This was a replacement unit due to a furnace tech blowing out our original, 7 year old unit. Thermostat was exact replacement and works just like original. 99% of time we control via phone app, from anywhere. It also works with home voice commands, google and Alexa.
Easy setup, nice interface. Only thing I did was forget to pull the jumper off for my setup. It turned on both the heat & air! After that, it has been running perfectly.
