5. How can this thermostat save
energy when it comes on and
off so many times early in the
morning hours?
Two ways. First, it
saves
energy (and money) by
setting back
the temperature
for
blocks
of time during the day or night. Second, it
conserves
energy by
recovering gradually
to the desired temperature. This prevents
overshooting
your comfort set point (and wasting energy) or
undershooting
the comfort set
point (and forcing you to change the thermostat setting, also wasting energy).

4. How long does the HOLD key
hold?
Forever! The HOLD key will hold the temperature indefinitely. The only way to
release it is to push the RUN PROGRAM key or change the system switch
positions if applicable.
6. Why don’t all thermostat
models have AUTO (auto-
matic) changeover from
heating to cooling?
Most parts of the country don’t have wide temperature swings during a 24-hour
period, so it is not necessary. Desert climates, such as Phoenix, are the
exception because of wide variations in temperature that may require both the
air conditioner and furnace to run during different times within a given 24-hour
period.
7. Sometimes my Chronotherm
III Thermostat doesn’t allow
the house temperature to
drop to my SLEEP setting
before it starts bringing the
furnace on. Why?
When you start your SLEEP period, the thermostat will turn off your furnace and
your house temperature will start to fall. After that, the thermostat does nothing
until the house temperature falls all the way to your SLEEP temperature setting
or until recovery starts.
In mild weather or with good insulation, your house temperature may not fall all
the way to your SLEEP temperature setting and the thermostat won’t turn on
your furnace until the time to recover back up to your comfort setting.
