Wiring from Honeywell T40 Thermostat to Salus thermostat

[harrold17]

Newbie here, so apologies if my Forum etiquette is not the best

So I'm replacing my Honeywell T40 thermostat with a wireless Salus (RT310RF) version, but I just want to make sure I'm getting the wiring right.

The existing wiring for the Honeywell is;



with the current wiring as below;



The wiring diagram for the Salus is as below;



So I'm just wondering how I would wire the Salus up, with the wires I have?

I have it in my head that on the Salus;

Black = N
Brown = L
Grey = NO
+ link from COM to L

Does this sound correct?

Many thanks

Yes, that's right.

Ok, so I've finally got round to doing this!

I wired up my Salus (RT310RF) as above, but it's not working

There doesn't appear to be any power getting to the unit, as the power LED is not lit (and the receiver is showing no 'signal').

Any ideas?

Thanks

I changed to a digital stat. Got a local spark to do it in the end as i only needed 2 out of the 3 wires. He explain it to me and basically it's a light switch on or off as stat was run from the battery power. With you having a wireless reciever you need to power that with a constant live i guess.
