For visualization, modifi cation and control via Modbus it will be necessary to have
software suitable for this kind of communication. S&P will not provide specifi c
software for this purpose. The information provided on the Modbus registers al-
lows establishing a correct communication between AIRSENS RF CO2 / VOC / RH
and confi guration software chosen.
Basic connectivity features
Addressing: 1
Transmission speed: 19200
Parity: EVEN
Mode: RTU
Electrical interface: RS-485
Connector type: wiring D0 – D1 – Common
CALIBRATION / RESET
AIRSENS intelligent IAQ sensor incorporates a self-calibration algorithm that
allows adaptation to the environment. This adaptation could be prolonged for two
weeks until the reading is fi ne-tuned, and there may be periods of time with LED
diffuser in red. During this period it is necessary to keep the equipment powered
so as not to interrupt the self-calibration process.
Manual way to start a reset process is disconnecting power supply, wait at least
30 seconds and power again the electronic control. It is also possible to do re-
motely via Modbus communication using General reset (register number 3).
