This works fantastic. I had installed at our lake house. I can leave it at an economical setting, and when i am going i getting ready to head there. i just adjust thermostat on my phone to a comfortable setting when i arrive.
Had a Honeywell thermostat at our previous home. This is a newer model and is much easier to program and was a breeze to initially setup and connect to the internet.
In general, this is a very good thermostat except for one issue that does not have or allow a mode setting to automatically change for cold and warm settings when the temperature changes from summer to winter.
