I have a potterton 80e bolier and programmer single pump with HW and CH valves.
Problem boiler continues to heat radiators once programme ends. temperture can only be controlled at boiler Thermostat only way to close down boiler and close CH valve is to remove power at mains.
If room stat is selected to zero and programme starts boiler dose not run Select room stat to call for heat boiler runs. return stat to zero boiler continues to run.
I have noted with programmer off and room stat selected up for heat then the selection of advance on the programmer the boiler runs if advance selected again seconds afterwards boiler stops. If left to run control is lost again.
Don't have circuit diagram to understand whats not removing the live on the valve which I assume is being held upon so calling for heat!
Any trouble shooting types very welcome I dont think it the programmer you can remove the panel and still the boiler runs on.
HW performs correctly at all times
