Installing and Wiring the Thermostat
Heat Pump HVAC
Use the instructions in this section to wire the base plate terminals for heat pump
HVAC on all models of Proliphix thermostats.
To wire the base plate terminals for heat pump HVAC on the Proliphix thermostat,
refer to the labels you placed on the wires when you removed the existing thermostat
(
page 2
). Refer to the procedure in
Fuel Burner HVAC
and use
Table 2
and
Figure 2
to complete the wiring.
Table 2
lists the standard HVAC terminal label and the corresponding Proliphix label
required to support the heat pump application.
Note
You must know the type of Reverse Valve (RVS) in your heat pump. See the user
manual for your heat pump for more information.

For “h” thermostat models only, the 24VAC common must be in the same AC phase as the
24VAC source (RH or RC). If the thermostat is connected to RH only, or RH and RC then C must
be the RH common. If the thermostat is connected to RC only then C must be the RC common.
