Y plan Switch live and 30 CDI bosch boiler

[clarkerothwell]

Got a 30CDi bosch boiler that needs a y plan wiring up, my spark is away so having to do it my self, only stuck at this point.

I have my permanent supply from fuse spur in to the connecter block on boiler, but which wire do i use as the LS (live supply) and which as the LR (live return) and Which for the Ns (Neutral supply) from the control center???

Is the orange wire the live supply??

I have all the controls wired up, clock, both stats and honeywell valve wired in, (pump internal on 30 cdi system boiler)

ANY HELP PLEASE..

Of course it is, BUT not when boiler is turned OFF on the boiler fascia on/ off switch. With boiler off, SL should also be off.
