Good video, learnt some new things regarding testing, the only thing i can mention is u didnt say where the switch live on the grey wire comes from.
Room stat, cylinder stat etc.
Good video, would like to see others.

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.
