Chapter 6 UCMs supported by Tracer Summit systems

PCM: Programmable control module
Programmable control modules (PCMs) allow Tracer Summit to monitor
and control HVAC equipment such as air handlers, chillers, pumps, and
generic loads. You can also use PCMs to add generic analog and binary
inputs and outputs to Tracer Summit.
You can connect PCMs to any isolated Comm3 UCM communication link
on TB2. The link provides a serial communication interface between the
BCU and each PCM in the system. For specific information about the
number of PCMs allowed per BCU and per communication link, refer to
Table 5 on page 33.
Wiring requirements
To establish wiring connections between the UCM and the BMTX BCU,
refer to the specifications on wire type, topology, and wire procedures in “”
on page 34.
Device addressing
Each UCM must have a unique address on each link. On the PCM, the
address is set with the S2 address DIP switches. For PCM DIP switch set-
tings, refer to Table 16.
