4.4. PROGRAMMING
You can change the preset time/and temperatures to suit
your schedule for each day of the week. Each day has
four consecutive periods. They are Morning, Day,
Evening, and Night. Separate set points are provided for
Heat and Cool.
Fan programming is similar to temperature program-
ming. It has four consecutive periods, which are inde-
pendent of the four temperature periods. The default set-
ting for your systems fan requires it to run only as
required by your environmental system. It may be pro-
grammed to maintain a minimum run time on an hourly
basis, or run continuously.
4.4.1 WEEKDAY TEMPERATURE PROGRAMMING

There is a minimum value that must be maintained
between the heat temperature set point and Cool temper-
ature set point. The value that must be maintained is
called the Deadband. It is programmable and may be
changed in the Installer Setup menu. If you move the
heat set point temperature to close to the cool set point
temperature the cool set point temperature will move
away from the heat set point temperature to maintain the
dead band. Conversely the heat set point temperature will
move if you adjust the cool set point temperature to
close. There are programmable limits for both heat and
cool, which you will not be able to exceed. These values
are accessible from the User Setup Menu.
