For example, during the day while no one is home but the cats, we keep
the temperature set at 80°F. I arrive home at 5:00 p.m. and would like
to have the temperature at 75°F. when I arrive.

Rather than my having to "guess" how long it might take to reduce the
temperature by 5 degrees, is there a thermostat capable of figuring
that out?

Hi,
Most programmable 'stat has that ability. It learns the temp rise/fall
pattern after you program it. One example is Honeywell Vision Pro line.
Micro-processor within is little smart. Take a look at manual which you
can download .


Thanks, Tony. I've since looked at the range of Honeywell models, and
think model RTH2310 would easily suit my needs. Our schedule and lifestyle
doesn't require anything too sophisticated. It's a 5 + 2 program. Our M-F
would be consistently the same, as would our Sat-Sun, and this one would do
the job.
