0.39 0.43 0.48 0.53 0.48 0.51 0.55 0.58 0.63 0.67 0.72 0.77 0.83 1007 1023 1040 1057 1074 1093 1112 1131 1151 BHP RPM 1.33 1.37 1.41 1.46 1.51 1.57 1.63 1.70 1.77 1354 1367 1381 1395 1410 1425 1441 1457 1473 825 843 862 882 902 923 945 967 990 0.35 0.38 0.41 0.45 0.48 0.53 0.57 0.62 0.67 921 938 955 974 992 1012 1032 1053 1074 Available External Static Pressure (in. wg) 1.6 1.8 BHP RPM BHP RPM 0.96 0.99 1.03 1.08 1.13 1.18 1.24 1.30 1.36 1228 1242 1256 1271 1287 1303 1320 1337 1355 1.14 1.18 1.22 1.26 1.31 1.37 1.43 1.49 1.56 1293 1306 1320 1335 1350 1365 1382 1398 1415 1.0 BHP 0.63 0.66 0.70 0.74 0.78 0.83 0.88 0.94 1.00 2.0 BHP 1.53 1.57 1.62 1.67 1.72 1.78 1.84 1.91 1.99 NOTE: For more information, see General Fan Performance Notes.

C08577 Fig. 20 -- 2--Stage Cooling Typical Power Diagram 58 59 Fig. 21 -- 1--Stage Typical Wiring Diagram 48HC C08524 60 Fig. 22 -- 2--Stage Typical Wiring Diagram 48HC C08578 SEQUENCE OF OPERATION The sequence below describes the sequence of operation for an electro-- mechanical unit with and without a factory installed EconoMi$ert IV (called “economizer” in this sequence). For information regarding a direct digital controller, see the start-- up, operations, and troubleshooting manual for the applicable controller. Electro--mechanical units with no economizer Cooling — When the thermostat calls for cooling, terminals G and Y1 are energized. As a result, the indoor-- fan contactor (IFC) and the compressor contactor (C1) are energized, causing the indoor-- an motor (IFM), compressor #1, and outdoor fan to start. If the unit has 2 stages of cooling, the thermostat will additionally energize Y2. The Y2 signal will energize compressor contactor #2 (C2), causing compressor #2 to start. Regardless of the number of stages, the outdoor-- fan motor runs continuously while unit is cooling. Heating NOTE: WeatherMasterR (48HC) units have either 1 or 2 stages of gas heat. When the thermostat calls for heating, power is sent to W on the Integrated Gas Controller (IGC) board. An LED (light-- emitting diode) on the IGC board turns on and remains on during normal operation. A check is made to ensure that the rollout switch and limit switch are closed. If the check was successful, the induced-- draft motor is energized, and when its speed is satisfactory, as proven by the “hall effect” sensor, the ignition activation period begins. The burners will ignite within 5 seconds. If the burners do not light, there is a 22-- second delay before another 5-- second attempt. This sequence is repeated for 15 minutes or until the burners light. If, after the 15 minutes, the burners still have not lit, heating is locked out. To reset the control, break 24-- v power to the thermostat. When ignition occurs, the IGC board will continue to monitor the condition of the rollout switch, the limit switches, the “hall effect” sensor, as well as the flame sensor. 45 seconds after ignition occurs, assuming the unit is controlled through a room thermostat set for fan auto, the indoor-- fan motor will energize (and the outdoor-- air dampers will open to their minimum position). If, for some reason, the over-- temperature limit opens prior to the start of the indoor fan blower, the unit will shorten the 45-- second delay to 5 seconds less than the time from initiation of heat to when the limit tripped. Gas will not be interrupted to the burners and heating will continue. Once the fan-- on delay has been modified, it will not change back to 45 seconds until power is reset to the control. On units with 2 stages of heat, when additional heat is required, W2 closes and initiates power to the second stage of the main gas valve. When the thermostat is satisfied, W1 and W2 open and the gas valve closes, interrupting the flow of gas to the main burners. If the call for W1 lasted less than 1 minute, the heating cycle will not terminate until 1 minute after W1 became active. If the unit is controlled through a room thermostat set for fan auto, the indoor-- fan motor will continue to operate for an additional 45 seconds then stop. If the over-- temperature limit opens after the indoor motor is stopped, but within 10 minutes of W1 becoming inactive, on the next cycle the time will be extended by 15 seconds. The maximum delay is 3 minutes. Once modified, the fan off delay will not change back to 45 seconds unless power is reset to the control. A LED indicator is provided on the IGC to monitor operation. Electro--mechanical units with an economizer Cooling — When free cooling is not available, the compressors will be controlled by the zone thermostat. When free cooling is available, the outdoor-- air damper is modulated by the EconoMi$er IV control to provide a 50_F (10_C) to 55_F (13_C) mixed-- air temperature into the zone. As the mixed air temperature fluctuates above 55_F (13_C)or below 50_F (10_C) dampers will be modulated (open or close) to bring the mixed-- air temperature back within control. If mechanical cooling is utilized with free cooling, the outdoor-- air damper will maintain its current position at the time the compressor is started. If the increase in cooling capacity causes the mixed-- air temperature to drop below 45_F (7_C), then the outdoor-- air damper position will be decreased to the minimum position. If the mixed-- air temperature continues to fall, the outdoor-- air damper will close. Control returns to normal once the mixed-- air temperature rises above 48_F (9_C). The power exhaust fans will be energized and de-- energized, if installed, as the outdoor-- air damper opens and closes. If field-- installed accessory CO2 sensors are connected to the EconoMi$er IV control, a demand controlled ventilation strategy will begin to operate. As the CO2 level in the zone increases above the CO2 setpoint, the minimum position of the damper will be increased proportionally. As the CO2 level decreases because of the increase in fresh air, the outdoor-- air damper will be proportionally closed. For EconoMi$er IV operation, there must be a thermostat call for the fan (G). If the unit is occupied and the fan is on, the damper will operate at minimum position. Otherwise, the damper will be closed. When the EconoMi$er IV control is in the occupied mode and a call for cooling exists (Y1 on the thermostat), the control will first check for indoor fan operation. If the fan is not on, then cooling will not be activated. If the fan is on, then the control will open the EconoMi$er IV damper to the minimum position. 61 48HC General 48HC SEQUENCE OF OPERATION (cont.) On the initial power to the EconoMi$er IV control, it will take the damper up to 2 1/2 minutes before it begins to position itself. After the initial power-- up, further changes in damper position can take up to 30 seconds to initiate. Damper movement from full closed to full open (or vice versa) will take between 1 1/2 and 2 1/2 minutes. If free cooling can be used as determined from the appropriate changeover command (switch, dry bulb, enthalpy curve, differential dry bulb, or differential enthalpy), then the control will modulate the dampers open to maintain the mixed-- air temperature setpoint at 50_F (10_C) to 55_F (13_C). If there is a further demand for cooling (cooling second stage - Y2 is energized), then the control will bring on compressor stage 1 to maintain the mixed-- air temperature setpoint. The EconoMi$er IV damper will be open at maximum position. EconoMi$er IV operation is limited to a single compressor. Heating The sequence of operation for the heating is the same as an electromechanical unit with no economizer. The only difference is how the economizer acts. The economizer will stay at the Economizer Minimum Position while the evaporator fan is operating. The outdoor-- air damper is closed when the indoor fan is not operating. 62 GUIDE SPECIFICATIONS -- 48HC**04--12 Note about this specification: This specification is in the “Masterformat” as published by the Construction Specification Institute.
