Unscheduled_Operation
This algorithm evaluates trend data collected from an AHU unit. It determines if an AHU unit was running at an unscheduled
time. It returns true if the facility is unoccupied, the command was given to turn the supply fan on, or the supply fan is
on. It does not matter how long the supply fan was running. A false result indicates that the AHU ran on schedule.
This algorithm might produce false positive results if the system activates while unoccupied to maintain unoccupied setpoints.
