wireless stat grant combi

[ollie78]

hi. i need to wire a programmable wireless stat to a grant vortex external combi. The stat is a siemens rdj10rf.This is how i've started wiring it:
STAT BOILER
live = live
neutral = neutral
L1 = 1 Central heating

I've got LX common and L2 changeover contact left in the stat
and hot water 2 in the boiler. i was thinking i should link hot water 2 to live which should give me water on demand and not on timer. But that leaves lx and l2 in the stat.
hope u can help..

thanks for the quick reply, i'll post a pic of the boiler wiring diagram to a similar stat. due to it being an external boiler everything is pre wired except for the stat. boiler comes with an isolating plug which has HW CH LIVE EARTH NEUTRAL, this is were you wire the stat and the mains feed.
Let me know what you think.
Cheers
