Aren't we talking about a programmable stat, which does *both*

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. 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.
