Wiring Honeywell EvoHome Reciever to Worcester Combi Boiler

[HansFeltasnatch]

Hi All

Hoping that someone can help!!

I have recently purchased the new Honeywell Evohome wireless control system, however i need to wire the wireless relay reciever to my worcester CDi combi boiler.

The honeywell reciever is model ref BDR91. The wiring instructions say that i need to wire to terminatel T1 and T2 on boiler, however the worcester boiler has only L, N, Ns, Ls, and Lr. I take it that the reciever is wired to these terminals in some way?

Any help would be really apprechiated.

Thanks in advance

Mike

T1 = Ls
T2 = Lr

Reciever first.

A to Ls
B to Lr

L to L
N to N

Thanks for the reply, just to clarify is this all i need to connect to, or do i still need a 240v supply?

Is the attached wiring diagram right??

Take the switched fused supply to the boiler first, otherwise ok

Nope, you need to take the neutral to the boiler as well

yep that'll do.

There will be a link between Ls & Lr that should be removed.

Just finally getting around to set up my evohome ready for the winter and do this wiring....!

Just one final question, i currently have the wireless digistat, do i still leave this connected within the boiler??

No it will conflict
