Breakdown Self Diagnosis Function
Self Diagnosis Function (Three
Digits Alphanumeric Code)
# Once abnormality has occurred during operation, the unit will stop its operation, and Timer LED blinks.
# Although Timer LED goes off when power supply is turned off, if the unit is operated under a breakdown condition, the LED will light up again.
# In operation after breakdown repair, the Timer LED will no more blink. The last error code (abnormality) will be stored in IC memory.
# To make a diagnosis
1. Timer LED start to blink and the unit automatically stops the operation.
2. Press the CHECK button on the remote controller continuously for 5 seconds.
3. “- -” will be displayed on the remote controller display.
Note: Display only for “- -”. (No transmitting signal, no receiving sound and no Power LED blinking.)
4. Press the “TIMER” UP or DOWN button on the remote controller. The code “H00” (no abnormality) will be displayed and signal will be transmitted to the main unit.
5. Every press of the button (up or down) will increase abnormality numbers and transmit abnormality code signal to the main unit.
6. When the latest abnormality code on the main unit and code transmitted from the remote controller are matched, power LED will light up for 30 seconds and a beep sound (continuously for 4 seconds) will be heard. If no codes are matched, power LED will light up for 0.5 seconds and no sound will be heard.
7. The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5 seconds or operation the unit for 30 seconds.
8. The LED will be off if the unit is turned off or the RESET button on the main unit is pressed.
