Thermostat mounting

Push excess wire back into the wall opening.
Plug wall opening with non-flammable insulation.
Align the 4 tabs on the wallplate with corresponding slots on the back of the thermostat.
Push gently until the thermostat snaps in place.

Installer setup

Follow the procedure below to configure the thermostat to match the installed heating/cooling system, and customize feature operation as desired.

To begin, press and hold the and FAN buttons until the display changes.
Press or t to change settings.
Press NEXT to advance to next function.
Press DONE to exit and save settings.

Special function

Auxiliary heat control (Setup Function 26):
Comfort Setting: The thermostat will prioritize comfort over economy depending on heat pump performance, load conditions and whether the thermostat is calling for the heat pump. Raising the temperature just a few degrees will often activate the auxiliary heat.
Economy Setting: The thermostat will attempt to reach the temperature setting without activating the auxiliary heat. The thermostat will wait to activate the auxiliary heat depending on heat pump performance, load conditions and how many degrees the temperature setting is changed.
