 "summary": "The Intelli-Hood IH3 System Controller is the main BACnet IP device of the older Intelli-Hood 3 kitchen ventilation system and a virtual router for the fan and hood devices behind it. Its own object list is small and read-only: the state of three digital inputs, two dry-contact outputs, two 24 VDC outputs, and the analog input and output as a percentage. It differs from the IH4 System Controller (three inputs here instead of four, and only one analog input and output).",

  "The exhaust fan, auxiliary airflow, hood controller and virtual I/O devices of the IH3 have the same object lists as the IH4 versions already in this library.",
  "Supported BIBBs: DS-RP-B, DS-RPM-B, DS-WP-B, DM-DDB-B, DM-DOB-B; B-ASC profile, no segmentation."
