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  
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.

year if power to the thermostat fails. The  
word BATTERY will flash on the display if

you may program period 1 with temperature B and periods 2, 3,

temperature choices (for example, you may want to select  
temperatures for HEAT A and HEAT B only – in this case, the

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.  
However, if there is power to the thermostat

begin the factory preset program. Or you  
may reprogram the thermostat, then re-  
place 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  
To prevent further static discharge prob-  
lems, touch another object to release static  
build-up before touching the thermostat.

though the thermostat display is func-

compressor lockout to expire. If the system
