Hi, I've inherited an old oil boiler, must be 20 years + old, Falcon Series 2, (Stelrad Group), that's just developed problem with the boiler thermostat. ( at least I think its this ). The central heating was previously causing problems with some rads being cooler than others, but thanks to great advice from this forum thats now cleared. This problem arose after I tried to clear up the wiring around the boiler ( I know, leave well alone you might say!") but the pump was running all the time, wires all over the place etc. Anyway, following my fantastic rewire the boiler themostat didn't work, temp of the boiler ouput shot up to 100C. I restored the wiring back to previous state, but now the boiler temp only reached 65/70C, although it does switch of now. (the room stat still calls for heat). The boiler stat is set to max as well.
I can't find any details of this boiler anywhere, maybe the themostat is malfunctioning, any ideas on what to do, or where I can get details of this boiler ?.
I'm also concerned that the original wiring is correct.
There are 3 wires attached to the boiler. One power in from the timer, one from room stat, and one other with power, not sure ifs it power in/ out. Pump on all time.
