Central Heating Programmer
prelude1980 - 1/1/12 at 12:32 PM

Hi all,

Hope your having a good New Years Day.

I have a Potterton EP6000 central heating programmer that has decided to stop working I think?

Basically if I turn the hot water on it works fine and starts up the boiler. But if I turn the central heating on then nothing!

I removed the panel from the wall and took the backup battery out and left it a bit then put it back on the wall, initially it worked again but second time of trying it nothing.

So I think it's the programmer gone rather than anything else!

Am I missing something obvious

Thanks

have you checked the boiler and any manual over-ride that there might be?

I can't find any manual overide but the hot water side works so I don't think its the boiler

If you're confident to do this then you could take the wires off the connector on the controller and short out the ones for the CH. Obviously do this with the electricity off. Then switch on the electricty and you should get CH. If you don't the problem is not the controller. If it works it's the controller, probably just the relays. You can get a replacement called the EP6002 which fits the same backplate but it slightly less antique.

May sound obvious, but is your thermostat working correctly?

could be a faulty/stuck zone valve!

Does sound like the motor valve to me this will be alongside the emmersion tank and switches the supply around

Been having simmilar problems with mine,lights & timer come on but does not send the signal to the valve,if I give mine a 'tap' it kicks into life again and moves the valve,new controller/programmer on order for me.

I just tried shorting the CH and it did start working so i just ordered the EP6002 as it makes changing everything very easy!!

Slightly less antique did make me chuckle!! i think the controller i have must be 20 years old


Thanks for the help
