From the Commissioning menu, in the Heat Pump section, you can configure the heat pump. The controller supports up to two stages of heat pump compressors that you can set as follows:

  • The output used by cooling stage 1 is for compressor 1
  • The output used by cooling stage 2 is for compressor 2

The compressors are staged in sequence to maintain the zone temperature setpoint and the reversing valve is indexed to cooling. However, you can also set the Reversing Valve Polarity to switch the reversing valve output for heating or cooling.
