Various Functions

Auto Restart Control

• If there is a power failure, operation will be automatically restarted when the power is resumed with previous operation mode and airflow direction. (As the operation is not stopped by remote controller.)

• If you intend not to continue the operation when the power is resumed, switch off the power supply. When you switch on the circuit breaker, the operation will be automatically restarted with previous operation mode and airflow direction.
  Note:

  1. If you do not require Auto Restart Control, please consult your sales agent.
  2. Auto Restart Control is not available when Timer or GoodSleep Timer is set.

Auto Mode
The device will automatically determine the mode of operation, Heat Mode or Cool Mode depending on the current room temperature. The selected mode of operation will change when the room temperature varies.

Heat Mode

• Use the device for heating when the outdoor temperature is under 21°C. When it is too warm (over 21°C), the heating function may not work to protect the device.

Defrosting
Defrosting will be performed about once an hour when frost forms on the heat exchange of the outdoor unit, for 5~10 minutes each time. During defrosting operation, the operation lamp blinks in cycle of 2 seconds on and 1 second off. The maximum time for defrosting is 20 minutes.
