Indoor Fan Curve
This section presents the performance curve for the indoor fan, illustrating the relationship between Airflow (l/s) on the x-axis and External Static Pressure (Pa) on the y-axis. The graph shows multiple lines representing different current draws (e.g., 1.55A, 2.81A, 4.39A, 5.31A) at various airflow and pressure points. The application range for airflow is indicated, noting that airflow can be lower during ESP Auto Fan Mode.
