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.
