Good Morning, I replaced all my old unipor mechanical thermostats with the Honeywell DT90E's a few months ago. All was going well until the one in the room that uses the most heat started constantly clicking on off like a clock. I read on here that if a reset doesn't fix it then the thermostat...

I've bought a new build that followed the 2010 regulations. In the domestic heating compliance guide 2010 it states that a timer and thermostat is needed for all electric heating panels. However, I believe this is just a "guide" so was trying to find out the official requirements. The house as...
