had 2 of these installed in my home and neither of them would work. they would not start the furnace. finally bought a different model and it fired right up. this model is junk, plain and simple. I would connect to the wifi, but would never start the furnace no matter what the techs did with the wiring.
Contractor set it up for me with date and time. Easy to use once set up for me. I am not sure what EM Heat means... the APP was a bit difficult to install but after 3 attempts I was able to install. CS out of country and very difficult to reach. One problem with APP is it doesn’t remember your sign in data. In the middle of the night you need to keyboard in the information to change temperature... easier to get Out of bed ...ugh.
I believe I will like this thermostat much better than my previous one. However. I set up a schedule for wake and sleep. The sleep didn't come on automatically. I had to manually change the temperature. I will keep an eye on it.
Before I explain my rating, I must let it be known that I previous home (2 months ago) I had a carrier (Bryant) heat pump installed. The thermostat with that system was incredible. Since we had this home built the standard system is Bryant furnace and air conditioner. The system came with a Honeywell T6 thermostat. This thermostat did not arrive with an operator's manual, one had to go online to find the manual and it did not detail the operation!!! It gave very little information. The on screen menu was not intuitively obvious and was challenging to navigate and could not give the information and control that I expected/wanted. There is no equipment status and setting schedules (without explanation) sucks! I was an electrical/software engineer and I not seen this interface and documentation so poorly presented.
