Faults

ECO mode. When movement is once again detected in the room, ECO
mode is switched off and the air conditioning system resumes
operation with the original setting.
• Function with increased activity: if the detected activity level
increases, the set temperature falls and the fan speed is increased. If
automatic vertical Swing mode is set, the airflow direction will be set
obliquely downward.
If the movement sensor fails to detect a person, this could be caused by
the following:
• There is no movement for long periods of time (for example a person
sleeping, little baby, unable to move because of injury or illness).
• Only a small area of skin is exposed (for example being covered with
a quilt, wearing thick clothes, pointing the back to the air
conditioner).
• Movements are concealed by furniture.
• The temperature difference between the room and the person's body
is small (room temperature above 30 °C.)
If the movement sensor incorrectly detects one or more persons, this
could be caused by the following:
• There are small animals such as cats and dogs moving around.
• There is too much sunshine or warm wind entering the room.
• There is an object with high temperature in the room such as a heater.
• The room temperature changes a lot in a short time.

3.11.7 Changing the brightness of the lamps

When the lamps on the unit are too bright:
▶ During operation, press the Display button.
The plasmacluster lamp on the unit turns off.
The other lamps become dark.
To light up the lamps:
▶ Press the Display button again.

3.11.8 Auxiliary mode

Use this mode when the remote control is not available.
To turn on:
▶ Press the ON/OFF button ( Fig. 1, [5]).
The ON indicator K lights up and the appliance starts in automatic
mode. Fan speed and temperature are set to auto mode.
To turn off:
▶ Press the ON/OFF button again.
The ON indicator K turns off.

Condensation may form at the air outlet if the humidity is higher than
80 % and the appliance operates continuously in Cooling mode. To
prevent this, open the vertical ventilation flaps as wide as possible
(vertical relative to the ground) and set a high fan output.
When power failure occurs
This air conditioner has a memory function to store settings when a
power failure occurs.
After power recovery, the unit will automatically restart in the same
settings, which were active before the power failure, except for timer
settings.
If the timers were set before a power failure, they will need to be set
again.
Preheating function
In heating mode the indoor fan may not start for 2 to 5 minutes after the
unit is turned on, to prevent cold air from blowing out of the unit.
De-icing function
When ice forms on the heat exchanger of the outdoor unit during heating
mode, an automatic de-icer provides heat for about 5 to 10 minutes to
remove the ice. During de-icing, the inside and outside fans stop
operating.
After de-icing is completed, the unit automatically resumes operation in
heating mode.
Heating efficiency
The outside air temperature greatly affects the heating efficiency. If the
heating efficiency is reduced due to low outside temperatures, use an
additional heater.
It takes time to warm up and heat the entire room because of the forced
air circulation system.

Perceived faults

The following conditions do not denote equipment malfunctions.
Perceived fault Cause/Description
Unit does not operate The unit can stop operating for up to 3 minutes
to protect itself.
The unit will not operate if it is turned on
immediately after it was turned off. The unit
will not operate immediately after the
operation mode is changed.
Unit does not send out The unit is preheating or de-icing.
warm air
Odors Carpet and furniture odors that entered into
the unit may be sent out from the unit.
Cracking noise This sound is generated by the friction of the
unit expanding or contracting due to change of
temperature.
A low buzzing noise This is a sound of the unit generating
plasmacluster ions.
Swishing noise The soft, swishing noise is the sound of the
refrigerant flowing inside the unit.
Mist seen at indoor air In cooling mode, this is caused by the
outlet difference between the room temperature and
the discharged air temperature.
Water vapour In heating mode, water vapour may flow out of
the outdoor unit during de-icing.
