Potterton prima turning it self on and off

Post by Zider_drinker »

Hi

I have a potterton prima which is giving me some grief. It comes on and off when the HW and CH are selected to of and can make some odd noises, hopefully a video has uploaded.

It was working fine and started playing up 2 weeks ago, I originally thought it was the controller so I changed the old switch master sm 400 for a Hive Mini. However I still have the same problem.

My system also seems a little odd, I thought I had a gravity system because I can only have HW or HW&CH. But I seems to have a single pump with a motorised Valve on the CH.

I have uploaded some photos of the pipework and wiring
