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

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 airflow
speed from skipping frequently, it must be kept under each mode for over 30 seconds, and then it can be
changed to another mode (when refrigerating, the time is changed to 15 seconds).
5.2.2.1 The outdoor fan control when refrigerating or dehumidifying
After the compressor is started for 5 seconds, the outdoor fan is started at the medium speed at first, after 30
seconds, it begins to control the airflow speed according to the temperature conditions of the outdoor
environment.

5.2.3 The control of the outdoor electronic expansion valve EEV
In cooling mode, the EEV opening range is 90~480 steps. The EEV opening is 5 steps when unit is off.
In heating mode, the EEV opening range is 60~480 steps. The EEV opening is 45 steps when unit is off.
After outdoor unit is off, the EEV opening keep the current on for 5s, then open the EEV completely for 2
minutes, then become 5 steps (cooling) or 45 steps (heating).
The EEV opening will increase if SH(superheat degree) >0 while decrease if SH<0
