On Worcesters you should have your supply into L & N and E connected to earthing stud. Then Ns is a spare neutral to take to external clock/stat. Ls is the switch live out and Ls is the switch live return (eg. switch pair) Ls/Lr are probably linked - take link out. If in doubt most instructions are online.
