drayton scr receiver installation

[dava12]

Hi all, I am trying to connect my new drayton 3fr SCR receiver to my baxi boiler. As I understand it you take a supply from the mains connectors on the wireing centre of the boiler to the SCR unit you have positioned on a wall and take the jumper lead out of the wireing centre of the boiler and replace it with wires to the SCR but I do not know which terminals these wires go to on the SCR. Both wires in the boiler wireing centre are black and I have N L 1 2 3 4 terminals in the receiver back plate

you need to look at the instalation intructions for the stat.

Normally id have done it in 5 core,PL,N,C,SL,E.

The two blacks are Common(live out) and Switch live(Live in).

The controller will have the same but might be termed L1,L2 you need to see on the diagram which term is the C and which is the SL.

Run another 3 core flex from boiler to rf stat and put:

brown in left terminal at boiler - '1' at scr receiver
blue (sleeve brown) in 2nd terminal at boiler - '3' at scr receiver.
(you can put brown and blue either way around)

Earths to earths.
