24 VAC must be connected in order for the system fault and emergency heat indicators to operate..
The thermostat has a memory backup that saves the thermostat’s settings in case of a power interruption.
The reset button located under the battery cover can be used to reset the thermostat back to factory defaults. The system settings will also be reset back to defaults.
