Customer Questions & Answers

I Have this thermostat and it is now a white screen with no details. It also is not heating my floors.

Asked by: Karlas
A white screen in very unusual. Try to turn off the breaker in your circuit box and then back on. See if there is an error code on the screen. If still nothing then the thermostat may be faulty. Did the thermostat ever work? Is this a new installation? If it falls within the 3-year warranty please return under warranty.

I currently have a double gang box that contains my current / failed thermostat. I am planning on using the same box as to not have to drywall, mud, and paint. Is there a standard face / cover plate that fits this unit when installed into a double gang box?
Asked by: Jerry
Jerry, Unfortunately there is not. It's a great thermostat but there isn't a standard cover plate that fits a double gang box.

Asked by: wilman
I bought the exact same unit about 2 weeks ago and have the same problem. My floor is not heating but everything is wired correctly and the display reflects what would appear to be correct information. That said, despite the ))) symbol turning on (heating) there is no heat. Could this be a part of a defective batch?

I have one of these, showing an error code of E0 which means replace. Sticker on back says UCG-4991.
