    Master valve is my terminology as it governs the subordinate vavles, look at the diagram, it's in series with the manifold valves. The manifold valve triggers the boiler when any of the thermostats call for heat. All the thermostats are wired into a relay for this purpose.

    Could be an old valve or it could be for a heating circuit. You need to double check it is for the UFH only.

    I’ll double check again to be sure there is no third circuit, but otherwise I’ll unwire and leave manually open, then tell plumber to remove when he next drains.
    Thanks guys,

    You need to make sure that it is definitely open all the time and cannot close at all or it needs removing at the same time.
