It is a combination boiler so there is no Hot Water control other than the
automatic operation when a tap is turned on. I assumed the timer merely
opererated the changeover valve and fired up the other burner. But I have
to
confess plumbing is not my expert subject so I could be well off the mark
there or just plain missing what you are warning me of :)

I was assuming that the timer bascially operates as a semi intelligent
switch to by locating the cable, the AD10 could use the appropriate wiring
to act as the switch rather than the timer.
/me wanders off to find a screwdriver... brb
