Hi all,
I just pruchased 2 nest 3rd gen thermostats frm screwfix on a deal. The system i want to wire these up to is a valved system. I have a thermostat upstairs and downstairs.
They are Myson thermostats are battery powered , using what looks like a relay and a comm wire to switch the myson valves.
The myson valves are then wired into a box on the wall that also seems to be wired into the bioler and the comm wirs from the thermostats.
Obviously this set up is a little more complex than other i can find online. I am pretty good with basic home wiring, but i'm not sure where to start on this one. Pictures of the set up attached.
