16.2. Breakdown Self Diagnosis Function

16.2.1.

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”   or   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
operating 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.

•

To display memorized error (Protective operation)
status

1. Turn power on.
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”   or   button on the remote

controller. The code “H00” (no abnormality) will be
displayed and signal will be transmitted to the main unit.
The power LED lights up. If no abnormality is stored in the
memory, three beeps sound will be heard.

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
operating the unit for 30 seconds.

8. The same diagnosis can be repeated by turning power on

again.

•

To clear memorized error (Protective operation) status
after repair:

1. Turn power on (in standby condition).
2. Press the AUTO button for 5 seconds (A beep receiving

sound) on the main unit to operate the unit at Forced
Cooling Operation modes.

3. Press the CHECK button on the remote controller for

about 1 second with a pointed object to transmit signal to
main unit. A beep sound is heard from main unit and the
data is cleared.

•

Temporary Operation (Depending on breakdown status)

1. Press the AUTO button (A beep receiving sound) on the

main unit to operate the unit. (Remote control will become
possible.)

2. The unit can temporarily be used until repaired.
