 "summary": "Intesis 700 Series multi-protocol gateway set up for BACnet IP or BACnet MS/TP on a Samsung NASA bus. It publishes outdoor-unit alarms, gateway-wide commands and one block of objects per indoor unit at (IU x 100): on/off, mode, setpoint, fan, swing, room and discharge temperatures, error code, filter, remote restriction, ventilation, hot water, WindFree, 360 cassette airflow and energy consumption. This file shows the standard indoor unit (IU) set.",

  "Indoor unit instance = (IU x 100) + offset, IU 1-64; IU 1 is shown (100-117).",
  "Left out because they reuse instances of the IU set for other unit types: mode objects for HE, EHS/ERV+ and chiller units, AHU discharge setpoints, hot-water mode and setpoints, water temperatures and the slave-chiller error objects (see the manual).",
  "The outdoor communication-error object is printed with instance OU[0..15] + 1; outdoor unit 00 is shown at BI 1. As printed, OU 15 would land on BI 16, the OU Addressing Error object.",
  "OXXUXX_Air Clean_C (Binary Output) is printed without an instance offset and is left out; OXXUXX_Air Clean_S is BI 107.",
  "Mode numbering here is 1=Heat, 2=Cool, 3=Fan, 4=Dry, 5=Auto, unlike the older INBACSAM manual. Consumption is Wh or kWh as set in MAPS.",
  "The BACnet table has no read/write column; access is inferred from object type. Replaces the INBACSAM004O000-064O000 BACnet servers (listed separately)."
