During cooling operation, and outdoor ambient temperature is below 8°C, outdoor fan speed will be controlled
according to outdoor piping temperature as following:
OD Pipe Temperature
A 26°C
B 33°C
During above condition, when indoor heat exchanger temperature is below 5°C, the outdoor fan will stop
according to outdoor piping temperature as following:
14.4 Airflow Direction
There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by
vertical vanes).
Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat
exchanger temperature and intake air temperature) and manual (angles of direction can be adjusted using
remote control).
