hi i have a combi boiler with drayton wireless thermostat, the stat ans receiver don't seem to be communicating ive run through the re connect sequence with no success, and i cannot start the boiler with the override button, ive read that it may be the scr at fault and that it can be bypassed by moving one wire, can anyone tell me which wire is it?

Move connection 3 on the scr and link it with the wire in connection 1, this does away with the thermostat completely.

Make sure the electric is off before attempting.
