6614.4 Airflow Direction There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed byvertical vanes). Control of airflow direction can be automatic (angles of direction is determined by operation mode, and heatexchanger temperature) and manual (angles of direction can be adjusted using remote control).14.4.1 Vertical AirflowOperation state Upper blade Lower bladeHeating OperationAuto C area 30° 35°B area Sensor, windbreak, wind address Refer to the part of area air-conditioningNormal powerful 60° 58°A area 10° 15°Manual Manual 1 10° 15°Manual 2 15° 38°Manual 3 30° 45°Manual 4 45° 52°Manual 5 60° 60°Cooling OperationAutoSensor, windbreak, wind address Refer to the part of area air-conditioningPowerful Air-flow initial 25° 30°Air-flow stability/instability Same as cooling manual 2Normal Neuro stability 8° ~ 30° 10° ~ 35°Neuro instability 8° ~ 35° 10° ~ 40°Manual Manual 1 (Ceiling air-flow) 0° 3°Manual 2 8° 21°Manual 3 15° 38°Manual 4 32° 46°Manual 5 50° 50°Dry OperationAuto Sensor, windbreak, wind address Refer to the part of area air-conditioningNormal, powerful Ceiling air-flowManual Manual 1 0° 3°Manual 2 8° 13°Manual 3 17° 22°Manual 4 26° 31°Manual 5 35° 40°Blower operation Automatic Same as the normal neuro stability of cooling automationManual Same as cooling manualInside drying Slight openChange control Slight openStop, filter cleaning, room temperature lookout waiting Cooling position after resetLouver opening, in check mode Same as cooling manual 5
