The fan motor operates at 5 levels of airflow (revolution speed) as shown in the chart below.
In manual operation, use the fan speed button to run the fan at the desired speed – low,
medium, or high.
The airflow display lamps will light up in accordance with the fan speed selected.
In automatic operation, the fan operates at low, low medium, medium or high medium in
accordance with the situation in the room (cleanliness of the air) depending on the operation
of the odor sensor and dust sensor.
(When the fan is running automatically, it will not run at high speed.)
<Note> When the fan is running automatically, the airflow display lamps will not light up.
* In older models, when the fan is running automatically, the airflow display lamps light up,
but with this model, only the automatic green light lights up and the airflow display
lamps do not. (It is not possible to tell at what airflow speed the fan is operating.)

<Motor Protection Function>
If the fan is operated at high speed in manual operation with the front cover, pre-filter and filter
removed, the revolution speed is dropped slightly for about 1minute and 10 seconds to protect
the motor.
(If the motor is operated while the filter, etc., is removed, a large burden is placed on the motor
(only at times of high speed operation) so the motor protection function starts to work.)
