Low Voltage Wiring
Factory ordered thermostats and zone
sensors are pre-wired with a quick
connecting plug.
1 After installing the cabinet assem-
bly, simply plug the male portion of
thermostat/zone sensor plug into
the female portion of the plug locat-
ed inside the unit’s junction box.
2 Mount the thermostat or zone sen-
sor on the finished drywall.
Thermostat/zone sensor connection is
shown in Figure 13.
Low Voltage Wiring for Field
Provided Thermostats/Zone
Sensors
Ensure that the AC control wiring be-
tween the controls and the unit’s ter-
mination point does not exceed three
(3) ohms/conductor for the length of
the run.
Note: Resistance in excess of 3-ohms
per conductor may cause component
failure due to insufficient AC voltage
supply.
Check all loads and conductors for
grounds, shorts, and mis-wiring.
Use copper conductors unless other-
wise specified.
Do not run the AC low voltage wiring
in the same conduit with the high volt-
age power wiring.
