greenstar wiring - frost stats and controls

[clearhead]

hi im after a wiring diagram please

ive got a worcester greenstar 18/25 combi
frost stats x 2 (sunvic txl?) not sure why 2 of them(high & low limit i guess)
acl drayton digistat 3 (programmable room stat)

boiler is working fine when external controls linked out

but not working when linked in
it will run off frost stat
has been fine for several months
but not now - only working on hot water
digistat is calling-re synched and new batteries (reciever is reconising it)
quiet happy to change frost stats to frost stat and pipe stat
(boiler in out building)
would like wiring diagram to suit
many thanks

sounds like the reciever is kaput, it might be recognising the signal from the room stat but not switching the relay.

Draytons are notorious for loosing signal. Some times you can re-bond them, but often you can't.
