I have any my zone valve wiring bares no resemblance to the one on your
page. My zone valve has only 5 wires not six with no orange or grey.

Pls see my post below. the microswitch doesn't do anything. the motor
continuously turns as soon as I ask for water+heat regardless of whether
the
microswitch wires are separated or joined...




The motor will turn as soon as power goes to it and remains powered through
the duration of the call for heat. The micro-switch activates the boiler
and pump controls.

The motor doesn't stop until it reaches the limit set by the cog wheel, so
if the cog wheel breaks any teeth the motor will continue to turn. It is
the cog wheel that moves the valve arm inside the valve and not the motor
itself.

The micro-switch can have as many connections as is needed by the system,
yours only needs two, and can control the pump, the boiler fire up control,
the thermostats, etc. etc. etc.

Now please understand that the motor will turn continuously until the power
is switched off by some other controller.
