Hello and Happy New Year!
Just before the Festive Season we had a power cut and our Honeywell
ST699 central heating timer reset itself. I imagine there is an old
NiCad battery in there which has popped its clogs. I am thinking that
this would be a good time to replace this 24 hour timer with a 7 day
timer.


Unless you really want to replace it I'd fit a new battery and spend
the money on a programmable thermostat.


Hmm. I hadn't thought of that. It sounds like it might be a bit too
sophisticated for our requirements, though.

Not really - the two work very well together. The ability to set different
temperatures for parts of each day and except the weekend if needed are a
big energy saver. And the timeswitch will still switch things on and off
totally if that's what's required.

I'll bear it in mind for
the future. At the moment, I'm looking to get something done for the
short term in case of the combined effects of a power cut, a cold snap
and us being out - so our pipes don't freeze and burst.

The battery failing shouldn't stop the thing working - it's only a backup
for when the mains fails.
