This feature provides a method to program every day with
the most popular time and temperature profile using one key

options (AS Cool or AS Heat) should be set on in the
installer configuration.
Select the desired Comfort Temperature in the setpoint.
When the Auto Schedule touch key is pressed, it will start
flashing indicating that it is now ready to insert the displayed
temperature setpoint as the Comfort Temperature for the
selected system mode currently in (Heat/Cool). A second
press of the Auto Schedule touch key will complete the
process. A 6 o F setback temperature will also be inserted for
the night step. Once it is done, the touch key display Auto
Schedule will disappear disabling any further operation of
Auto Schedule touch key. If desired it can be enabled again
in the installer configuration menu.
Entering Fan Program
The FAN touch key is used to select FAN Auto operation
(fan energized with a call for cool but not on with a call for
heat) to FAN On (fan on continuous) or FAN PROG (fan
programmed to cycle fixed time automatically). Each press of
the FAN touch key will change the mode from Auto to On to
Prog. FAN Auto or FAN On or FAN On Prog will display in
the run mode for as long as the fan is in that position. When
FAN Prog position is selected and the system is in the Cool,
Heat or Auto mode, the circulator blower (fan) will cycle ON
for 10 minutes, OFF for 20 minutes when the thermostat has
not called for cooling or heating for the past 60 minutes.
To improve indoor air quality, the system circulator can be
programmed to run during any program time period by
touching the FAN touch key in the appropriate program time
period when in the Menu mode for that particular day.
The display shall indicate Prog (under the FAN icon) when in
Menu mode and the fan is programmed to come on during
that time.
In the menu mode, each time the fan key is pressed, the fan
operation and display will change from FAN Auto to FAN
Prog. The display shall indicate FAN On Prog when in run
mode and the fan is programmed to run for that particular
time period.
When in Run Schedule mode and the FAN touch key is
pressed, it will override the schedule, and the display and fan
operation shall change to FAN Auto and the fan is stopped.
Further key depression will change it to FAN On (continuous
blower on) and to FAN Prog (cycling 10 minutes on and 20
minutes off if there is no call for heat or cool for 60 minutes).
The Run Schedule touch key will also be indicated, meaning
that it is an override on the scheduled program. The override
will last until next schedule comes up or the Run Schedule
touch key is depressed.
