26 PROGRAMMING
Programming
■ Your thermostat can be programmed for weekdays and week-
ends, have unique programs for all 7 days, or the same pro-
gram for everyday. Use Weekday/Weekend Programming be-
low, 7-day Programming on page 29, or Everyday Program-
ming on page 31 to enter or revise programs to match your
Personal Program Schedule.
■ Familiarize yourself with Manual Programming, so that you
can easily modify your programs as your comfort needs
change. Follow the steps below to change the program times
and temperatures.
NOTE: 1) The program time can be set in 10 minute incre-
ments, and remains the same for both Heat and
Cool programs.
2) The program temperature can be set in incre-
ments of 1 ° F (1 ° C).
3) The Heat setpoint can not be set higher than the
Cool setpoint, and the Cool setpoint can not be
set lower than the Heat setpoint.
4) If the system selector is in AUTO mode, the
current operating mode will be used for pro-
gramming.
5) After 15 seconds without a key press, the ther-
mostat will return to normal display mode.
6) When setting the program time, note the AM /
PM indicator.
7) With the Auto Recovery feature enabled, you do
not need to set your comfort program times
early. Auto Recovery will determine how early to
turn your system on, so that the room is com-
fortable at the program time.
