Remarks: the above are not only the maximum frequency limitations of the complete appliance which
are affected by the environment, but also the maximum ability limitation of the system. When the
starting ability is not the maximum, its maximum frequency limitation is calculated by the following
equations:
The frequency limitation which is affected by the temperature and under the condition of actual ability
the actural running system ability*the maximum frequency which is limited by the temperature and
under the condition of maximum ability/the maximum designing ability of the system
T=
Ti*Pi / Pi ( Ti=|Tst_i-Tnh_i the indoor environment temperature| ;Pi i the ability of the
indoor unit)

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 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
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,
