The wiring connections at your boiler should look like this.
There is a wire loop fitted between two of the X106 terminals marked '24V DC Room Thermostat'. Remove this link.
Connect the two terminals where the loop came from to Lx and L1 in the diagram below from the Siemens RCR10/433 Receiver instructions. It doesn't matter which way around they go.
Finally the RCR10/433 needs a 230V supply connected to its L and N terminals to power it. This should come from the same 3A fused connection unit supplying the boiler, and can be picked up from the boiler L & N, or the L & N terminals at the load side of the fused connection unit, whichever is easier.
You should use two separate cables for this. One for the 24v connections and a second one for the 230V supply.

blinding,thanks mate. was going to put a seperate fuse spur in for the receiver unit, so boiler can be isolated seperatly for maintence, thank you for you help, i was planning on doing that but wanted confirmation. wasn't sure whether to use the 24v stat or the 230v terminals.
