The Church heating consists of three boiler systems, two of which have
3 and 4 zones respectively. This means I have two clusters of timers
(controlling the boiler via motorised valves) which is not too much of
a problem but it would be nice to have one for each of the boilers.

It would also be nice to have remote "boost" buttons so users of rooms
can request heat for an hour or so (when I have forgotten to programme
it in) and preferably for the boost button to have an indication when
that zone is on.

Any suggestions of products available or am I going to have to look at
a homemade system?

Greeting from another church heating person! You can screw up most jobs
in a church and people will be too polite to say anything but get the
heating wrong ....

Fortunately we only have one zone, with three Honeywell CM67s doing
different jobs. I doubt whether you can afford this, but I was at
EcoBuild on Thursday and reminded one of the Honeywell reps that a couple
of years back I had said to one of his colleagues that what I really
wanted was a CM67 with an internet connection so I could check or
reprogram it from home, whereupon he gave me a demo of their latest
system which does this for multiple zones, with remote control over the
net possible.

I couldn't find any prices though - rep suggest low four figures.
