The Back of The Thermostat Body
Turn the thermostat body over. On the back are
the 9 volt Energizer® alkaline battery and the
option switches.
1. The 9 volt Energizer® alkaline battery pro-
vides power to the thermostat when the 24

you remove the thermostat from the wall for
programming). A fresh battery will maintain
thestoredprogramforapproximatelyaweek.
If power loss is long enough for the program
to be lost, the thermostat will automatically
return to the factory programmed tempera-
tures (64°F heating and 82°F cooling) when
power is restored. You must reprogram the
thermostat if this happens.

period, beginning at 6:00 AM, you have
programmed a temperature of 70°F. The
thermostat will automatically activate the
heating system at about 5:00 AM, so that
the programmed 70°F temperature is
reached by about 6:00 AM.
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.
• COMPUTED ENERGY MANAGEMENT
RECOVERY (EMR) — The thermostat’s
microcomputerautomaticallycalculatesthe
timeitwilltaketochangethetemperatureto
the next program setting. Then the thermo-
stat will activate the heating or cooling sys-
tem to change the temperature so that the
desired temperature is reached at the be-
ginning of the next program period. As an
example of this feature, assume that you
have programmed your thermostat to pro-
vide an overnight heating temperature of
62°F, and that during the next program

the system from heating to cooling as
needed. First you must move option switch

In the AUTO mode, the thermostat will not
allow the temperature separation between
the highest heat setting and the lowest cool
setting to be less than 1°F. For example, if
the highest heat setting is 76°F, the lowest
cool setting cannot be below 77°F (see

To operate properly in the AUTO mode, there

the HEAT and COOL modes. See PRO-
GRAMMING YOUR THERMOSTAT.
4. What happens if the electricity goes off
or is manually shut off?
6. What can cause the thermostat display
to freeze or go blank?
If you have not installed a 9 volt alkaline
battery, the display will go blank and the
program will be lost in five seconds. When
electricity is restored, the thermostat will
maintain a heating temperature of 64°F and
a cooling temperature of 82°F until you
reenter your program. Setpoint tempera-
ture will not be displayed.
A completely blank display may indicate
that power has been lost to the thermostat
and the backup battery is also dead. How-
ever, if there is power to the thermostat and
the display is blank or frozen, static dis-
charge is probably the cause.
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.
If a fresh 9 volt Energizer® alkaline battery is
installed, the program will be maintained for
about one week with no 24 VAC power
present to the thermostat. See OPERAT-
ING YOUR THERMOSTAT.

To correct this, remove the thermostat from 7. Why won’t the setpoint temperature go

SYSTEM
to the temperature I want?
In the AUTO mode, the highest heating
setpoint temperature you select must be at
least 1°F lower than the lowest cooling
setpoint temperature you select (for ex-
ample, if 70°F is your lowest selected cool-
ing temperature, you cannot select a heat-
ing temperature any higher than 68°F). If
such a conflict exists, set the lowest cooling
temperature higher in order to set the heat-
ing temperature higher. To set a lower cool-
ing temperature, you must select a lower
