Installation Controls

Peer-to-peer communication across controllers is possible even when a building automation system is not present.You do not need to observe polarity for Comm5 communication links.

The controller provides six 0.25-inch quick-connect terminals for the Comm5 communication link connections, as follows:

•Two terminals for communication to the board

•Two terminals for communication from the board to the next unit (daisy chain)

•Two terminals for a connection from the zone sensor back to the controller

Each controller has its own unique address or I.D. number on a Neuron chip. Setting dip switches are not required on the Tracer™ controller.

Tracer Summit Communication Wiring

For Tracer™ ZN-controlled units that will interface with the Trane Tracer Summit® building management system, terminate the communication wiring in the control box at the designated terminals on the board. Reference the unit wiring diagram or submittals.

Ground shields at each Tracer™ ZN controller, taping the opposite end of each shield to prevent any connection between the shield and anther ground. Refer to Trane publication CNT-SVX04A-EN, Tracer ZN.520 Unit Controller - Installation, Operation and Programming Guide, for the communication wiring diagram.

Communication wire must conform to the following specification:

•Shielded twisted pair 18 AWG

•Capacitance 23 (21-25) picofarads (pF) per foot

•Listing/Rating – 300V 150C NEC 725-2 (b) Class 2 Type CL2P

•Trane Part No. 400-20-28 or equivalent, available through Trane BAS Buying Group Accessories catalog.
