Product Description The Trane Communicating Thermostats are available for heat pump, rooftop, and fan coil applications. • X13511541010 and -2010 (Heat Pump and Rooftop) These Trane Communicating Thermostats are BACnet MS/TP devices specifically designed for single stage and multi-stage control of heating/cooling equipment such as rooftop and selfcontained units. The products feature an intuitive, menu-driven, back-lit LCD display, which walks users through the programming steps, making the process extremely simple. • X13511543010 (Fan Coil) This Trane Communicating thermostat is specifically designed for fan coil control. The product features a backlit LCD display with dedicated function menu buttons for simple operation. Three additional inputs are also provided for monitoring and / or various advanced functions. All models feature configurable System and Fan button functions to meet a variety of applications. Accurate temperature control is achieved due to the product’s PI proportional control algorithm, which virtually eliminates temperature offset associated with traditional, differential-based thermostats. The Communicating Thermostats contain an SPST auxiliary switch that can be used to control lighting or auxiliary reheat. Three additional inputs are also provided for monitoring and / or various advanced functions. The thermostats are also compatible with the occupancy sensor cover accessories. Thermostats equipped with an occupancy sensor cover provide advanced active occupancy logic, which will automatically switch occupancy levels from Occupied to Unoccupied as required by local activity being present or not. This advanced occupancy functionality provides advantageous energy savings during occupied hours without sacrificing occupant comfort.

Tracer SC link? 6 BAS-SVP10A-EN Summary of BACnet Objects The Building Automation and Control Network (BACnet and ANSI/ASHRAE Standard 135-2004) protocol is a standard that allows building automation systems or components from different manufacturers to share information and control functions. BACnet provides building owners the capability to connect various types of building control systems or subsystems together for many uses. In addition, multiple vendors can use this protocol to share information for monitoring and supervisory control between systems and devices in a multi-vendor interconnected system. The BACnet protocol identifies standard objects (data points) called BACnet objects. Each object has a defined list of properties that provide information about that object. BACnet also defines a number of standard application services that are used to access data and manipulate these objects and provides a client/server communication between devices. Supported BACnet Services The BACnet communicating thermostat meets all requirements for designation as an Application Specific Controller (B-ASC). The BACnet thermostat series supports the following BACnet Interoperability Building Blocks (BIBBs). Table 1. BACnet Interoperability Building Blocks Application Service Data Sharing – Read Property - B Designation DS-RP-B Data Sharing – Read Property Multiple - B DS-RPM-B Data Sharing – Write Property - B DS-WP-B Device Management - Device Communication Control - B DM-DCC-B Device Management – Dynamic Device Binding - B DM-DDB-B Device Management – Dynamic Object Binding - B DM-DOB-B Notes: • The thermostat does not support seqmented requests or responses. • Models X13511541010 and -2010—Time synchronization can be made through a network even if the thermostat does not support the full date. Therefore, the device cannot claim conformance to the DeviceManagement – TimeSynchronization - B (DM-TS-B) service. The device object does not have the Local_Time or Local_Date properties. Default Device Name and Default Device ID The Default Device Name is set to: TStat_EquipType_Trane_MAC where: EquipType is FanCoil, RTU, or HeatPump and MAC is the current MAC address of the device. • The Device Name is changed if you change the device MAC address. • The Device Name and Device ID properties are writable in the Device object. Both properties can be changed from any BACnet network management tool as long as the tool itself can write to these properties. (X13511543010) Fan Coil Models BAS-SVP10A-EN • Default Device ID is set to: 7300MAC where MAC is the current MAC address of the device that you set from the Installer Configuration Parameter menu on the Trane Communicating Thermostat. • The Device ID changes if the device’s MAC address is changed. For example, when a fan coil communicating thermostat with a MAC address of 41 is connected to a network, its default Device Name will be TStat_FanCoil_Trane_41 and its default Device ID will be 730041. 7 Summary of BACnet Objects (X13511541010 and -2010) Rooftop and Heat Pump Models • Default Device ID is set to: 7600MAC where MAC is the current MAC address of the device. • The device ID and the Device Name change if you change the device’s MAC address. For example, when a heat pump communicating thermostat with a MAC address of 63 is connected to a network, its default Device Name will be TStat_HeatPump_Trane_63 and its default Device ID will be 760063.

A daisy chain means that there is only one main cable and every network device is connected directly along its path. Figure 2 illustrates two improper network configurations and the proper daisy chain configuration. Figure 2. Incorrect and correct network configurations BACnet MS/TP Link Wiring BACnet MS/TP link wiring must be field-supplied and installed in compliance with the National Electric Code (NEC) and local codes. BACnet Configuration Requirements • Follow these configuration requirements: • BACnet wiring must use daisy-chain configuration. Maximum length is 4,000 ft (1219 m). • BACnet links are polarity sensitive; consistent wiring polarity must be maintained between devices. • Limit each link to 30 controllers or 60 total controllers per Tracer SC. BACnet Wiring Best Practices The following wiring practices are recommended: • Use 18 AWG, (24 pF/ft. max.), shielded, twisted pair communication wire (Trane purple wire). • Strip no more than 2 in. (5 cm) of the outer conductor of shielded wire. • Avoid sharing 24 Vac power between unit controllers. • Ensure that 24 Vac power supplies are consistently grounded. If grounds are not maintained, intermittent or failed communication could result. • Connect the shield portion of the communication wire at the first unit controller in the link. • Use a Tracer BACnet terminator at each end of the link. For additional best practices, see the Unit Controller Wiring Guide For the Tracer SC™ System Controller (BAS-SVN03x-EN). BAS-SVP10A-EN 25 Wiring Requirements for Communicating Thermostats BACnet Wiring Procedure Follow these steps to connect communication wiring as shown in Figure 3, p. 26. 1. Attach the communication link wiring to the Tracer SC at Link 1 or Link 2. Note: It is not necessary to place the Tracer SC at the end of the of the communication link. 2. Attach the wiring from the first unit controller to the first set of communication terminals on the next unit controller. Note: Some unit controllers have only one set of communication terminals. In that case, attach the wiring to the same set of terminals. 3. Wire and tape shields together at each unit controller between the Tracer SC and the BACnet terminator. 4. Repeat steps 1 through 3 for each unit controller on the link. Note: For more information about the specific unit controller you are wiring, see the Installation Guide for the specific controller. Figure 3. Daisy chain configuration for BACnet wiring Trane BACnet Termination for BACnet Links For correct termination placement, follow these guidelines: 26 • All BACnet links must be properly terminated. Use a Tracer BACnet terminator at each end of the link. • Connect the communication wire shield to the ground terminal of the link termination block at the Tracer SC as shown in Figure 2. The Tracer SC provides the ground for the BACnet/MSTP link. • Tape back the shield at each of the BACnet terminators. • During installation, compile a set of as-built drawings or a map of the communication wire layout. Sketches of the communication layout should feature the BACnet terminators. BAS-SVP10A-EN Figure 4. Terminating BACnet links using BACnet terminators Product Specifications Specifications for Communicating Thermostats are as follows. Table 17. Communicating Thermostat Specifications Item Media Details Twisted pair 22AWG-24 AWG, shielded recommended Characteristic Impedance 100-130 ohms Distributed capacitance Less than 100 pF per meter (30 pF per foot) Maximum length per segment 1200 meters (4000 feet) Note: AWG 18 cable Polarity Polarity sensitive Multi-drop Daisy-chain (no T connections) Terminations Always use Trane BACnet terminators at each end of the link. Maximum number of nodes per segment 30 Baud rate 9600, 19200, 38400, 76800 (Auto detect) Network Adapter The polarity of the connection to the cable is important. From one module to the other it is important that the same colored wire be connected to “plus” or “+” and the other colored wire be connected to the “minus” or ”-“. Important: The Ref terminal should NEVER be used to wire shields. The 2 shields from each feed of the network connection to a thermostat should be wired together in the back of the thermostat and properly protected to prevent any accidental connection to the ground. The joined shield connection should then be grounded at a SINGLE point on the whole segment. More than one ground connection to a shielded wire may induce ground loop noises and affect communication. BAS-SVP10A-EN 27 Wiring Requirements for Communicating Thermostats Communicating Thermostat Status LEDs Table 18 shows the different possibilities with the Status LED behaviour for a BACnet module. Table 18.

Troubleshooting Table 19. Causes and solutions for error condition Error / Trouble Condition Possible Cause Two or more controllers have the same MAC address. Solution Modify each duplicate address to a unique number. Do not exceed the maximum number The MS/TP network has too many of devices and maximum length devices. allowed by the EIA-485 specifications.

The MS/TP cable runs are broken Locate the break and correct wiring MS/TP connections at the module are reversed Respect polarity of the wires on a MS/ TP network. The thermostat does not have power Apply power to the thermostat BAS-SVP10A-EN Additional Information and Considerations This chapter explains some special tips and considerations that apply to the Trane Communicating Thermostats. These tips and considerations are grouped in the following categories: • MS/TP network integration • Objects and parameters • Tracer SC network configuration MS/TP Network Integration Before doing any BACnet integration, make sure to have Trane PICS (Protocol Implementation Conformance Statement). This PICS document lists all the BACnet Services and Object types supported by a device and can be found on the Trane portal. The Trane Communicating Thermostats do not support the Change of Value (COV) service. COV reporting allows an object to send out notices when its Present-Value property is incremented by a pre-defined value. Since this is not supported at the thermostat, you should pay special attention to the polling time settings at the Supervisory Controller and Workstation level when using a graphical interface or an application program to read or write to the BACnet objects. Site Graphics For example, some site graphics might poll every data item linked to the graphic page on a COV basis. If the third party device does not support COV, the graphic interface then relies on a preconfigured polling interval, which is usually in hundredths of milliseconds. Any device containing a monitored object could be subject to network traffic congestion if such a polling interval is used. Trane strongly recommends a polling interval of 5 seconds or more for any graphic interface. This becomes even more critical in area graphics where a single representation might poll many devices. If proper poll rate is not respected, devices may be reported offline by certain front ends by saturating the traffic handling capacity of BACnet MS/TP without COV subscription. Free Programmed Objects or Loops (Supervisory Controllers Other Than Tracer SC) As for the application program, you might want to read and write any MS/TP data on an “If Once” basis or a “Do Every” loop basis instead of reading or writing to a third party device’s object directly in the program. Otherwise, any read or write request will occur at the Supervisory Controller’s program scan rate, which might be in hundredths of milliseconds. This can easily bog down a network as single commands can be sent to all ASC devices down the MS/TP trunks every hundredth of a millisecond. Fan Coils Programs writing to the devices should have a structure similar to the following: If Once Schedule = On then MV13 = Occupied End If If Once Schedule = Off Then MV13 = Unoccupied End If BAS-SVP10A-EN OR Do Every 5min If Schedule = On Then MV13= Occupied Else MV13 = Unoccupied End If End Do 29 Additional Information and Considerations Rooftop and Heat Pump Units Programs writing to the devices should have a structure similar to the following: If Once Schedule = On then MV11 = Occupied End If If Once Schedule = Off Then MV11 = Unoccupied End If OR Do Every 5min If Schedule = On Then MV11= Occupied Else MV11 = Unoccupied End If End Do Retries and Timeouts (Supervisory Controllers Other Than Tracer SC) Another thing to look for in a BACnet integration is the Device object of the Supervisory Controller (and the Operator’s Workstation). This object contains the 2 following required properties: • Retry Timeout The Retry Timeout property specifies the time between re-transmissions if the acknowledgement has not been received. When you are experiencing problems with controllers dropping off-line, increasing this value may help. • Number of APDU Retries; The Number of APDU Retries property specifies the number of times unsuccessful transmissions will be repeated. If the receiving controller has not received the transmission successfully after this many attempts, no further attempts will be made. For example, if one of the thermostats does not reply to a Supervisory Controller (Tracer SC) request, and the Retry Timeout is set to 2000 msec and the Number of APDU Retries is set to 1 (still at the Tracer SC level), then the Tracer SC will send one other request, 2 seconds later. If the MS/ TP device does not reply, it will be considered Off-line by the workstation. So having a Retry Timeout value of 10000 msec and a Number of APDU Retries property set to 3 at the SC level may prevent device from dropping Off-line. These properties should also be changed at the Workstation level since the workstation will likely issue requests to any MS/TP devices when the graphics are used. Objects and Parameters The following items apply to all equipment types. 30 • Each thermostat is delivered from the factory with the default MAC address set at 254. At this value, the BACnet communication is NOT active and the device will not participate in the token pass either. The local LED status (located on the backside of the board) is one short flash only. To enable the BACnet communication, set the local MAC address configuration property of the thermostat to any valid value from 0 to 127 using the Installer Configuration Parameter menuon the Thermostat. (Refer to the Trane Communicating Thermostats for Heat Pump Control User Guide (BAS-SVU10A-EN), Trane Communicating Thermostats for Rooftop Control User Guide (BAS-SVU11A-EN), or the Trane Communicating Thermostats for Fan Coil Control User Guide (BAS-SVU12A-EN) for details.) • All configuration objects are available and can be edited locally from the device itself using the local configuration routine. (See the Communicating Thermostat User Guides mentioned previously in this section or in “Related Documents,” p. 6.) • In its default mode of operation, the device will automatically match its baud rate to the baud rate of the network. Automatic baud rate detection will occur when the MS/TP communication port is initialized (on power up). If the network speed is changed, the device will keep listening at the previously detected speed for 10 minutes before resuming automatic baud rate detection. Re-powering the devices will force immediate auto-detection. BAS-SVP10A-EN Additional Information and Considerations • If the device should go offline, the communicated value from the front-end Tracer SC will be released: – Room Temperature – Outdoor Temperature – Occupancy • Device Name and Device ID properties are writable in BACnet device object. Both properties can be renamed from any BACnet network management tool as long as the tool itself give access to write to these properties. • The BACnet Data Link layer has two key parameters: the device object name and the device object ID. The device object name must be a unique BACnet device object name within the BACnet network (i.e. not just the MS/TP sub-network). The device object ID must also be a unique BACnet device object ID in the entire BACnet network (i.e. not just the MS/TP subnetwork). The following items apply to fan coils only. BAS-SVP10A-EN • Enumeration sets for System Mode MV16 depends on Sequence of Operation (MV15) value upon device discovery. If required enumerations are not present, set MV15 to desired value and rediscover MV16 object. Available enumeration will now reflect required configuration. • Enumeration sets for MV16 depends on Fan Mode Sequence (MV58) value upon device discovery. If required enumerations are not present, set MV58 to desired value and rediscover MV16 object. Available enumeration will now reflect required configuration. • Enumeration sets for MV26 and MV27 depend on Control Type (BV75) value and Pipe Number (MV52) value upon device discovery. If required enumeration is not present, set BV75 and MV52 to desired value and rediscover MV26 and BV27 object. Available enumeration will now reflect required configuration. • To assign manually a Room Temperature (AV7) value, users must first enable the Override mode in the Room Temp Override (BV8) object. • To assign manually a Room Humidity (AV10) value, users must first enable the Override mode in the Room Humidity Override (BV11) object. 31 Additional Information and Considerations Tracer SC Network Configuration You should be aware of these important facts about Communicating Thermostat capabilities in the Tracer SC network. No automatic installation The Trane Communicating Thermostats do not automatically install on the Tracer SC. Custom templates are available and you can select one of these templates (“Template: TStat_RTU_Trane,” p. 40, “Template: TStat_FanCoil_Trane,” p. 36, or “Template: TStat_HeatPump_Trane,” p. 39) to get the unit ready to install. Refer to the Tracer™ SC System Controller Installation and Setup Manual (BAS-SVX31x-EN) for details about using a template to install a Communicating Thermostat on a BACnet link. No priority array Binary, Analog, and Multistate Values do not use a priority array. In order to reliably control these points, they must be controlled by only one source (for example, Area control). If they are being controlled from multiple sources, the most recent source to control the point will be in control. Night Purge disabled A Trane Communicating Thermostat as a member of Area should have Night Purge disabled. Using Night Purge could result in the Heat Cool Mode Request being controlled incorrectly on a transition from Night Purge to another state. You can disable Night Purge for the entire area on the functions page of Area in the Economizer Control section (Figure 5). Figure 5. The Economizer Control section of the Area Functions page Night purge can also be disabled from the members page by checking the box next to certain members and going to actions > edit configuration (Figure 6). 32 BAS-SVP10A-EN Additional Information and Considerations Figure 6. Area members page (actions > edit configuration) Heat only/cool only If the thermostat is configured as cool only, it will not accept its Heat Cool Mode Request to be controlled to any heating mode. The converse applies if the thermostat is configured for heat only, it will not accept its Heat Cool Mode Request to be controlled to any cooling mode. If the point is controlled to an invalid state, it will quickly revert to the previous state. Parameters not supported In the Occupancy frame of the Equipment/Space status page, the following properties will not be displayed: • Last Controlled • Controlled by • Time Remaining These are parameters that the thermostat points do not support. Figure 7. Occupancy section of the Equipment/Space status page BAS-SVP10A-EN 33 Additional Information and Considerations These properties are also shown but not populated on point status pages (Figure 8, p. 34 ). Figure 8. Status section of the Point Status page No active setpoint or heat/cool mode data The Spaces Summary and Equipment Summary pages do not show data for active setpoint or heat/ cool mode as these devices do not have Space Temperature Setpoint Active and Heat Cool Mode Status points ( ). Figure 9. Air Handlers section of the Equipment Status page Discharge air temp requirements The point Discharge Air Temperature on all of these devices only reports data if the respective input is configured as a discharge air sensor and a valid sensor is connected. Inappropriate text on graphic displays In some cases, Binary and Multistate points on a Tracer SC custom graphic display state text that does not match the space or equipment pages. 34 BAS-SVP10A-EN Additional Information and Considerations Outdoor air temperature On the TStat_FanCoil, the point Outdoor Air Temperature is only controlled from a BAS. It is not used in the control sequence of the device. If this value is to be shown on the LCD display on the thermostat, it’s recommended to use global referencing to send the Facility Outdoor Air Temperature to this point. BAS-SVP10A-EN 35 Data Normalization Special data normalization has been applied to various points in the factory loaded equipment templates. This data normalization serves to make a consistent interface to equipment across Tracer SC. This chapter lists special data normalizations for each equipment template. Example: Occupancy Request The following example of the Occupancy Request point in the TStat_FanCoil_Trane template indicates how to interpret the special data normalization. • The point name in Tracer SC is Occupancy Request. • The point name in the BACnet device is Occupancy Command (Multistate Value instance 18 (MV18)). Table 20 and Table 21 show the corresponding Tracer SC and fan coil states. When Tracer SC writes the state in the left hand column to the Occupancy Request point, the BACnet point is controlled to the corresponding state on the right hand column. Table 20.
