The CVAHU normally uses its own Real Time Clock and an
Internal Week Schedule to determine the Occupied/
Unoccupied mode of operation. The CVAHU does have the
ability to use a Global Broadcast from another scheduling
device on the communications loop if a different schedule is
required. If an external schedule is used, the range of schedule
numbers is one to eight.
