The calculation of the actual output frequency: when there is no healthy airflow: F =F-ED-*×P×K
When the healthy airflow has been set: F =F-ED-*×P×K airflow speed ×K healthy airflow
When refrigerating, it is needed to satisfy
When heating, it is needed to satisfy
5.2.2: The outdoor fan control (exchange fan)
When the fan is changed among every airflow speed (including stop blowing), in order to avoid the
