Table 2
lists the standard HVAC terminal label required to support the single-stage

Note
H
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
scheme to control your Heat Pump. Refer to your Heat Pump manual for wiring
details.
You must know the type of Reversing Valve (reverse for cooling or reverse for
heating) in your heat pump. Refer to your Heat Pump manual for more
information.
