regarding No 8
Only the WHITE motorised valve and a RED wire (as mentioned earlier) link into this terminal on the block connector.
Not sure if this will help, but the RED wire comes from a 2-core grey cable with the other core being Black and going into terminal 9 in the block connector.

i thought you said n0 3 also joins the white ?
white
also has a red wire in same connector block terminal. This then disapears into the wall. The red wire has a small sticker on it with the number 8 on it.

yes the No 3 (HGT OFF) in my existing programmer goes into the terminal block, connects to white and also has a red wire in it!

can you see where the other end of the grey cable gos ?(red/black)
No, it goes into the wall. I asume it goes to the boiler, or room stat?
ah ha it could go to the room stat as this would then give the signal to close the valve when desired temp has been reached. The room stat is a dial and has a red and black wire feeding into it, also a single core wire. The other end of this single core wire comes into airing cupboard and connects into No 9 on the block connector.

Important!
Amended statement from earlier. About the Black cable (which pairs with this RED core)
'Not sure if this will help, but the RED wire comes from a 2-core grey cable with the other core being Black in a connector block linked to the wire connecting into HTG ON in existing programmer.'

the room stat is useally on the brown wire and the valve will close when you take power of the brown.
and you wouldn't feed a room stat power when the htg's off.
if it connects to 9 that is where the black wire is in n0 9.
Looked again at wiring (lots of them in block!!!) just amended statement about No 9. See above
my heads now going round in circles.
now the black go's somewhere else
now the black go's somewhere else
if i was you i would do a diagram of the wires and no's they join to
and the colours etc from the valve then we can go from there.
as i've changed this diagram so many times i'm getting lost.

sorry.
The wires are difficult to trace in parts and i have had to prize some apart to see where they are linked to. All statements made so far are correct and ammended as mentioned earlier.
