Cause

Site scheduled a special day and the output did not function correctly. 

Resolution

If you have a special day defined in a DCU, there must be a special day schedule (S1 through  S7) defined for ALL the time schedules and controller points in the DCU. If a time schedule does not have a special day schedule defined, the point will remain at it last commanded state until the special day period is over.
