The error code "CL" on a Koryo air conditioner typically indicates that the Child Lock feature is activated. The Child Lock is a safety feature designed to prevent accidental or unauthorized operation of the air conditioner, especially in households with young children.
When the Child Lock is enabled, the air conditioner's control panel and buttons become locked, and you won't be able to change settings or turn the unit on/off without disabling the lock first.
To remove the "CL" error code and disable the Child Lock on your Koryo air conditioner, you can follow these general steps (as the specific procedure may vary depending on the model):
Look for the Child Lock button on the air conditioner's control panel. It is usually labeled "CL" or "Child Lock."
Press and hold the Child Lock button for a few seconds until the "CL" indicator or the lock symbol disappears from the display.
Once the Child Lock is deactivated, the air conditioner's control panel should be fully functional again, and you can use the buttons to adjust settings and operate the unit as usual.
If the above steps don't work or you cannot find the Child Lock button, refer to your Koryo air conditioner's user manual for specific instructions on how to disable the Child Lock feature. If you no longer have the manual, you can try looking it up online by searching for your air conditioner's model number along with "user manual" or contacting Koryo customer support for assistance.
