 "summary": "The Ventostat T8000 BACnet series are NDIR CO2 transmitters with BACnet MS/TP on RS485. Four Analog Inputs give CO2, humidity and two temperatures; Analog Values hold offsets, relay setpoint and hysteresis, elevation, single-point calibration, baud and MAC; Binary Values switch temperature units and ABC Logic self-calibration and start a calibration.",

 "notes": [
  "The object table has no read/write column; Analog and Binary Values are listed as writable (settings and commands), inputs as read-only.",
  "Units are as printed in the table; AV 1, AV 5 and AV 7 point to footnotes (offset always °C, elevation always meters, baud in bits per second).",
  "Humidity, relay and thermistor objects only work if that option was ordered; the relay commands have no effect otherwise.",
  "Temperature units depend on factory options or BV 1; the temperature offset (AV 1) is always in °C and elevation (AV 5) always in meters."
