yea that the correct drawing you found , ufh valve is plumbed in on the terminals next to the boiler enable with the link removed ,
I was thinking that was. How to do it but wasn’t sure what would stop the ufh zone coming on if I turned the nest on ( maybe the ufh zone valve won’t fire until...
We got left in the crap by a dodgy builder while building an extension ,
A plumber came and finished the plumbing but he wasn’t sure on ufh controls
We have 2 zone valves installed 1 for radiators and 1 for ufh
At the minute these are controlled from 1 nest stat but I want to split these so...
