 "summary": "The SureFlow 8682 controls a laboratory room by tracking up to four supply, two general exhaust and seven fume hood flows to hold a flow offset, trimming it to a room pressure setpoint, with reheat temperature control. Over BACnet MS/TP it exposes room pressure, every flow and the totals, the current offset, temperature, damper and valve positions, setpoints and alarm limits, occupancy, remote and emergency commands, and a Status Index alarm code.",
