 "summary": "The IAQ program runs Desert Aire's outdoor-air units with an energy recovery wheel, supply and exhaust fans, up to four compressors and condenser fans, and CO2 measurement. The BACnet list is short: an occupancy command, a remote reset, supply air and zone air setpoints, sensor and command readbacks, and integer status, CO2, pressure and alarm code objects. There is no network on/off command.",

  "BV 3 Alarm Active is inverted: 0 = alarm, 1 = normal.",
  "The list gives many analog values 'in tenths' (and some integers in thousandths); check whether your BMS reads 72.5 or 725 and scale if needed.",
  "The source lists instances 1001 and up as type \"INT\" and does not say which BACnet object type that is. They are shown here as AV, but Desert Aire does not confirm that; check the actual object type with a device discovery before mapping.",
  "Desert Aire does not name the product series on this list; it covers units that run the IAQ program.",
  "The source does not say whether the unit uses BACnet IP or BACnet MS/TP.",
  "AV 23 VS Low Oil Speed Setting is a variable-speed compressor setting, not an everyday BMS point."
