Here you go
If your system starts to blow cool air when your Nest thermostat is in Heat mode (or if it blows warm air when its in Cool mode), change the settings for orientation of your heat pump.
The instructions depend on which thermostat you have.
Select the thermostat you have:
Nest Thermostat
- Reset your thermostat. Go to Settings > Factory Reset.
- Begin thermostat setup with the Google Home app again. On the main screen, tap + > Set up a Nest product.
- Re-enter all the wires connected to your thermostat. Double check that you account for any unconfigured wires.
Nest Learning Thermostat and Thermostat E
- On your thermostat, go to Settings.
- Select Equipment.
- Select Continue > Continue.
- Select Heat Pump.
- The Nest Thermostat defaults to an O setting for heat
pumps.
- If the O option is highlighted, select B.
- If the B option is highlighted, select O.
- Test your heating and cooling again to make sure the issue is resolved.
