 "summary": "The 40VM900052A BACnet Interface connects up to four XYE ports of Carrier 40VM VRF systems to BACnet IP and presents every indoor unit as its own BACnet device with 36 objects: inputs for room and set temperature, mode, fan speed, lock and alarm status, and outputs for on/off, mode, fan speed, setpoints, vanes and lock settings. Outdoor header units appear as separate devices with their own list.",

 "notes": [
  "Each indoor unit is a separate BACnet device; its device ID is NNNPAAA: NNN = the interface's virtual BACnet network number, P = XYE port 0-3, AAA = indoor unit address 0-95.",
  "The object table prints the output names with a zero (IDU_A0_, IDU_B0_, IDU_M0_); the per-object sections of the same manual spell them IDU_AO_, IDU_BO_, IDU_MO_, which is used here.",
  "Access is inferred: the manual describes the outputs as readable and writable and the inputs as read-only.",
  "State texts are from the object property tables; MO 1 lists AUTO as Reserved on indoor units that do not support automatic mode. Binary objects use off/on text.",
  "AI 8 is the outlet air temperature or T2 temperature, depending on the indoor unit."
