Nice thermostat, once it's installed and set up. Had problems with the "C" wire. There was a "C" wire attached to the old thermostat, so figured this one would work no problems. Installed it and nothing. Found the "C" wire was attached to the thermostat but not inside the furnace. Thankfully, I found a YouTube video that helped. Once connected it came up. Took a bit to figure out how to program the "auto change" feature and a few others. Working great now. I like being able to control it remotely. Worth buying if you need the features it has. Never had a problem with a Honeywell thermostat!
