[carrpaul]

hi there dose any one know the wires colours for changing switchmaster 2 port to honeywell v4043h
switchmaster colours i am not sure on are yellow red white

5 wires?
If so the red and orange go to orange in the new valve, white goes to grey, yellow to white, blue to blue and the earth isn't used.

Pretty sure it's the following but best to test with multiumeter first

Switchmaster to Honeywell
earth to earth
Neutral to neutral
White to brown
Yellow not needed as honeywell has spring return
red to orange
Grey on honeywell - connect to permanent live in wiring ctr

thanks for help i ended up with;
switchmaster honeywell
earth - earth
blue - blue
white - make safe
yellow - orange & brown
dident go in to wire center just cut valve cable & made my own junction box as wire center bit tight to trace .

this is the wiring for a switchmaster 3 port valve (red is sl from cyl stat so gets linked to orange).
