Central heating seems to run continuously

[andrewagray]

Hi,

Having some weird problems with my boilermate 2000.

I have never heard the waterfeed top up the store so much before and the store sometimes makes loud banging noises (trapped air?)

The house temperature control thermostat does not seem to work.
It clicks at whatever temperature the house is at but the house is always warm as it seems to be running constantly!

I've read that this is a control board fault?
Is there anything else that I can do to check what is wrong?

Thanks

Turned the full system off and back on and it does not start up properly.

All three green lights come on but when I check downstairs the boiler is not running.

The LED read out does not light up and it just seems dead.

Fitted a refurbed PCB and the system works perfectly now.
