I've got a problem that has cropped up over the past few days with my CH.
The thermostat clicks on and off, but the boiler doesn't come on. I can switch the boiler onto constant, it'll start and then heat the house up.
I've swapped the old stat with a new one, but still the same issue, it clicks but no heat.
Any suggestions as to what might be wrong?
