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.
