Plumber doesn't really do wiring, which has left me without a working UFH system. No electrician available for the next week+ so plumber is now looking at doing it himself. I want to make sure I have an idea of what goes to where/some ideas to discuss with him to make sure he knows what he is doing.
The below image is what I have, and the Live/Neutral I am happy with, but it is the switching side I am struggling with. In short, I am adding a second pump & third zone valve to the system, but would like the UFH, Hot water and Rads to all work independently of each other when required.
I have A1 and A2 from my Heatmeiser thermostat, then a third wire for the pump and 2 wires from the Zone valve. I am handy with electrics, but it is the complexity/logic I am struggling to get my head around with the system. Originally was going to do it myself, but with the plumber on board now I'd just like to know for my own reference,
Is anyone able to advise in fairly laymans terms? Many Thanks
