Diverter Valve Wiring
 

Can anyone help with the wiring instructions for a 3 port Diverter
Valve ? The valve (not a mid-position) was supplied from a Italian
company and the intructions do not match the wire colours.

There are 5 wires.

Yellow/Green
Blue
Red
Grey
White

I assume that some of the wires become live when the valve is in
different positions.

Thanks

Richard

If the wire colours don't match the documentation,
then you need to figure it out from first principles.

Can you open the lid of the motor assembly, and just look at what they
connect to?

If not, then you will need an ohm-meter.

Check yellow / green 0-Ohm to the body. This will be the earth.
Equivilant to Yellow / Green on a standard honeywell valve

Then look for a couple of K ohms between 2 wires. ( perhaps the Blue and
Red ).
That will be the motor.
Equivilant to Blue / Brown on a honeywell.

The remaining pair will be the microswitch.
They should be open-circuit to all the other wires.

They should be open-circuit to each other with the valve de-energised.
To fully test the microswitch, you'd then need to apply 240 to the motor,
and observe the microswitch pair on the ohm-meter.
They will go short ( 0-Ohm ) when the valve is fully opened.
Equivilant to Orange / Grey on a honeywell.

This is a _three_ port valve. It's close to the colours use by Honeywell
if red were orange. The OP should read the main FAQ and see if the unit
looks like it is wired up Honeywell style with red for orange.
