Faults with indication
A fault on the appliance can also be indicated by the sequential flashing
of the following lights:
• ON indicator
K
(green)
• Timer lamp
(orange)
• WLAN lamp
(green)
The number of flashing signs specify the number of the fault codes.
When the fault
23 – 4
occurs for example, the ON indicator
K
(green)
flashes twice, then the timer light
(orange) flashes 3 times and the
WLAN light
(green) flashes 4 times.
Error code structure
The error code consists of a main code and a sub code:

▶ Press
.
or
/
on the

button to change the number step by
step between 00 and 31.
– The buzzer makes a long beep if the displayed main code number
belongs to an active error (23 in the example above).
– Otherwise the buzzer makes a short beep.
▶ Press the
Fan
button once.
The remote control displays – 0.
▶ Press
.
or
/
on the

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
warm air
The unit is preheating or de-icing.
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
outlet
In cooling mode, this is caused by the
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.
The outdoor unit does
not stop
After stopping operation, the outdoor unit will
rotate its fan for about 1 minute to cool down
the unit.
Odor emitted from the
plasmacluster air
outlet
This is the smell of ozone generated from the
plasmacluster ion generator. The ozone
concentration is very small, posing no adverse
effect on your health. The ozone discharged
into the air rapidly decomposes, and its
density in the room will not increase.
Fault
Remedy
If the unit fails to
operate
Check if the circuit breaker has tripped or the
fuse has blown.
If the unit fails to heat
(or cool) the room
effectively
• Check the filters for dirt and clean them.
• Check the outdoor unit to make sure
nothing is blocking the air inlet or outlet.
• Check if the temperature is properly set.
• Make sure windows and doors are closed
tightly.
If the unit fails to
receive the remote
control signal
• Check whether the remote control
batteries have become old and weak.
• Try to send the signal with the remote
control pointed directly towards the unit’s
signal receiver window.
• Check whether the remote control
batteries are inserted properly.
Connection cannot be
established to the app.
• Check the WLAN signal strength. If
necessary, bring the router closer to the
indoor unit or use a WLAN repeater.
• Check the correct entry of the login data.
