We recently built a house and installed the warmly yours heating system. To make a long story short a couple of tiles had to be replaced and now when I turn on the thermostat, the test light comes on and the floor doesn’t heat. Would this be caused by the tile guy cutting something? Something else? Thoughts?
Thanks for any help.

Welcome to the forum!

Pulled up tile sets the warning lights flashing for me. When tiles are being removed it is fairly easy to damage one of the heating wires, if one of the wires were to get a good scrape in it, the GFCI in the thermostat would trip every time the system was turned on. I would recommend we take resistance (Ohm) readings on your floor mat in order to determine what the issue is. If you are comfortable taking the readings yourself please call at your convenience and our technical support department will walk you through the necessary steps, if you don’t feel comfortable working with electricity you may want to contact an electrician.

I hope this information helps! Please let me know if there is anything else I can do for you.
