Hi Joe

I presume you have the wiring diagram for the boiler?? if not most of the details can be taken off their web site, inc some wiring of accessories:
Greenstar 30CDi literature - Worcester, Bosch Group UK installer site

Hope that's of some help

Hi Duncan,

I've read the instructions, twice, and still cant get the boiler to turn the C/H on. On the receiver I have 2 terminals, Live from Load & Switched Live Output. WHere do these go in relation to the boiler??

Cheers

I'm no expert on these bloody things but have wired a greenstar cdi 30 combi with a rf stat a couple of weeks ago. The receiver end needed its owne power from a fused spur, then the flex wired into the boiler, seem to remember I had to take the link out off the receiver before it was interested in anything, Sorry if this isn't quite the answer you need

Worst case I'm back up at the same place on Thursday, to sort out the original Sparks random wiring, So could have a look what I did then if you like.

Cheers

Thanks Firebucket but I think I was just being a bit slow, long day!! I didnt have all of my 5-cores wired in. L+N need to be put in the L+N terminals on the receiver, remove the link to make volt-free, then Black to Common(Load), and finally Grey to Switched Live. Make the L,N,E connections followed by the black and grey (remove link again!!) and TADAR!!!!!
