Your thermostat consists of two parts: the ther-

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.

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

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.

can hold any temperature within its range
for an indefinite period, without reverting to

Whenever adjusting anticipation, increase

• 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

always change the batteries as soon as
possible to ensure that programming will
not be lost in the event of a power outage.
You should also change the batteries at
least once a year.

However, you may use the same heating

time periods. Also keep in mind that, for any
given day, you can only program one set of
times for both heating and cooling (for ex-
ample, if you select 5:00 AM to begin heat-

period 1 for Monday will also begin at 5:00

You may only program heating temperatures you have selected
into the heating program and cooling temperatures into the
cooling program (for example, you cannot program the COOL A
temperature into your heating program). You may program the
temperatures you choose in any order, and you may use the
same temperature in consecutive program periods (for example,
you may program period 1 with temperature B and periods 2, 3,
and 4 with temperature A). You do not have to use all possible
temperature choices (for example, you may want to select
temperatures for HEAT A and HEAT B only – in this case, the
HEAT C and HEAT D temperatures would stay the same as
previously programmed).

6. What can cause the thermostat display
to freeze or go blank?
A completely blank display may indicate
that power has been lost to the thermostat
and the backup batteries are also dead.

replace it on the wall.
During periods of low humidity (especially
during cold weather), you may feel or see a
spark discharge when you touch the ther-
mostat. This may cause the program to be
lost or the thermostat to display incorrectly.
To correct this, remove the thermostat from
the wall and disconnect the batteries. Wait
about two minutes, then reconnect the bat-
teries. The thermostat will revert to the fac-
tory preset program until you reprogram the
thermostat. If you don’t want to reprogram

10. Why won’t the compressor turn on, even
though the thermostat display is func-

Either the compressor lockout feature is in
operation or the thermostat is not currently
