Description of UCM types
BMTX-SVN01C-EN 73
TCM: Thermostat Control Module
Thermostat Control Modules (TCMs) can provide generic inputs and out-
puts that are controlled directly by Tracer Summit. TCMs can also func-
tion as thermostats for air conditioning units and heat pumps. The TCM
interface provides an isolated Comm3 communication link between the
BCU and each TCM. For specific information about the number of TCMs
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 wiring procedures in
“Comm3/Comm4 wiring procedure” on page 36. Attach the communica-
tion link wiring to the TCM at TB2-1 and TB2-2.
Device addressing
Each UCM must have a unique address that is set using a DIP switch on
the TCM.
• For TCM address DIP switch settings, refer to Table 18 on page 74.
• For the TCM configuration DIP switch settings for S1-7 and S1-8,
refer to Table 19 on page 74.
