Troubleshooting at the remote control LCD

REMOTE CONTROL (option)

This is possible only on the wired remote control.

Self-diagnosis

If an error occurs, the following display will be shown.

If "CO" appears in the unit number display,

there is a remote control error.

Refer to the installation instruction sheet

included with the remote control.

(“EE” will appear in the set room temperature display.)
