 "summary": "The 8631-HC controls hospital isolation room pressure by modulating an exhaust damper, switching between negative, positive and no-isolation modes. With the BACnet board it is a BACnet MS/TP device exposing room pressure, active setpoint, flow, damper position, the negative and positive setpoints, alarm limits, a Status Index alarm code, the control mode and an emergency command.",
