I have found the information about the "smart" thermostat.  It
is (or was) sold by JS&A, Northbrook, Il. (800)-323-6400.  Are
they still in business?  I'm looking at a 1982 catalog.

Anyway, it's called the "Love/Hate Thermostat".  Named, I guess,
for its functionality and lack of, ah, beauty.  It is microprocessor
controlled, of course, and allows a whole bunch of setbacks settings
per day.  It even knows the difference between a weekday and the weekend.

Some interesting features (editted):

"You set most thermostats to the time you want the furnace to go on
in the morning.  But what if one morning it's bitter cold outside
and the next morning it's much warmer?  The Magic Stat senses and
computes the drop in temperature and the time it will take to get
your room to your exact wake up temperature.  The system also
computes the ideal length the furnace should stay on to keep the
temperature within a range of plus or minus one and one-half degrees."

The thing also has a "learn" mode.  You operate it manualy for a day
or two and it remembers your living pattern.  Sounds like one of
those Detroit robots, doesn't it?  Anyway, I think it represents
a perfect application of a microprocessor in a home.  Price: $80.00,
ceaper than some "dumb" varieties.
