12.2. SELF DIAGNOSIS DISPLAY
The diagnostic display can be seen on the receiver of the Front Grille.
∙ When an abnormality occurs, the unit automatically stops, and the TIMER LED blinks to indicate a malfunction. At the same
time, the type of abnormality will be indicated on the receiver as shown in the diagram below. Providing this information reduces
the time spent in diagnosing procedures.
∙ The diagnostic display vanishes when the power is turned off.
∙ When power is re-supplied and the Diagnostic Button on the Remote Control is pressed, the type of the previous abnormality
and the protection control works will be displayed on the receiver for approximately 10 seconds.
∙
By starting cooling operation using TEST RUN button and press the Diagnostic Button at the remote control, the previous
abnormalities are deleted.
∙ Depending on the type of abnormality, you may be able to override the abnormality and use temporary operation (for
abnormalities indicated by “
●
” mark in the table below).
Use the remote control to select cooling or heating operation mode and press OFF/ON button. At this moment, four short beeps
"bip.bip.bip.bip" will sound and TIMER LED will blink.
