 "summary": "Belimo 22G gas monitors measure one or two gases and drive local relays and alarms. The -A and -B models have a BACnet MS/TP port that serves the local gas readings, ambient temperature, an auxiliary input and the alarm/relay states. With menu setting 46 = 2 one monitor also acts as a gateway and publishes the gas readings of every monitor on its CAN bus.",

  "Only the fixed objects are listed. With menu setting 46 = 2, each CAN bus monitor adds 'AV XYY - Gas reading XYY', where X = 1 for sensor A (top) or 2 for sensor B (bottom) and YY = the CAN bus address.",
  "AV 0 and AV 1 are for setting 46 = 1; AV 1 needs a second sensor.",
  "Each gas reading object carries the gas type and scale in its description.",
  "BACnet MS/TP is only on -A and -B models; -C models are CAN bus only."

 "integration": {
  "summary": "Turn on BACnet with menu setting 46, set the MS/TP address, baud and device instance at the keypad, then read the gas readings and the three alarm objects. Use setting 46 = 2 on one -A or -B monitor to bring a whole CAN bus network into the BMS.",
