How can I fix my Potterton Profile 50e control system ?
When Potterton Profile 50e controller is set to 'off' , the boiler still runs .Is the wiring circuit damaged ? Building work is taking place adjacent to the boiler.
Can you show a wiring diagram which includes a froststat.
the frost stat has a perm live that overides the prog/controler so if that is exposed or has been ajusted during builging work it could cause the boiler to kick in
