[8] TROUBLESHOOTING GUIDE

1. Self-Diagnosis Function and Display Mode

To call out the content of the self-diagnosis memory, hold down the emergency operation button for more than 5 seconds when the indoor unit is not

operating.

• The number of indications displayed by the LEDs on the outdoor unit differs from that for the 2001 cooling unit models (for detailed display of mal-

function information).

The display of malfunction No. differs from that of the 2001 cooling unit models. To show detailed malfunction information, two types of numbers

flash alternately. (example: "21" ←→ "-0")

1) The content of the self-diagnosis memory can be called out and displayed on the seven-segment display section on the indoor unit. (The error

data cannot be called out for display by the LED on the outdoor unit.)

2) If the power cord is unplugged from the AC outlet or the circuit breaker is turned off, the self-diagnosis memory loses the stored data.

a) The self-diagnosis display function of the indoor unit indicates the content of diagnosis by showing the error main category (number) and the

error sub-category (-number) alternately in 1-second intervals on the seven-segment display section of the indoor unit.

Example of self-diagnosis display on indoor unit: Compressor high-temperature error

b) The self-diagnosis display function of the outdoor unit indicates the error information by flashing LED1 on the outdoor unit according to the con-

tent of self-diagnosis.

The self-diagnosis display function of the outdoor unit is active only for about 3 to 10 minutes after self-diagnosis is performed during operation,

and the display returns to normal condition after this display period.

The content of self-diagnosis cannot be called out by the self-diagnosis display function of the outdoor unit.

Example of self-diagnosis display on outdoor unit: Compressor high-temperature error

c) The content of diagnosis is transferred to the indoor unit via serial communication, but it does not trigger a complete shutdown operation.

: Flashes in 2-sec intervals (normal), : On, : Off, : Flashes 3 times in 0.2-sec intervals (When LED1 on the outdoor unit flashes in 2-sec

intervals, the outdoor unit is in normal condition.)
