 "summary": "The GO3 is a Greystone CO2 sensor for grow rooms and greenhouses, with native BACnet MS/TP. CO2 and the optional temperature and RH readings are Analog Inputs; altitude, relay setpoint, hysteresis, delay and offsets are Analog Values, and the relay state is a Binary Input. Its device object name defaults to \"CDD CO2 001\".",

  "Points from the object table in section 1.1 of the setup guide.",

  "Temperature, RH and relay objects report a fault when those options are not installed; BV 2 only works with the auto-cal sensor.",
  "Access from the object pages: AV and BV Present_Value are read/write."
