It is possible to set the RMZ792 bus operator unit to search for bus devices in
specified areas and lines. Bus devices in areas and lines other than those defined
in the search criteria must be added manually.
Note: The RMZ792 bus operator unit only recognizes Synco 700 bus devices,
including the OZW77x central communication units and the RXB/RXL room
controllers.
