The Operation of the Dust Sensor
When the dust sensor detects dust or tobacco smoke in the room, the fan will operate
automatically at low or medium speed.
When there is a lot of dust, etc., the fan will operate at medium speed, and when there is only
a little dust, etc., the fan will operate at low speed. When the air is clean, operation will stop
(The airflow lamp will not be lit.)
(automatic).
When the dust sensor detects something, the operation of the clean sign and sterilized and
electrolyzed mist (when the electrolyzed water lamp is lit) will also change in accordance with
operational airflow in accordance with the volume of particles of dust, etc., in the air.
If the sensor's detection level does not change, the fan will step down following the completion
of the operating period for each airflow speed and finally stop (automatic). During this process,
if the detection level rises, the fan will operate at the airflow speed for that level. (If the sensor's
d etection level does not change, the fan will step down in about 4 minutes.)
Even in automatic operation, the dust sensor will not operate soon after the power plug is inserted,
but will be inactive for a period of 5 seconds. After that, even while the automatic lamp is flashing,
the odor sensor will not operate, but if the dust sensor detects something, the fan will operate at
an airflow speed in accordance with the level of dust in the room.
When the fan is switched over to automatic operation, it will operate for 5 minutes at low speed
even if the air in the room is clean. At this time, the clean sign (green) will be lit.
