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.

Diagnostic Codes (Setup Function 19): When Error Codes are present the home screen of the thermostat will display “SERVICE NEEDED”

and scroll through all active error codes. Setup Function 19 will display a list of the 10 most recent error codes, both active and inactive. The number on the right of the thermostat will show the number of active and inactive error codes saved in the thermostat. To view the error codes press

the up arrow. To clear the list, press and hold both the up and down arrow keys. Active errors can not be cleared; the source of the error must be resolved prior to clearing from the list.
