Hi, our boiler won't fire up for the radiators but it still works fine on the hot water. It's a Worcester boiler with a Siemens wireless control unit. was working fine up to now.
What you need to establish is whether the stat is communicating with receiver and/or the receiver is
working.On the receiver is an override button press it and see. Are the batteries ok? when you operate the stat a red light should blink on receiver
