With this downlink, the automatic calibration or manual calibration can be turned on. How these can be set
is described here.
Byte 0 = 0x00: Automatic calibration off
Byte 0 = 0x01: Automatic calibration on
Byte 0..2= 0x02 nnnn: Re-forced (manual) calibration; nnnn is the calibration CO
2
value in PPM, converted
to hex.
Automatic calibration:
By turning on automatic calibration, the sensor will recalibrate itself in a week. It is important that the sensor
remains on continuously, otherwise the calibration may take longer.
The automatic calibration continues until it is switched off again with 0x00.
A manual calibration does not affect the on or off of the automatic calibration.
Note: When switching on/using automatic calibration, the CO
2
stoplicht must be
in fresh air (400
ppm)
for at least 1 hour a day
.
Most buildings have their air quality in order in such a way that usually once a day (during the night) the air
quality level is at/around 400 ppm.
Manual calibration:
With the manual calibration, a new calibration value can be set, this can be done by setting byte 0 to 0x02
and then setting a ppm value in byte 1..2.
Payload 0x01:
The automatic calibration is turned on, can be turned off with 0x00
Payload 0x020190:
The manual calibration is set with a value of 400ppm(0x0190).

Behavior settings
With this setting, the 'behavior' of the sensor can be determined.
The byte has a limited meaning:
0x01: LEDs are off
0x02: LEDs are on.
This is the default setting
Example:
Payload: 0x02 (binary:00000010): stoplicht mode is on and the LEDs are used.
