VAV wireless receiver interface
The variable air volume (VAV) wireless receiver allows a Tracer Summit
system to monitor wireless thermostats. You can connect the wireless
receiver to any Comm4 communication link on TB3 or TB4. The link pro-
vides a serial communication interface between the BCU and each wire-
less receiver in the system. For specific information about the number of
wireless receivers 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 BCU, refer to
the specifications on wire type, topology, and wiring procedures in
“Comm3/Comm4 wiring” on page 35. The wireless receiver ships from the
factory with wire terminations completed inside the receiver. The wire
protruding through conduit on the back side of the unit is ready to be
spliced.
Device addressing
Each UCM must have a unique address on each link. Wireless receivers
can have an address from 1 through 31. The address is set with the DIP
switches located on the side of the wireless receiver. For VAV wireless
receiver DIP switch settings, refer to Table 23 on page 84.
