 "summary": "Wilo's SC-family switch boxes control multi-pump systems and act as a BACnet MS/TP slave on their RS-485 port; BACnet IP needs an added gateway in the panel. The SC Fire D APSAD list covers the operating command, fire-pump switch states, battery/engine or mains values and fire error bits. Fieldbus write access is governed by a bus command timer that must be refreshed every five minutes.",

  "Taken from the 'SC Fire D APSAD' table in Wilo's SC BACnet supplement (English part, pp94-95). Wilo prints a 'BACnet ID' and an object type with its BACnet type code in brackets, e.g. 'Analog Input (0)'. The ID is used here as the instance and the type follows the code, so rows printed 'Binary Input (4)' are Binary Outputs.",
  "Where Wilo prints several IDs against one name (pump state, switch box state, error state and other bitmaps), each ID is its own binary object for the element printed beside it; the element is shown in brackets after the name.",
  "Analog objects that list several units report in the unit of the active control mode.",
  "Wilo prints 'Error state' and 'FC state' rows with no BACnet IDs or elements in this table; they are left out.",
  "The E, D and ED suffixes in the switch-state and fire-error names mark electric, diesel or both variants, as printed."
