Wiring Honeywell EvoHome Reciever to Worcester Combi Boiler

Post by 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?

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.
