Evening all. I've not needed to post on here for a while but it's silly season again and one of my first breakdowns has me scratching my head a bit.

EP2002 blown as was the pump which had started leaking.

Replaced both, pump now runs when heating demand is present but it doesn't warm up.

It's a gravity system with pumped heating and hot water is fine. Looking g briefly when I changed the programmer the wiring didn't need to be changed. Have I missed a seitch/button/setting for pumped heating/gravity hot water or not? I'm assuming it might be an air lock but because it's a crap ups3 I cant bleed the pump to check it's not just air in the pump.

I'm going back tomorrow to have a look but any pointers would be good.
 
So long as you have correct replacement clock there will be a dip switch on the back to make it gravity or fully pumped
Thank you. I thought the same as the old one had that but I didn't see one on the new version. I might have missed it though so will take another look later.
