I wire up S plans quite often and I have never needed 6 cores plus CPC.

Depends on how through you are being on the programmer to wiring center
connection. I can see 9 wires being used:

Supply (L N E)
CH (NO C NC)
HW (NO C NC)

One wouldn't normally need the two NO's in S Plan and the two C's could
share the L but you loose flexabilty at a later date by not having
everything back in the wiring center.
