So far it’s great. Pretty easy to install provided you have the right wiring. Has a hot/cold function so no matter the temp the thermostat will turn on heat or A/C. Easy to control remotely through my home WiFi. Large numbers on the screen to see at distance.
Easy to install. There was an extra conductor in the thermostat cable that I used for the required C wire. With the old thermostat, the room with the thermostat was at the proper temperature while other rooms in the house always felt cool. My new T9 thermostat with the remote sensors has corrected that problem. The house now feels comfortable in any room.
Less than a month old and twice now it's dropped wifi connection and won't auto reconnect. This is at a second residence and has not been reliable so far.
This thermostat is not worth the price. The remote sensor is useless, because within hours the thermostat defaults to using the hard-wired sensor. This is the only feature I was interested and it doesn't work. Also, utility override "savings events" appear to be enabled by default, even if you never opt in.
