I ordered and installed this thermostat because our 2nd level (furnace in the attic above the second level) was staying 10-15 degrees warmer than the main level (thermostat is on the main level). I added two room sensors upstairs and so far so good! The app makes it very convenient to control settings and temperatures as well.
The thermostat will not work right keeps freezing up woke up one night 88 dagree in house it was set to 72 could not get it to shut unit off went out side pulled main braker went without heat the rest on the night and bought a different thermostat the next day
I was worried that I would get stuck half way through the setup and have to hire an electrician. I was wrong. Setup was very easy. Shutting off the power and opening the maintenance panel on your furnace can sound intimidating but it's really not. Turn off the main breaker, install the C-Wire Adapter and you're good to go! Also easily connected to the Amazon Ring app.
This is such an easy thermostat to use. Such a comfort to watch the levels in the house and change so easily. This one is in our winter condo, but will definitely consider getting one for our house back in MN. Thank you to IID of CA and Synergy.
