Boss therm bps242rf wiring problem

[Casgas]

Wiring a boss therm bps242rf programmer into a Worcester Bosch 30 cdi and the wiring diagram is rotten.
Any help would be really appreciated.

The transmitter has terminals labeled, Live, Neutral, L1,Lx and L2.

On the boiler there is a Lr, Ls and Ns.

Please help!!

Lx is common and L1 is switched live/boiler on. Ls is live sent/common and Lr is live returned/switch live boiler on. boss therm will need permanent live and neutral in the top of the receiver, shouldn't need earth as is double insulated (as per installation book)

So remove the link between Lr and Ls, then Lx to Ls and L1 to Lr?

Thanks for your reply

Yes and Ns to neutral and link Lx to live on programmer. make sure there is an earth run in the cable and connected in the boiler even if not needed at the receiver.

Ns to Neutral on the boiler? I'm heading to try it out just now so fingers crossed.

NO, Ns on the boiler to Neutral on the receiver!
