Hi, just recently wired in my single zone (4 loops) wet UFH system. I found it relatively simple as I think it is a basic layout. Heating is S plan (UFH/Rads) however it is only wired together using (the supplied) box with a big choc block connector rather than these fancy wiring centres you see. General flow is stat powers up the 2 port valve, which then send a signal to both the boiler and pump et voila. However the pack included an actuator valve which sits where the flow enters the manifold and AFAIK acts as a kind of TRV, but i can't seem to figure out how to wire it. It has 4 wires, so I can only assume Live, Neutral and the other two maybe a switch similar to how the 2 port valve works, but trial and error hasn't really worked.
Anyone any ideas please? Wiring diagrams seem to be impossible to find for the 4 wired versions
