Devireg Underfloor Heating

[fudge2604]

Hi,

Have just turned on my electric underfloor heating controlled by a Devireg 550 stat, it heated up for a day since then nothing. The thermostat is on and the display is working and showing no error codes. I have checked all the wiring and everything is connected OK and I haven't screwed or nailed anything to the floor since last year which may have damaged the mat.

All I can think is that the Devireg is faulty and needs replacing but thought I would post here to see if anyone has had similar before I spend nearly £100 on a replacement stat,

Thanks

Do you have a multimeter??

The first step is to check the resistance of the probe and the element to see if they are still working!

There is a fault finding guide in the user instructions that tells you the steps to go through.

Don't know make, it came from TopsTiles. This year switched on to test, thought it was not working, then realised it was, not sure what was going on, there is a tell tail light to show calling for heat which was on. I am guessing it has been driving out moisture? it is in a wet room so tiles often wet. It has never been much good, some day I will use a clamp-on meter and measure. But it has always been a bit of a white elephant so would not spend to fix it.
