How to enable Auto Heat/Cool mode on your ecobee thermostat


It would be nice if you didn't have to change from heat to cool system mode. Can the ecobee3 automatically switch between heat and cool?


You are able to set the mode to Auto which enables the thermostat to switch from heat to cool or from cool to heat automatically.  You will find this option on the thermostat by performing the following actions.

  • Click Menu>System>HVAC>Auto.

If the Auto feature is not there, please perform the following steps from the thermostat:

  • Click Menu>Settings>Installation Settings>Thresholds>Auto Heat/Cool>Enable.
