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).
