As a keen diyer I like to have a go at things myself, but on this one I couldnt have done it without your know how - I had almost given up the other day but glad I didnt as I had asked the company that originallt installed the UFH and no one got back to me. Very grateful Cheers

Thanks again, will let you know how I get on.

I think I got .... Thanks very much, I have 2 questions: Q1 - Am I right that once I reconnect the new flex blue into 5, 5 will effectively only have the grey from the thermostat, the brown from the UFH valve and the new blue flex (connected to the UFH control box unused terminal on r/h side), then connect the new brown flex to terminal 11 and the other end to the UFH control box unused terminal on l/h side Q2 - What do I do with the black wire currently in terminal 5?

Black in 5 goes into one of the thermostat grey 4core which enter the wiring center at bottom right

Hi Brown into 5 and Blue into Neutral block. What I cant undertsnad is that with this wiring as it is in the wiring centre the UFH works fine for one zone1 its only the other Zone on the other room stat that doesnt open the valve.

Good morning ProDAve, I had a look in the wiring centre and I can see: - UFH valve = Orange goes into 12 and Grey into 7 - Radiator Valve = Orange goes into 6 and Grey into 7 - HotWater Valve = Orange into 6 and Grey into 7 Does that help? hope I'm not being a nuisance 😞

Will have a look and confirm. Thanks for your help

Hi yes, there are three motorised valves, one for hot water, one for UFH and one for radiators. The UFH valve only opens when Zone 1 is requesting heat, the second zone doesnt open the valve when requesting heat.

Will this then also open the UFH motorised valve?

Sorry for the basic questions and thanks very much for your help. I will have a go and will confirm if it has worked.👍

Thanks very much for this information. I can also confirm that the wires 2 and 3 (brown and black) which i traced are in fact for the radiator thermostat (I totally formgot to mention this 3rd stat). I was able to confirm this by doing a continuity test with the thermostat when requesting heat. Does this alter your recomendation?
