Air quality test (respiration)
The function is available when an Air Quality Sensor (CO
2
sensor, humidity sensor) is installed in the extract air duct
or directly in the unit. This is only available with the optional AQS duct sensor (upon request).
If the air quality is better than the lower sensor limit value, the unit will be deactivated. After 10 minutes, the unit will
be operated for one minute at minimum speed to carry out another air quality test (respiration).
If the air quality is still lower than the lower sensor limit value, the unit will deactivate again. After 10 minutes, the
unit will be operated for one minute at minimum speed to carry out another air quality test (respiration).
If the air quality is higher than the lower sensor limit value, the unit will continue to run and slowly increase the
speed to the maximum value within 5 minutes. The unit will continue operating at maximum speed for 2 minutes.
During this time, the air quality sensor measurement value will be ignored. The unit will then return to automatic
