6514.4 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, heatexchanger temperature and intake air temperature) and manual (angles of direction can be adjusted usingremote control).14.4.1 Vertical AirflowOperation Up-and-down inner vaneStep 1 Step 2 Step 3 Step 4 Step 5CoolingAuto Usual (Ventilation) [110] degrees – [65] degreesControl with dew [110] degrees – [65] degreesManual Usual (Ventilation) [110°] 110° 90° 70° [65°]Control with dew [110°] 110° 90° 70° [65°]DryAuto Usual [110] degrees – [65] degreesControl with dew [110] degrees – [65] degreesManual Usual [110°] 110° 90° 70° [65°]Control with dew [110°] 110° 90° 70° [65°]HeatingManual [110°] 110° 100° 90° [80°]AutoA zone [110°]B zone [90°]C zone [110°]Operation Up-and-down outer vaneStep 1 Step 2 Step 3 Step 4 Step 5CoolingAuto Usual (Ventilation) [55] degrees – [85] degreesControl with dew [55] degrees – [85] degreesManual Usual (Ventilation) [55°] 62° 72° 83° [85°]Control with dew [55°] 62° 72° 83° [85°]DryAuto Usual [55] degrees – [85] degreesControl with dew [55] degrees – [85] degreesManual Usual [55°] [55°] [55°] [55°] [55°]Control with dew [55°] [55°] [55°] [55°] [55°]HeatingManual [55°] 62° 72° 83° [90°]AutoA zone [55°]B zone [83°]C zone [62°]1. Automatic vertical airflow direction can be set using remote control; the vane swings up and down within theangles as stated above. For heating mode operation, the angle of the vane depends on the indoor heatexchanger temperature as Figure 1 below. It does not swing during fan motor stop. When the air conditioner isstopped using remote control, the vane will shift to close position.2. Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated above andthe positions of the vane are as Figure 2 below. When the air conditioner is stopped using remote control, thevane will shift to close position.58°C50°CIndoor HeatExchanger Temperature37°C30°CCAFigure 1B
