Issue
When an alternative holiday schedule is set up for "ON all day" or "OFF all day" the representation in the time schedule dialog and the operation is quite clear. However, when defining set hours of operation, it may not be clear when the unit is actually going to run.
Environment
- Vista Workstation
- Xenta Time Schedule
Cause
An alternative or holiday schedule (represented in gray on the time schedule dialog) will override the operation for the entire day, not just when the alternative time is scheduled.
Resolution
An example alternative event:
-
The unit is scheduled to run every day of the week from 8am to 5pm. On Tuesday, a special meeting requires that the unit run for an additional hour in the evening. The operator schedules the alternative event for 5pm to 6pm and the schedule dialog looks like this:
-
In reality, an alternative event will override operation for the entire day in which it is scheduled. Even though the time schedule display appears as though the unit will run any time the schedule is shown in white or gray, in reality, the operation will be as if the schedule was configured like this:
-
In order to properly schedule additional time to an existing time schedule, the original occupied hours must be accounted for in the definition of the alternative event. A correctly schedule additional hour is shown below:
