Manual Programming
■ Your thermostat can be programmed for weekdays and weekends, or have unique
programs for all 7 days. Use Weekday /Weekend Programs or 7-day Programming 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.
■ 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 set point, and the Cool
set point can not be set lower than the Heat set point.
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 Recovery will determine
how early to turn your system on, so that the room is comfortable at the program time.

Auto Season Changeover
When the System Selector is in AUTO position , the thermostat will automatically
change between Heating and Cooling systems, depending on your program. We
recommend keeping your programmed heating and cooling temperature at least 4˚F
(2˚C) apart to allow the Auto Season Changeover to occur when the appropriate
temperature span has been reached. However, if your heating and cooling programs set
temperatures are close, there is a built-in program to prevent the thermostat is in
Temporary, a Designated Day Override or Permanent Override, as these overrides are
energy saving settings. Auto Season Changeover will still function in Home Today mode,
as this is a comfort setting.
For example, you may have the following temperatures programmed at a given time:
Heat Set Temp=68˚F, Cool Set Temp=78˚F
If the room temperature rises above 78˚F, then the thermostat will automatically change
to cool mode and turn on the air conditioner.
Likewise, the thermostat will automatically change to heart mode and turn on heat when
the room temperature falls below 68˚F.
HOME TODAY
This patent pending feature allows you to quickly and Temporarily Override your energy
saving program setting on days when you are normally away from home with one key
press.

current time.
■ When pressed during the day, the thermostat will remain in Home Today mode
until the first program of the next day.
■If the system is changed between Heat and Cool modes (either manually or by
Auto Season Changeover) during the “Home Today” override period, the setpoint
temperature will be automatically update. It will automatically change from the lowest
cool program setpoint to the highest heat program setpoint.
■ Press to exit Home Today mode before the schedule ending time. ”HOME” is
no longer displayed on the LCD screen, and the thermostat returns to the current
program.
■ You can manually change the setpoint temperature while in Home Today mode.
Refer to the Temporary Manual Override instructions .Manually changing the set
temperature while in Home Today mode will not affect the Home Today ending
time, However, the set temperature will not change automatically with a manual
