8.11 Circulation Airflow (FXFSQ only)
Unevenness of room temperature and the startup time are improved by repeating 2-direction
horizontal blow-off and swing alternately.
8.11.1 Initiation Conditions of Circulation Operation
When operation starts (in the startup state)
Circulation airflow operation is performed.
During normal operation
The unit automatically determines operation based on the room temperature condition and time
to switch circulation airflow operation and the normal auto airflow rate and direction (eco full
automatic control).
