Terminal Purpose
PWR Zone sensor power 12VDC input.
D+ Zone sensor data high.
D- Zone sensor data low.
C Zone sensor 12VDC return.
See “Figure 2. Connecting Zone Sensor to Damper
Control Module” on page 7.
Use “Table 2. Terminal Designations” on page 6
for connecting the thermostat wiring to the back
plate terminals.

NOTE: Remember to seal the hole in the wall with
a suitable material to prevent drafts from
entering the zone sensor case. Not doing
so could aect the zone sensor’s internal
temperature and humidity sensors.
NOTE: Use 2-pair, 18AWG unshielded thermostat
cable (eld-provided) for power terminals
(PWR and C). Recommend using 2-pair
22AWG shielded thermostat cable for
communications terminals (D+ and D-) which
will help eliminate any noise interference.
