Operation

Auto restarting operation

Forced operation

• When the power is restarted after a sudden power failure while in appliance operation, the mode before the

power failure is kept on the memory and the appliance automatically operates in the mode on the memory.

• Operation mode that is kept on the memory

- State of operation ON/OFF
- Operation mode/setting temp./selected airflow speed
- Sleep timer mode/remaining time of sleep timer
- Chaos Swing

• To operate the appliance by force in case that the remote control is lost, the forced operation selection switch

is on the main unit of the appliance to operate the appliance in the standard conditions.

• The operation condition is set according to the outdoor temp. and intake air temperature as follows.

❈

The unit select before operating mode in 3 hours.

DC Peak Current Error by a fault signal of IPM

• If the operating current of IPM reaches 35A ±3A, the compressor stop instantly.
• If DC PEAK occurs 5 times within 1 hour, the appliance turns off and display ERROR CODE 21.

■

DC Peak Current Error by the compressor lock

• If the DC LINK voltage below DC 140V occurs 5 times within 1 hour while the compressor is operating, the

appliance turns off and display ERROR CODE 21.

■

DC Peak Current Error by the Outdoor Fan Lock

• If it’s 5 times within 1 hour in case of the temperature of outdoor pipe TH is over 65°C while the compressor is

operating, the appliance turns off and display ERROR CODE 21.
