Wiring Instructions For Siemens RDJ10RF Room Thermostat

[cartman11]

Hi
Hope someone can help I need to wire the thermostat to my Baxi Duo Tec 28HE boiler but cant figure out the electrical connections
On the Thermostat I have the following

Live
Neutral
LX (common)
L1 (live feed to item to be controlled)
L2 (changeover contact)

I take it the live and neutral come from the fuse spur. but which connections do I use to the boiler?
Many thanks in advance

L1 and LX AND YEP L N fom fused spur you may find it easier to mount it on a single back box, tip wire the unit first as they are quite fiddly to wire in place.

An donnections 1 and 2 in your boiler . connection 2 of the boiller is the live out

Thanks
So am I right in thinking that the live out from the boiler goes to to LX on the thermostat and connection 1 goes to the L1

Wired as above and all sorted and working fine, thanks for your help

Hi sorry to jump into this conversation but I've got the same stat and boiler. Just to be clear I wire L N from the spur into the stat? Then the 3 core flex from the boiler goes where?

Thanks

Hi cartman11

Could you assist me in the same issue you had. Where are connections 1 & 2 that you mention? I only have a mains flex coming from the boiler at the minute.

Thanks
