Worcester Greenstar 40cd1 / Y Plan

[rainstorm]

Evening all.

Getting a little confused with regards the wiring for a Y plan when there is no controller to wire to (an internal programmer is being fitted).

Since the main feed is wired into the boiler, then a switched live, switched neutral and boiler demand is taken to the wiring centre (no HW on or CH on), where do the orange, white and grey from the 3 port terminate to?

Any help would be appreciated!

they dont a 40 cdi is a combi boiler and a y plan system is for a heat only boiler......
contact me via pm if you need more help.

Thanks prest,

Looks like I've got the model no. wrong as it is definately a floor standing system boiler. Been on to tech help and they say you cannot have internal programmer so I think the heating engineer might have made a mistake.
I'll find out later.

All sorted.

Model was a Greenstar fs 42 cdi.

External programmer was needed, job's a goodun.
