I can't answer for the wiring colours (they can wildy vary on installer), but the way it wires
N=N Obvious
L=L Obvious
HW off= terminal 1
HW on= terminal 3
CH on= terminal 4.


If you follow the wires to the wiring centre.
HW on connects to clyinder stat common
HW off connects (in some way) to the grey wire on the diverter valve)
Ch on connects (in some way) to the white wire of the diverter valve.
When I say some way, if you follow the cables, it should become apparent, if it dosen't consult someone who does know.

Terminal 2 is CH off which is NOT used on any CH system I know of.
