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.

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 maker service to
unregister the smart device. Notify 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 W-LAN LED indicators on the
air conditioner. If the W-LAN LED lamp is
flashing or off, refer to "Error code table
