4 Using the
humidifier

Humidity indication

The humidifier is equipped with a
built-in smart humidity control sensor.
You can set the target humidity level
at 40%RH, 50%RH and 60%RH. When
the desired humidity level is reached,
the color of the humidity indicator light
is blue. When the humidity level is not
reached, the humidity indicator light is
red.
Note
•
A comfortable humidity level is from
40RH% to 60RH%.
•
The accuracy of the humidity indication
is approximately ±10%.
•
It takes some time to measure the
humidity level in the room.
•
The humidity indicator light automatically
goes on when the humidifier is switched
on.

Automatic shut-off

The automatic shut-off gives you a
timely warning when the reservoir needs
refilling. When the water in the reservoir
starts getting low, a red indicator on
the control panel starts blinking to tell
you that it is time to refill the reservoir
(fig. i). It blinks for 30 minutes. After
that, the indicator remains on before the
reservoir is refilled with water.
When the reservoir is empty and
needs to be refilled, the humidifier
automatically shuts off and a red
indicator light turns on. When you
refill the reservoir, the humidifier
automatically turns on again.
