Thermostat was installed by HVAC System technician when I was not at home. Instructions were misplaced. Took two calls to figure out how to calibrate program. Going through menu could be simplified by allowing programming with a smart phone. Once programmed, thermostat has great features. I have elected to manually adjust temperature because we are either at the house or away for days. Geofencing is a good idea but not if we are running errands nearby, therefore I did not setup geofencing.
