Before switching from heating to cooling mode, make sure your temperature control devices are compatible and that you have completed all necessary manual actions related to this mode change. Switching from cooling to heating mode on your thermostat is done through the temperature schedule. In the Home + Control app, go to Settings and select “Schedules”. On the temperature schedule screen, click on the name at the top and select “Heating”. You can now create a new heating schedule or activate one of your heating schedules. Please note that switching from cooling to heating mode will affect all connected thermostats in your home.
