Hey chaps, I am in need of some help. I have the above motorised valves on a system and cannot figure out or find out any where what the wires are. It has yellow, white, orange and blue and green and yellow. No grey on it. So which will need to be wired into the live in the wiring centre? Also, these valves have no manual lever on them. All wired into a Randall wiring centre.

Cheers for the help in advance guys

Sunvic valves, including MoMo types, normally use exactly the same wire colours as other makes. Could the cable have been changed?

I assume they are zone valves, not mid-position. If so, it should be possible to work out which pair are for the motor (blue and ??), which leaves the other pair for the auxiliary switch. A multimeter would help.
 
They are definitely the correct colour wires. They're in my honeywell book. But, it says to isolate the white wires and nothing about a permanent live. So am stumped
 
I hate them personaly and tend to swap them back to honeywells if possible, wiring isnt an issue normally though.
 
If there MoMo valves, you need live to open, live to shut? I.e link yellow to cyl stat calling and white to cyl stat satisfied? That's what I understood from wiring diagrams above?
 
they are absolute garbage Mutley, there should be a Perm Live grey

2 port - 4 wires blue. grey.brown.orange
3 port - 4 wires, grey orange, white .blue
 
Wow that diagram boggles me. I am only just getting to grips with normal 2 port and 3 port wiring. What the heck is that relay all about. 3 wires from cylinder stat, 3 4 from room stat and how many from programmer. Think it would be easier to just lose money and buy a couple of new valves and room stat:(
 
mutley races i do i am off this week so am just gutting the house the garage and clearing all the stuff out
 
When you say link white and yellow with cylinder stat, do you mean as in using a honeywell wiring centre?
 
If I would have had a bit of time I would have tried to figure it out, but it was easier and quicker I believe to just stick with what I know. I did bring the old wiring centre home with me to have a look though:stuart:
