    My boiler fitter has fit the boiler and said he is away for a few weks when he will fit the thermostat.

    i reckon I can do a lot my self. My sparky friend can help me on the power part.

    ok I have 2 zone valves and a typical system boiler type system

    from the manual I have used the but which says "mono zone- 2 2 port valve". I assume this is the correct one?

    so from the manual it says 3 wires from zone valve go into ch1 and dhw. But the zone valve has 5 wires too it.

    can anyone help IMG_7941.jpg IMG_8554.jpg IMG_8545.jpg
