Hi, I have a Glow Worm boiler in my loft, and a Drayton LP722 7 Day Electronic Programmer (it says here!) controlling when the heating and hot water come on. The thermostat control is in the airing cupboard on our landing, with the thermostat itself on the landing.
Over the past few weeks we've had a number of incidents where the thermostat has gone off (tripped, I assume). The boiler is still on, and when I switch the boiler off and then on again the thermostat starts up again.
As I say, I *think* it is tripping out, but am unsure why. And it does it without warning too!
Any suggestions please?
Thanks in advance
