  • Video is too long.

    Use continuity tester across micro-switch, press it, tester gives a reading in ohms, done. Can do it in less time than 9 minutes.

  • @Techozek Thanks for taking the time to comment, yes, that's certainly a way of testing the micro switch.

  • Hi 'monkmsm' thanks for viewing. The grey is connected to a live & when the micro switch 'makes' the orange brings on the boiler, or on some systems; both the boiler & circulation pump.

    The Room thermostat & Cylinder stat control the sw/live to the synchronous motor on respective 2 port valves.
