Fine people of the plumbing world.
I have accidentally pulled out some of the wiring in the strip terminal that connects the 3 port valve, pump, controller, boiler & `stat. (a shelf collapsed pulling wiring out......eeek)
The Honeywell 3 port valve (40003916-001) has 6 wires attached, all info online I can find have 5 wires. I have identified and can connect the wiring for each other component, but my system does not have a room thermostat.
My problem is....How to wire the 6 tails from the 3 port valve. One colour I cant identify, `cos i`m colourblind and where to connect the white wire that would normally connect to the room `stat.
I hope this is clear and many thanks in advance.
Steve Anderson.
