    Have zone 1 downstairs, zone 2 upstairs, zone 3 water. Zone 1 + 3 work fine. When I turn on so e 2 the boiler doesn't start and the little box in hot press doesn't have it's light on. I've turned the upstairs thermostat dial to zero and back up the 26 (the little click on/off happens around 22) but still no red light in hot press and boiler won't start. If the boiler is running and I turn on zone 2 still no red light in hot press. Do I need electrician or plumber? Thanks

    It could be the room stat, but more likely to be the 'little box' (motorised valve) has failed, as it's common enough.

    Best get a good plumber that understands heating controls.
