The Back of The Thermostat Body
Turn the thermostat body over. On the back are
the 3 “AA” Energizer® alkaline batteries.
The “AA” Energizer® alkaline batteries provide
powertothethermostatwhenthe24VACpower
is interrupted (for example, when you remove
the thermostat from the wall for programming).
Fresh batteries will maintain the stored program
for approximately a year. If power loss is long
enough for the program to be lost, the thermo-
stat will automatically return to the factory pro-
grammed temperatures (64°F heating and 82°F
cooling) when power is restored. You must
reprogram the thermostat if this happens.

the programmed 70°F temperature is

OPERATING FEATURES
Now that you are familiar with the thermostat
display and buttons, read the following informa-
tion to learn about the many features of the
thermostat.
The thermostat is configured at the factory
so that this feature is disabled. If you wish to
have this feature, refer to the installation
instructions for this thermostat, or contact
your local heating/cooling contractor.
• COMPUTED ENERGY MANAGEMENT
RECOVERY (EMR) — The thermostat’s
microcomputer can be set to automatically
calculate the time it will take to change the
temperature to the next program setting.
Then the thermostat will activate the heat-
ing or cooling system to change the tem-
perature so that the desired temperature is
reached at the beginning of the next pro-
gram period. As an example of this feature,
assume that you have programmed your
thermostat to provide an overnight heating
temperature of 62°F, and that during the
next program period, beginning at 6:00 AM,
• TWO HOUR TEMPERATURE OVERRIDE
— Press
or
until the display
shows the temperature you want. The ther-
mostat will override current programming
and keep the room temperature at the se-
lected temperature for two hours. After two
hours, the thermostat will automatically re-
vert to the program.

• LOW BATTERY INDICATOR — The three
“AA” alkaline batteries will maintain thermo-
stat programming for approximately one
year if power to the thermostat fails. The
word BATTERY will flash on the display if
the“AA”alkalinebatteriesarelowandshould
be replaced. The thermostat will also make
a beeping sound every five minutes when
batteries need replacing. To override the
beeping, press any button on the keypad.

pressing any button on the keypad. After

possible to ensure that programming will
not be lost in the event of a power outage.
You should also change the batteries at
