ERROR DETECTION
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.)
