A multistate schedule controls a device that has output states based on integers or positive whole numbers including zero.
For example, you can create a multistate weekly schedule that is bound to a multistate value to control an air handler unit in an office building. To regulate the air circulation Monday through Friday from 08:00 to 17:00, you can set the value to 2 (occupied) when the schedule is active and 1 (unoccupied) when the schedule is inactive.
