 "summary": "The AVC6000 is a valve-mounted airflow controller for lab supply, exhaust and fume hood valves, on BACnet MS/TP. It reports measured airflow, valve position and the active setpoint; in fume hood mode it adds face velocity, sash position, hood alarms and purge. The airflow setpoint can come from an analog input, dry contacts or a BACnet AV, and MSI 2 shows which mode is active.",
