Glossary
Comfort temperature
The temperature you want when you’re active and
occupying the room.
Energy-saving temperature
The lower (heating) or higher (cooling) temperature
that lets you save on heating and cooling costs when
you’re asleep or away. Also called the setback (heating)
or setup (cooling) temperature.
Preprogrammed schedule
This is the schedule programmed into your thermo-
stat at the factory. It sets a night program that provides
energy savings if you don’t set your own program, or if
your personal schedule is lost for any reason.
Maintaining Your Thermostat
REPLACING THE BATTERIES
Your thermostat uses three AAA alkaline batteries. We
recommend Energizer
®
batteries. The display will flash
“BAT” when the batteries get low. Unless the display is
blank (indicating the batteries are dead) when you start,
you won’t have to reprogram the thermostat if you can
insert the new batteries within 20 to 30 seconds of taking
out the old ones.
To replace:
■ Set the system switch to ARRÊT.
■ Remove the thermostat from
the wall. See page 14.
■ Lift the batteries out of the
holder.
■ Insert the new batteries, mak-
ing sure the positive (+) termi-
nals all face toward the right.
■ Replace the thermostat on the wall. See page 15.
■ Reprogram, if necessary.
POWER OUTAGES
Backup batteries will hold the programming and keep
the display on during most power outages. After the power
is restored, the system will resume normal operation.
If the display goes off when power is lost, either the
backup batteries need to be replaced or are not installed.
When power is restored, the display will flash 13:00 to
remind you to reprogram.

Program
The times and temperatures you set to define the com-
fort and energy saving periods for each day’s schedule.
Recovery
The time when the thermostat operates the heating or
air conditioning equipment to return the house from the
energy saving temperature to the comfort temperature.
The thermostat starts the recovery period early so the
house will be at the comfort setting by the time you’ve
chosen.
