Aren't we talking about a programmable stat, which does *both*
timing *and* temperature control in a single device?

Even if we are still having a conventional controller in series is
handy as most programmable stats are not easy to manually force off by
a single button push or three, where as programmers are.

In 7 years of having a programmable stat on our system I can't say I've
ever noticed that desire. If I want to turn the system off for some reason
then I use the boiler controls. (as it happens there is timer as well in
the circuit as the boiler has one built in, but I never touch it)

Also if you
have noisey pipework it can be a bit annoying having the heating come
on at 0300 just beacause the house has sunk below 15C. Heat it when
you need it not just because some dum stat says so.

The Sat would only be saying so because that is how you had programmed it

If you don't want the heating to come on in that situation you would set a
lower temp for that time period
