9. Test run
[Output pattern B] Errors detected by unit other than indoor unit (outdoor unit, etc.)
*1 If the beeper does not sound again after the initial two beeps to confirm the self-check start signal was received and the OPERATION INDICATOR lamp does
not come on, there are no error records.
*2 If the beeper sounds three times continuously “beep, beep, beep (0.4 + 0.4 + 0.4 sec.)” after the initial two beeps to confirm the self-check start signal was
received, the specified refrigerant address is incorrect.
• On wireless remote controller
The continuous buzzer sounds from receiving section of indoor unit.
Blink of operation lamp
• On wired remote controller
Check code displayed on the LCD.
• If the unit cannot be operated properly after the above test run has been performed, refer to the following table to remove the cause.
On the wireless remote controller with conditions above, following phenomena takes place.
• No signals from the remote controller are accepted.
• OPE lamp is blinking.
• The buzzer makes a short ping sound.
Note:
Operation is not possible for about 30 seconds after cancellation of function selection. (Correct operation)
For description of each LED (LED1, 2, 3) provided on the indoor controller, refer to the following table.
9.3. AUTO RESTART FUNCTION
Indoor controller board
This model is equipped with the AUTO RESTART FUNCTION.
When the indoor unit is controlled with the remote controller, the operation mode, set temperature, and the fan speed are memorized by the indoor controller board. The auto
restart function sets to work the moment the power has restored after power failure, then, the unit will restart automatically.
Set the AUTO RESTART FUNCTION using the remote controller. (Mode no.01)
Wireless remote controller

Symptom
Cause
Wired remote controller
LED 1, 2 (PCB in outdoor unit)
PLEASE WAIT
For about 2 minutes
following power-on
After LED 1, 2 are lighted, LED 2 is turned off,
then only LED 1 is lighted. (Correct operation)

(Correct operation)
PLEASE WAIT
Error code
After about 2 minutes
has expired following
power-on
Only LED 1 is lighted.
LED 1, 2 blink.
• Connector for the outdoor unit’s protection device is not
connected.
• Reverse or open phase wiring for the outdoor unit’s power
terminal block (L1, L2, L3)
Display messages do not appear
even when operation switch is
turned ON (operation lamp does
not light up).
Only LED 1 is lighted.
LED 1, 2 blinks twice,
LED 2 blinks once.

(incorrect polarity of S1, S2, S3)
• Remote controller wire short
LED 1 (power for microcomputer)
Indicates whether control power is supplied. Make sure that this LED is always lit.
LED 2 (power for remote controller)
Indicates whether power is supplied to the remote controller. This LED lights only in the case of the
indoor unit which is connected to the outdoor unit refrigerant address “0”.
LED 3 (communication between indoor and outdoor units)
Indicates state of communication between the indoor and outdoor units. Make sure that this LED is
