humidity indication
The humidier 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
40%RH to 60%RH.
• The accuracy of the humidity indication
is approximately ±10%.
• It takes some time to measure the
humidity level in the room.
Understanding the healthy
air protect alert and lock
The healthy air protect alert gives you
a timely warning when the water tank
needs relling. When the water in the
tank starts getting low, a red indicator
on the control panel starts blinking to tell
you that it is time to rell the tank (g. h).
It blinks for 30 minutes. After that, the
indicator remains on before the water
tank is relled with water.
