Works, but very poor in reporting real-time energy usage. It take 78 hours (if you've lucky) to see your "run time". This should be all-but instantaneous.
The thermostat is easy to set up and easy to manage. However, in spite of the system being known as schedule on random mornings, the heat will come on 30 minutes before it’s scheduled to come on. I have redone the schedule several times thinking I had made a mistake but nothing seems to correct this weird fluke.
This little unit is great. The techs set it up when they finished installing my new HVAC and showed me a few things with the new thermostat. Its simple to operate and easy to use.
