In an act of comedy genius, I managed to cut the live feed to our central heating thermostat. As well as a worrying bang, it unsurprisingly knocked out the heating. I reconnected the wires (there were four - three insulated and a strand of bare copper) with a junction box and the heating came back on again. Hurrah! I briefly thought.
Now, the heating comes on but the thermostat never switches it off, which leaves me with a handful of questions:
>Have I somehow knackered the thermostat itself?
>Does it need to be re-calibrated?
>Could I have damaged the electric controls on the boiler?
From what I can see. The thermostat in the hall (the one I killed) controls the temperature, but all the timing etc, is done by the control pad underneath the boiler. The thermostat is an old Honeywell thing which I reckon must be at least 25 years old.
Any advice gratefully received
