Potterton Prima 60F not firing up....help please needed

dazzystar · 26 Apr 2015

I've put the old programmer back and the room stat now has power. Don't think the new one was wired correctly by my pal.

Now I have the pump running when selected HW and no pump running when I select CH !

I cannot help thinking that if you had called a professional at the beginning then you might have had everything working perhaps just for the £84 diagnostic fee!

Or if any part were needed still not much more!

That's probably true Tony but we are where we are with this I'm afraid.

All indications would point to a faulty zone valve or microswitch. Would you agree?
