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.
