Need some advice. I have an ideal boiler he15 icos and the heating and hot water is off but the boiler it displays C and it keeps firing up like it’s on continually. What does that mean. Whatever I switched on last ie if I put the heating on for an hour, the heating is still on after an hour and boiler keeps firing up even though it’s off. Not sure if it’s to do with anything, but recently changed the pcb 🤷‍♀️.

I read on another forum that it could be a zone valve, but the gas guys on here may know what the problem is..

It would probably be better if you posted in the right section as your question is technical and appears to be related to a gas boiler.  The energy forum is where gas experts hang out.  This one is oil, LPG and alternative fuels.
