Wireless room stat help pls

[msc125]

Hi,

I have a Worcester Bosch Greenstar 24i Junior, and need to fit a Honeywell DT92E Wireless room thermostat.

I have the following connections on my boiler:

LR, Ls, Ns, N, and L, see pic attached.

Also attached is a pic of the DT29E relay box/ base unit wiring diagram. I think the bottom two diagrams are for a motorised valve, and frostat, right?

I have taken the power for the relay box from the switched spur. I've connected 'LR' on the boiler, to 'A' on the relay box, and Ns on the boiler to B on the relay box.

I'm really not sure this is correct, but from google searches, this is what I've come up with.

So, before I put the fuse back in the spur and switch on, can someone offer their advice pls?

I'd suggest you keep the fuse pulled out and call someone who knows what the fook they're doing..

That's so WRONG. Do NOT replace the fuse/

 

[D_Hailsham]

The correct wiring is:

Connect Ls to A
Connect Lr to B

That's it. C and Ns are not used.

(You got the power side right.)

Thanks D_Hailsham

now up and running

That was very sensible advice.

At least he responded and stopped you completely ******* your pcb, if nobody had answered you might have switched it on, steelmasons probably saved you a couple of hundred pounds.
