If it is a Mid Position valve, which with three pipes, it will be, then it isn't as simple as two for the motor and two for the aux switch. Each make will be different, but typically:
One core Earth,
One core Neutral.
One core Boiler/Pump FIRE(live leaving the valve).
One core HW SATISFIED(live entering the valve).
One core CH DEMAND(live entering the valve).
The valve will always allow water to flow to the cylinder unless the HW SATISFIED recieves a live from the time clock HW OFF terminal, or the CYL STATS SATISFIED terminal.

scuse me when has a c plan had a mid pos valve
Memster said:
He did mention a valve, and by the number of core+pipes, it seems to be a mid-position.
It was Memster who stated it was a C plan, he could be mistaken
fair comment mate but till he tells us what he has actually got we are all p*****g in the proverbial

bit of a challenge that was, getting 1 channel controls to work on digital 2 channel
but just to throw a spanner in

I am reckoning the Y plan. You certainly have a mid position in my eyes. What is the model number of the valve??
A V4073A1039 is the part number for a Mid Position Valve with 22mm Compression Fittings. This is for a Y Plan system.
Use the diagram on the link given for the Y Plan. Sounds like you need to supply a feed of your own via an FCU, and determine what the 3 core does at the boiler end.

whats the best way of seeing what the 3core does? because it is definatly live and the only way to get at the boiler is to rip the fireplace out and ive got enough work to do with out starting on another room
and the thing i dont get is all the wirese were there and working now i got to run a new FCU.. might be easier to do this? would i run that off the 30A fuse ring mains or off the same cuircuit as the 15A thats for the immersion heater?

If nothing has changed, maybe there is an FCU near the fireplace back boiler. Look for it. If there is, the 3 core may be Red Live feed, Blue Neutral Feed, and Yellow Boiler FIRE.
You can meter to see if the red is the live?? And join the red to the yellow and see if the boiler fires??
