four consecutive periods. They are Morning, Day,
Evening, and Night. Separate set points are provided for
Heat and Cool.

ming. It has four consecutive periods, which are inde-
pendent of the four temperature periods. The default set-

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
