Compressor overcurrent interruption
*1 If the beeper does not sound again after the initial
2 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 3 times continuously “beep, beep, beep (0.4 + 0.4 + 0.4 sec.)” after the initial 2 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 display in the LCD.
