The fan function needs to be separate from the AC setting. Everything else works perfectly. But when I change the temperature on the AC or heat the fan changes from continuous to auto.
I had the T9 w/ 1 sensor installed for 3 days. The AC would run for 6-10 minutes, turn off for 7-12 minutes and cycle like that over & over. I tried moving the sensor to different places and setting only the thermostat and/or/only sensor as the priority temp reading. The thermostat software algorithm that is supposed to learn needs a lot more work. This run rate will wear out the HVAC equipment a lot faster than my high end non wifi thermostat I just re-installed. My 5 year old high end thermostat that has compressor lock out and differential - cool swing - heat swing settings, runs the AC for 12 - 14 minutes and stays off for about 40 minutes. The house stays very comfortable and my equipment is not turning on/off 5 times more an hour.
No, I would not recommend this to a friend.

Easy to use, but what I really hate about it and wish I never got it, is that its a fricken NIGHT LIGHT. It shines bright towards my bedroom and there is no adjustment or any way to turn that darn back light off. If your thermostat is installed in a room that needs a BRIGHT NIGHT LIGHT, then perfect. But if your thermost faces rooms that you sleep in, the I suggest a NEST THERMOSTAT.
