IMPORTANT
Although the thermostat has a low
battery indicator, replace the batteries
once a year to prevent the thermostat
and heating/cooling system from
shutting down due to lack of battery
power.
As a precaution, when leaving home for longer
than a month, change batteries before you
leave to prevent the system from shutting down
due to lack of battery power.

Programming Thermostat
When you program the thermostat, set one
schedule for weekdays and another for
weekends, because your temperature requirements probably vary. (During weekends, only
the WAKE and SLEEP time periods are
available.)
Use the personal Program Schedule for
planning your program schedule of time and
temperature settings for various times of the
day.
Four time periods are available during weekdays—WAKE, LEAVE, RETURN, and SLEEP.
View these periods individually on the display
when you press the Set Schedule key.
Select WAKE if you want the house at a
comfortable temperature when you get up,
while you get ready for work or school. When
deciding what time to set for your WAKE
period, include extra lead time, depending on
the outside temperature and your furnace
response time, to give the furnace a head start
to heat the house before you get up. (This will
be a higher temperature during heating
season, or a lower temperature during cooling
season.)
Select LEAVE if you want an energy-saving
temperature while you are away at work or
school. (This will be a lower temperature during
heating season, or a higher temperature during
cooling season.)

Select RETURN if you want the house at a
comfortable temperature for activities before
bedtime. When deciding what time to set for
your RETURN period, include extra lead time,
depending on the outside temperature and
your furnace response time, to give the furnace
a head start to heat the house before you
arrive home. (Again, higher for heating or lower
for cooling.)
Select SLEEP if you want an energy-saving
temperature while you are sleeping. (For more
comfortable sleeping, some homeowners
choose not to raise the cool temperature during
the night.)
Fill in the times and temperatures you desire
for weekdays and weekends. If you decide not
to program the thermostat, it automatically
controls heating at 68°F (20°C) and cooling at
78°F (26°C), 24 hours a day. Also, you do not
need to enter a time and temperature program
for all periods if your schedule does not require
it. For example, a house that is occupied
during weekdays would not require programs
for LEAVE and RETURN.
When pressing the keys, use the ball of your
finger or a soft pencil eraser.
NOTE: Using sharp fingernails or pencil
points can damage the keypad.
If you make an error at any time during
programming, press the Run Program key,
and continue again at the last step.
