Mine does that too sometimes. It's a lot less after a service when the gasman hoovers all the crap out of the burners. I was going to use a microcontroller to automatically reset it but the wife wont let me fiddle with gas appliances; she CLAIMS (somewhat dramatically I feel) that I might blow...
I work shifts, including night shifts, at home and often forget to change the programmer to match work times/bed times. Thermostatic valves are no good if you've forgotten to turn the heating on.
Unfortunately it can't heat the house to 20c, but heat the bit where mrs H sits to about 55C to make her happy (all through the summer she was sitting with a blanket over her complaining about the cold)
He wasn't talking cobblers, the room stat does nothing; turn the heating on and the boiler fires up no matter where the stat (it's still there) is set.
A stark lesson in not letting a retired family friend's brother do a job (even if he was fully qualified).
I'm thinking of shelling out on one of those Hive thingies to control my heating and water.
Thing is, the old feller who installed a new boiler a few years back "bypassed" the room stat (said we didn't need one with thermostatical valves).
Anyone know if I can just add a hive and "unbypass"...
