You need to know where the other end of each wire goes before you can work out which connection does what at the prog end.

hi, i spoke to worcester today and they said live from Ls to the clock, neutral from Ns to the clock and switch flow to LR ....... on the back of the switch on the wall plate is N,L,1,2,3,4 i know that n=neutral,l=live but l-1 has a small wire going to it do i need to remove this wire / which one would be the switch flow return?

1 on the timer is the common, you need power to it to get power from the switched output, which is term 3, so you need to keep that link.
