Contractor installing our new HVAC system did not realize we didn't have the proper wiring for this kind of thermostat and had to come back the next day to re-wire so it would work.
We use the thermostat in our vacation home. Its wonderful to be able to set the thermostat by phone so that our home is nice and cool by the time we arrive.
We had an issue with our main thermostat. One day it just wouldnât connect to WiFi. The error code indicated it needed to be replaced. We chose not to, and a few weeks later we had a power outage. After that, the thermostat has connected just fine.
