Hope someone can help.
I want to wire a Siemens RF receiver to a Remeha Avanta 39c combi boiler. Below is the wiring diagram for the receiver.

Can anyone tell me what wires go where please? [/img]

The way i understand it.
4 to L and Lx
5 to neutral
1 to L1

Would this be correct?

And remove the link between 1 and 4!

Sorry, yes, the link i think is already removed because there's an existing faulty RF unit installed already (job for the weekend, haven't looked yet).

am i right in thinking that L2 is not connected to anything?

Yes.

Many Thanks for that.
The reason I'm changing it is because the reception with the existing unit barely carries through 1 brick wall. My parents have the Siemens unit and the signal carries no problem 30m through 3 thick stone walls, so fingers crossed I might be able to have the new thermostat in the front room (about 20m through 3 thin brick walls).
