British Gas F2 Manual Transmission
Does anyone know why my rc plus wireless system doesnt want to turn my CH on? Worcester combi boiler seems to be working fine as HW is all good.

Thermostat seems to be reading/displaying as normal (flame for CH appears) but it doesnt seem to be communicating with the boiler as no heating at all.Someones suggested resetting and reconnecting but i have no idea how to do this. Managed to download one of the manuals on the top of this thread but no joy with the other.Any suggestions please? Desperate - my kids have a cold already!CheersElaine.

Switched both back on again.
I manually raise/lower the temperature and as I do I can see the red 'communicating' light flash and the green 'on' light will come on or off with the flame symbol on the controls. The boiler will not start.I checked all the connecting cables and the boiler stat codes, and as far as I can figure out it is probably the relay in the receiver box on the wall next to the boiler that has failed (these controllers switch a 240v signal to the boiler for on/off).
My controller box also runs a pump to occasionally pump condensed water away into the drain, and I guess the extra load of that pump shortened the life of the relay.I guess the best option will be to replace the thermostat system as it sounds like your boiler is working just fine.Best of luck to you.
