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.

Hi,
My choice is Vision Pro 8000(often it's over kill). Nice touch screen,
arm chair programming, Very accurate temp. keeping. I used to set it 5+2
day pattern. In summer or winter when we get up in the morning or come
home in the afternoon we never felt too cold or hot 'stat did the job
for us. Now I moved onto wireless one. I can move it to any area of the
house. I live in Southern Alberta where air is very dry particularly in
cold winter.
