Great thermostat but it definitely requires a professional HVAC technician to set it up! Installation was fairly simple. The wires must exactly match the air handler wiring. However, programming the thermostat is a whole different story. Don’t try it yourself unless you want to potentially damage your equipment.
Was very disappointed that the geofence option and the schedule option cannot be used together. On the Nest you can use the schedule and when you leave the house it goes to an Eco setting, when you return home it returns to the schedule setting programed at that time.
This is my first wifi enabled thermostat. I love gadgets. I am very happy with this. It works well and is super easy to use. I did not install it but it took the furnace folks (who recommended it) less than 10 minutes.
