Heating or Cooling Doesn’t Turn On When
the Set Point is Above or Below the Room
Temperature
To prevent damaging the compressor, the
thermostat inserts a delay when cycling the
compressor. If you think the system should be
on and it’s not, then change the set point to be
2 degrees beyond the current set point and wait
5 minutes to see if the system turns on. If not,
contact a local HVAC professional.
Heat Pump is “Cooling When it Should
be Heating” or “Heating When it Should
be Cooling”
Because both types of heat pump reversing valves
share a single terminal on your thermostat back
plate, you need to be sure you have the thermostat
configured for the correct wire. Try switching the
O/B configuration setting through your online
account. Contact a local HVAC professional for
further help with this issue. This troubleshooting
also applies to a heat pump that is heating when it
should be cooling.
