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 conditioneris stopped 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 aboveand the positions of the vane are as Figure 2 below. When the air conditioner is stopped using remote control,the vane will shift to close position.12.4.2 Horizontal Airflow The horizontal airflow direction louvers can be adjusted manually by hand.12.5 Timer Control There are 2 sets of ON and OFF timer available to turn the unit ON or OFF at different preset time. If more than one timer had been set, the upcoming timer will be displayed and will activate in sequence.12.5.1 ON Timer Control ON timer 1 and ON timer 2 can be set using remote control, the unit with timer set will start operate earlier thanthe setting time.This is to provide a comfortable environment when reaching the set ON time. 60 minutes before the set time, indoor (at fan speed of Lo-) and outdoor fan motor start operate for 30 seconds todetermine the indoor intake air temperature and outdoor air temperature in order to judge the operation startingtime. From the above judgment, the decided operation will start operate earlier than the set time as shown below.
