Remedy
• Only 3 icons are displayed

the Speed down and Rotation
buttons on the control panel at
the same time for 3 seconds.
• Displayed when UV does not
operate normally. (Check if the
filter and air intake (cover) are
installed in the correct position.)
• Temperature and humidity values
may fluctuate continuously in an
environment where outside air is
introduced.
• Temperature and humidity may
vary depending on the surrounding
environment such as doorways,
windows, and ventilation holes.
• Temperature and humidity may
appear differently depending on air
circulation in the same room. Also,
the temperature and humidity may
be different from other products
and thermo- hygrometers.
• Depending on the indoor
environment, the temperature
and humidity values may remain
unchanged for a long time.
• Unplug the power cord from the outlet
and plug it in again after a minute.
• If you determine that the temperature
and humidity values are abnormal, try
Smart Diagnosis.
• Clean the filter or replace it
with a new one.
• After heating operation, the
product must be turned off
after removing residual heat.
Turn off the product after
