Chapter 6 UCMs supported by Tracer Summit systems
56 BMTX-SVN01C-EN
Comm4 UCMs
The UCMs in the following list communicate with BCUs using the
Comm4 communication link. For specific information about the number
of each of these types of UCMs allowed per BCU and per communication
link, refer to Table 5 on page 33.
• Horizon absorption chiller
• Intellipak
• Intellipak CSC
• TUC
• UCP2
• UPCM
• VAV II/III/IV
• VAV wireless receiver
• Voyager rooftop unit interface
Wiring requirements
To establish wiring connections between UCM and the BMTX BCU, refer
to the specifications on wire type, topology, and wiring procedures in
“Comm3/Comm4 wiring” on page 35. For UCM connection points, refer to
literature for the specific UCM.
UCM addresses
UCMs that communicate using Comm4 need to have addresses set with
DIP switches or local displays. Tables with address settings and DIP
switch settings are provided for some of the UCMs in this chapter. As an
alternative, refer to Appendix A for a table that can be used for all DIP
switch settings.
Comm5 UCMs
The Comm5 communication link is Trane’s implementation of the Lon-
Talk
®
protocol. The UCMs shown in Table 8 on page 57 communicate with
BCUs using the Comm5 communication link. The table also shows the
corresponding Tracer Summit objects type. The control mode configura-
tion is given when the object type is dependent on it.
For specific information about the number of each of these types of UCMs
allowed per BCU and per communication link, refer to Table 5 on
page 33.
Wiring requirements
To establish wiring connections between UCM and the BMTX BCU, refer
to the specifications on wire type, topology, and wiring procedures in
“Comm5 wiring” on page 43. For UCM connection points, refer to litera-
ture for the specific UCM.
