Problem
Analysis of the problem
The air conditioning unit is not working.
•
Has a power outage occurred?
•
Has the circuit breaker been turned off or has
a fuse burned out?
•
Are there any obstacles or equipment
blocking the signal transmitted by the remote
control?
The remote control is not working and no
information is shown on the display.
•
Check that the batteries are not flat.
•
Check that the batteries are inserted
correctly.
The air conditioning device will not start
immediately after the I/O button on the remote
control is pressed.
•
This is a form of protection of the air
conditioner.
It is necessary to wait for about 3 minutes.
At the end operation the fan will stop
completely.
•
Turn the air conditioning device on and then
off again.
The cooling or heating (only for models with
a heat pump) performance is insufficient.
•
Have you set the correct temperature?
•
Are the filters clean?
•
Is the air inlet and outlet on the indoor and
outdoor unit blocked?
•
Are you using the SLEEP mode during the
day?
•
Is the fan in the indoor unit set to a slow
speed mode?
•
Have you closed doors and windows?
Hot air will not start flowing out of the air
conditioning device immediately after the HEAT
mode is set (only for models with a heat pump).
•
Please wait a few minutes.
A power outage occurred. After power is
renewed the air conditioner is automatically set
to the same mode in which it was before the
power outage occurred.
•
This is a so-called automatic restart function.
