Wiring the Base Plate Terminals

This section describes how to wire the base plate terminals. Use the instructions in this
section and refer to:
Table 2
Burner HVAC. A Fuel Burner typically burns fossil fuel like oil or gas and does
not have a wire used as a reversing valve.
Table 2
Pump HVAC. A Heat Pump configuration always has a wire used to control a
reversing valve.
Refer to the labels you placed on the wires when you removed the existing thermostat.
See page
Some newer Heat Pumps use traditional Fuel Burner wiring schemes without a
Reversing Valve (RV). Therefore, you may have to use a Fuel Burner wiring
Note
scheme to control your Heat Pump. Refer to your Heat Pump manual for wiring
H
details.
You must know the type of Reversing Valve in your heat pump. Refer to your Heat
Pump manual for more information.
