Reliability of fault codes potterton

[John.g]

Possible all right I suppose but strange that the fault only showed up when both systems on, did you note the flow gauge readings on the UFH manifold?
Is the cap on the automatic air vent on the (right side) of the flow manifold open, if not open it, release any air, close it again and test regularly for air.

I haven't done that yet John. I've also not tried Shauns suggestion. It's been a busy weekend as I was hoping the plasterer was coming today so I've been flat out getting all the electrics finished ready for him. Cutting out for the sockets / downlights etc, a couple of tip runs and just generally sorting through everything.

I'm not sure the plasterer is coming now though as he's not been in touch. If he doesn't show then I'll stick the heating and UFH on and try and see what's happening.

One of the jobs I did get done was battening and fixing plywood to that wall that the manifold is on (in the photos) so I disconnected the wiring centre and then fixed it a bit more neatly to the wall (fitted a local Switched Fused Spur etc). Got plenty of photos of how it's connected so planning on trying to find the manual and get my head around all that to make sure it's connected up correctly etc.

The plumber did say that I needed to "let him finish it" (basically, stop worrying about it until it's all done) so I'm assuming that he's aware that it needs balancing and that there's still stuff to do on it.
