New thermostat

[drt1710]

Hi all, first post here, so howdy?

I've checked the wiki first, found a few similar probs but not extactly the same wiring.

Replacing a Honeywell T6360B room thermostat with a Salus RT300RF.

Honeywell had green/yellow, Blue, Black and red

Earth was to earth, blue to 2, black to 3, red to 1

Salus needs N, L, COM, and NO (N/O)

The Neutral and Live (Blue and Red) I'm fine with, but I'm left with a black wire, does it go to Com, or NO?

I'm also assuming I can do without the green/yellow earth cable?

Many thanks in advance.

Duncan

Blue to neutral
Black to no
Red to com

Many thanks for the speedy reply, however wiring up as you suggested does not even power the receiver up, no power light at all.

Cheers

Blue to neutral
Black to no
Red to com

Red should go to L; also insert a link between L and Com.

If the receiver still does not work, set the original timer to CH permanently ON.

Many thanks for that, the link wire did indeed fix the problem, all is working as it should now.

Thanks again
