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.)  
Programming Thermostat  
When you program the thermostat, set one  
schedule for weekdays and another for  
weekends, because your temperature require-  
ments 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.  
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.)  
Four time periods are available during week-  
days—WAKE, LEAVE, RETURN, and SLEEP.  
View these periods individually on the display  
when you press the Set Schedule key.

69-0786—2  
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.)  
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.  
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.)  
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.  
Fill in the times and temperatures you desire  
for weekdays and weekends. If you decide not  
to program the thermostat, it automatically
