These are OK. Came with my new house. Easy enough to program but I was disappointed to find out that I can't set and forget. I have to choose either Heat, Cool, or Off. I want a thermostat that will decide for me which system to call.
Pretty good thermostat that works well. The only issue i have is that the screen blanks out. My previous Residio stayed illuminated for easy viewing from a distance.
It is easy to use had an AC Electrician put mine in because I had a lot of extra wires was not sure what I needed. easy for the ap also! My old one was ancient 30 years old. I found this one has had no issue keeping the AC doing great!
