Hi Just wondering if anyone has come across similar problem with this thermostat. Had it fitted one year ago and has been working perfectly until this weekend.
The thermostat has been programmed to come on and off at set times but now the boiler is coming on when the themostat is showing that it is off (ie no flame showing) and not at a time when it is programmed to.
Last night it was on all night and house was like an oven at 4am this morning when I was out in shed where boiler is with a torch! Today have put in new batteries and tried resetting all the timings but the boiler is still coming on when it is supposed to be off.
Heeeeeelp
Any advice gratefully received.
