Overview
This document is written to guide you through integration of the Trane Communicating
Thermostats into an MS/TP network using the BACnet protocol and managed by a Tracer SC.
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.

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 Designation
Data Sharing – Read Property - B 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
• 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.
BAS-SVP10A-EN 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.

Wiring Requirements for Communicating Thermostats
BACnet networks use a daisy chain configuration. 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
Page 26
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:
• 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.

Product Specifications
Specifications for Communicating Thermostats are as follows.
Table 17. Communicating Thermostat Specifications
Media 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)
Item Details
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.

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
OR
Do Every 5min
If Schedule = On Then
MV13= Occupied
Else
MV13 = Unoccupied
End If
End Do

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.
• 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
• 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.
30 BAS-SVP10A-EN
“Related Documents,” p. 6.)
Page 31
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.
• 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.

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
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).

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).

Page 33
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
Page 34
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
Page 35
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.

When Tracer SC reads the state and text in the left hand column from the BACnet device, it reports
the state and text in the right hand column in the Occupancy Request point.
