Setting the carbon dioxide limit
The carbon dioxide limit is the limit value for the carbon dioxide level. Once this limit is exceeded, the ventilation unit will boost the ventilation. If more than one carbon dioxide sensor is used, the fan speed is adjusted using the highest sensor value. The carbon dioxide sensor is optional.
Note:
The indicative maximum carbon dioxide level in the indoor air is 900 ppm.
Other values relating to the carbon dioxide level of the air:
- 1200 ppm — The limit value for satisfactory indoor air
- 700 ppm — The limit value for excellent indoor air
