The timed economy7 controller supplying our immersion heater has stopped working. There's still power to the controller, the immersion still works on boost, but the dial of the timer doesn't go round so the immersion doesn't switch on at night.
It's a fairly old unit so may just be best to replace it. But before I do, any other ideas about what might be the problem ? Could it just be that the rechargeable battery has gone, or does that only kick in during power cuts ?
All help much appreciated.
