Solution
Check if the router connected to the air
conditioner has Internet access. (You can
check by connecting the smart device to
the router, then opening the website.) If
there is no access, connect the router to
the Internet, then retry the registration.
If there is a smart device that has already
been registered to the air conditioner,
unregister by using the registered smart
device. Retry the registration with the
smart device you wish to register. If you do
not own the smart device registered to the
air conditioner (lost, property of previous
owner, etc.), ask your manufacturer service
to unregister the smart device. Inform them
the MAC address of the WLAN Adapter as
written on the Wireless LAN label.
Enter the SSID literally. (Uppercase and
lowercase letters also match)
Solution
Connect the mobile device to the Internet.
Check if the router connected to the air
conditioner has Internet access. (You can

connect the router to the Internet.
Check the wireless LAN indicator lamps on
the air conditioner. If the indicator lamp is
flashing or off, refer to "Error code table
(Wireless LAN indicator)"
