I have one of those horrible little Flomasta remote thermos controller boxes with the tiny spongey buttons. It's very complex to program so I only have it set on manual on/off. I have just ran the heating for a few mins and turned the box off which shows nothing on the led display. The heating continued to run which has never happened before. The only way to stop it was to turn the box on and off again.
Can anyone please tell me why it would fail to turn off the boiler when off ?
