Yup, thanks for the comments/suggestions...

I think I will endeavour to make all the connections outside the boiler
casing... it's just going to be so much easier to work with I think... -
obviously just need to contrive a suitable enclosure / terminal block
arrangement...

I'm not after energy saving from this exercise, and separate zones really
doesn't make a great deal of sense in this house (I have TRV's almost
everywhere anyway, so I can turn off the individual rads in the (very few)
rooms we rarely use (that pretty much only applies to the 3rd bedroom).

What I am after is just a modicum of intelligent control over the central
heating on & off functions... so that I can for instance:

Have the heating turn off automatically when I leave the house & arm
the
alarm system - even if that occurs during a programmed on time
Dial in from my mobile whilst on the way home & turn the heating on in
advance of my arrival
Turn the heating on/off from a iPhone/iPod/iPad (I have all 3!) and or a
CBUS switch outside of the programmed times
Not have to remember to go & manually disable the heating when I go
away on
hols for 2 weeks.. (never again sit on the plane worrying "Did I turn
the
boiler off?)

Using just the supplied functionality imposes a set "schedule" of
on/off
times as permitted by the built in time programmer, OR it requires manual
intervention (i.e. either me or SWMBO have to manually adjust the T-stat or
advance the program)... - (the number of times I leave a but earlier than
normal & forget to manually turn the heating off...)

If I decide to "bunk off" early from work one day and come home
before I
normally would, then I come home to a cold house, - nothing in the default
control package allows me any means of remote control from off the
premises...

Will see what the electrician says this evening...

Cheers.

Gareth's approach sounds good to me - nothing too controversial for a
plumber to suck his/her teeth over! I'd also suggest you want the
connections outside the boiler simply because only a Corgi/Gas-Safe
registered engineer is supposed to open the boiler. Of course Part-P
probably applies to the wiring too :(

I'm not sure how much benefit you'll get from a simple on/off automation -
probably not much from an energy saving perspective anyway - so it may not
justify too much effort. If you could add some zone valves and get multiple
zones with independent control that should give better savings as you can
only heat areas when they are occupied.

What I have is the old timer stat still, but the switched signal goin=

of the boiler goes through a 2 gang, 2 way light switch. When up, the=20

wires are connected to the old timer and it's programming. Flip them down,=

and the feed is now handled through a CBUS relay.
