You said on 19/09 :-

A synchron motor, as with any standard motor, will continue to turn when
energised until told to stop by some kind of switching system. The small
micro-switch in the motorised valve is such a system

According to what BW has said. the motor isn't told to stop by the
microswitch, it stays energised as long as the 'W+H' switch is toggled. The
microswitch doesn't stop the motor, it activates the pump & gas ctrl valve.

Pls check my wiring sketch link from the older posts and if you see ethings
differently then pls advise..
Thx

I was lead to believe on Ed Sirett's post that the microswitch stopped
the
motor ( i.e. tripped something that stopped supplying power to the
motor ).

Which post was that, or do you mean something in the main FAQ?
