Time Programs
General Excel controllers allow equipment control based on time of day. For example, you
can set HVAC equipment start and stop times. Time programs implement this
control strategy. Each controller can have a maximum of 20 time programs.
The following figure illustrates a time program that controls lighting in a school.
Each time program specifies one weekly program. This weekly program schedules
the normal daily activity of the system by specifying which daily programs an Excel
controller should use for each day of a normal week (Sunday through Saturday).
Daily programs list points and point actions for the Excel controller to execute. The
points and point actions are called switch points. Daily programs with their switch
points are assigned to weekly programs to provide for automatic operations on
scheduled days.
An annual program applies the weekly program to each week of the year. The
controller operates according to the annual program.
To accommodate special events (such as unplanned conferences and after-hour
assemblies), a TODAY program can override a point action or switch point
