When 40° degrees or 60° degrees airflow is selected with the LOW fan speed in COOL operation, “AUTO RETURN” will appear below the temperature display. One hour later, the airflow direction returns to horizontal automatically and “AUTO RETURN” will disappear. If the airflow direction is set to horizontal during “AUTO RETURN” indication, the time counting for AUTO RETURN is cancelled.
