Your thermostat can be programmed for weekdays and
weekends, or have unique programs for all 7 days. Use
Weekday/Weekend Programming below or 7-day Programming
on page 21 to enter or revise programs to match your Personal
Program Schedule. The same steps are used when entering
programs for the first time, or revising programs entered during
Auto Programming. 

■ 

When batteries are first installed, the thermostat has all 4 programs
set for 68°F (20°C) in Heat mode and 78°F (26°C) in Cool mode. 

NOTE: There are no energy saving time or temperature
settings until the thermostat is Auto Programmed or
Manually Programmed.

■ 

Familiarize yourself with Manual Programming, so that you can
easily modify your programs as your comfort needs change. The
example below demonstrates the Manual Programming method.

NOTE: 1) The program time can be set in 10 minute

increments, and remains the same for both Heat
and Cool programs.

2) The program temperature can be set in increments

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 programming.

5) After 15 seconds without a key press, the

thermostat 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 comfortable at the
program time.
