Thermostat - GFI Error

I have heated floor with an Aube TH115 thermostat.

Lately I get the GFI error several times a day (red light on the top of thermostat which cuts the power of the floor heating system)

I read somewhere that I had to return the thermostat to the supplier. Somebody else told me it I had a short circuit somewhere.

Can someone help me troubleshoot the issue? Can I run some diagnostic tests myself? Or am I due to call a specialist to identify the issue and fix it?

Is there any chance that someone's pushing the "test" button? Is there a practical joker in your family who likes to mess with you? If not, you probably have a wiring fault. Either a hot-to-ground or a neutral-to-ground fault on the load side of the gfci will trip it. Be absolutely sure the power to the thermostat is off, then remove the load-side wires and measure the resistance to ground from the black wire and from the white wire. Your meter should show an open circuit. If there's a fault somewhere, look for damaged wiring between the thermostat and where the wire goes under the floor. If you don't find anything, you're probably better off to call in a floor heat company with the specialized equipment to locate and repair the problem.
