Default CM67 Optimum Start algorithm

As some will remember, with the groups useful advice I fitted a CM67RF to
my existing system a few weeks back. It's transformed the level of control
and refinement compared to before (a TRV only system) but if like me you

are
new to these types of stat it does take a bit of mind set change to get

the
best out of programming the device e.g. one error I made was to set the
target temp time too early because I was thinking along the lines of

giving
the house a chance to warm up before getting up. The CM67 started the

system
up in the middle of the night. A bit of tweaking sorted that.out.

I've not changed the factory settings but like most tuning (bikes, cars,

IT
systems etc.) I'm going along the path of changing one user setting at a
time and checking the results over the next or so. I may move on the

factory
settings but I doubt it.

And I fitted one just after Jules (after tapping you lot up for info). It
has totally transformed our house. It feels comfortable ALL the time now!


Are these things ever advertised? I only learnt about the existance of
programmer/thermostats where you can vary the temperature during the day from
earlier posts in this ng. I have always wanted such a device so when I learnt
that they existed I ordered one from plumbworld.

Installing and using the device has made me realise how slowly my house responds
to temperature changes. Maybe 1C /hour either up or down.
