10-4. Self-Diagnosis by Remote Control (Check Code)

(1)If the lamps are indicated as shown B to H in Table 10-3-1, excute the self-diagnosis by the remote control.

(2)When the remote control is set to the service mode, the indoor control diagnoses the operation condition and indicate the information of the self-diagnosis on the display of the remote control with the check codes. If a fault is detected, all lamps on the indoor unit will flashes at 5Hz and it will beep for 10 seconds (Pi, Pi, Pi....). The timer lamp usually flashes (5Hz) during self-diagnosis.
