My SmartStat of less than three months old continues to trip as if a ground is indicated. However, I have an infinity ohm readings between both core ends and both shields. The SmartStat started this problem about two weeks ago and would not reset unless I cycled power to the system. Now the SmartStat display is jumbled and trips as if a GFCI where no fault exists. Where do I go from here?

There are a few things I’d like to take a look at before we determine that the thermostat is defective. Is the system on a dedicated circuit? What size breaker is it on? Is the breaker non-GFCI protected?

I would recommend calling our tech support team at 800.875.5285, and they should be able to walk you through everything. If the thermostat is determined to be faulty, we will gladly send you a replacement.

What if you hear rapid and intermittent clicks coming from the SmartStat (for about 10 seconds)? It stopped and I noticed the floor wasn’t heating anymore, so I tried turning it off and turning it back on again. The clicks came back and the red light came on in the left panel of the Thermostat cover. It also didn’t trip the GFCI circuit breaker. I’ve left it off ever since and sent a note to you guys, but havn’t heard back. Thanks! Your thoughts?

Sal,

The first thing I would recommend is replacing the GFCI breaker with a non-GFCI protected breaker. Occasionally when there are 2 GFCIs in series they will nuisance trip each other.

When you hear the thermostat click, what you are actually hearing is the relays switching inside the unit. If the thermostat keeps clicking, the relay may be going bad. Please call our tech support team, and we will walk you through all the necessary testing to come to a resolution for you.
