 "summary": "The 8631-CRC controls clean room pressure by modulating supply and exhaust dampers, with a second pressure sensor and two supply flow inputs for monitoring. With the BACnet board it is a BACnet MS/TP device exposing pressures, flows, damper positions, the pressure and supply setpoints, alarm limits, a Status Index alarm code and an emergency mode command.",

  "Units follow Units Value (MV 2): 1 = ft/min, 2 = m/s, 3 = in. H2O, 4 = Pa. Flow is cfm in English mode and l/s in metric mode.",
  "The ranges for Pressure Setpoint, Low Alarm and High Alarm are printed as \"-0.195000 to -0.19500\" and are kept as printed."
