 "summary": "NOVOS 3 and NOVOS 5 are wall-mounted room sensors and operating units with a BACnet MS/TP interface. They measure temperature and, depending on the variant, humidity, CO2 and VOC, and offer occupancy, setpoint and fan-stage inputs for the room controller in the BMS. Only the main operating values are BACnet objects; the rest is set through a configuration file written with Thermokon's uConfig tool.",

  "Which AI objects are present depends on the sensor variant (Temp, CO2 Temp, CO2 Temp_rH, CO2+VOC Temp, CO2+VOC Temp_rH).",
  "The icon objects (BV 16-27) apply to the NOVOS 5 LCD; the LED objects (MV 426-427) to units with an LED button.",
  "Temperatures switch to °F when the unit system is set to imperial in uConfig.",
  "The manual has no access column; R/W here is inferred from the descriptions."
