Mains Live = L (RWB7) = L (RDJ10)
Mains Neutral = N (RWB7) = N (RDJ10)
Switch supply = 2 (RWB7) = Lx (RDJ10)
Switch supply to heating/boiler = 4 (RWB7) = L1 (RDJ10)

If you presently have a wire link between terminals L & 2 on the RWB7, you will also need a link between L and Lx on the RDJ10. If you don't have any link now, do not add one.
