Dan, when one is married, one learns to accept one is wrong when one is right. That is how the cookie crumbles. In this case I was right/ perhaps wrong, but accept I was wrong, know what I mean?
Must edit my posts in future bofore posting is what I have learnt from above

When one is married - one should also take what one can get.... And have a ready supply of excuses/reasons for ones thinking....
And of course.... the more right you are the more fecked you are when that cookie starts crumbling.

No.
You need to understand how the boiler logic works.
My plan is as follows:
Currently, HW, UFH and RAD zones are wired as splan +.
Im looking to use the drawings mentioned earlier for splan to connect as follows:
Live in to programmer for HW. On from programmer to Cylinder stat. On from Cylinder Stat to live on HW zone valve, (and the bit im questioning is orange/grey to pins for HW on boiler - 9 and 10).
off from programmer for HW to in for heating programmers (both will wire the same in parallel). on from heating programmers to common on thermostats, and to live on Heating zone valves. Orange/grey to the CH pins on boiler in parallel - 6 and 7)
the off from cylinder stat will feed in to the CH programmer to allow for HW programmer on, but the stat not to want.
So i cant use the orange/grey pairs as voltage free?
There is an external pump for the UFH manifold only, and is controlled by the manifold board.
No other external items that need power once boiler is running.

The aim is to use weather comp, i don't see what the difference is with the relay in place and not. From the original diagram, the grey and orange energise the relay, which connects the two pins... So why not use the grey/orange to connect the pins and ensure that the valve is open when firing up the boiler?
Taking into account that the original drawing is doing exactly that for checking side?

There is a way (several in fact) of doing it without a relay.
