Thermostat is easy and nice to use! For some reason when we program it, the A/C unit kicks on earlier than planned. (i.e. If you set the Air to come on at 5:00pm, the Air may actually start to kick on 30-60min prior. Our thinking is the program will turn the Air on to the temperature you like and have it at the temperature by 5:00pm) Be mindful and set it accordingly.
The value and convenience this thermostat is well worth the purchase. Plus it was easy to self install. The only downside is that the screen does not dim at night.
We have 2 of these thermostats now (one for our second place) and it makes it so convenient when we want to get away to the mountains. It's so easy to maintain proper temperatures in both homes.
I have had other WiFi thermostats, but this model 9000 is a big upgrade. The features I like the most are the weather forecast that you can access... the backlit display and the ability to change the colors.
