Fan calibration
Fan calibration is not required for KWL Yoga ventilation units. However, the

The function is available when an Air Quality Sensor (CO
installed. 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 sensor-
controlled operation.
