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.

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.
