Abstract: There is provided a method of controlling a direction of an airflow emitted from a fan assembly, the fan assembly being capable of changing the direction of the airflow emitted therefrom to any direction within a range of adjustment of the fan assembly. The method comprises receiving user inputs that select an angle of oscillation and that determine a central emission direction for the airflow emitted from the fan assembly, and controlling the emission direction of the fan assembly such that the emitted airflow oscillates through the selected angle of oscillation with the oscillation of the emitted airflow being centered at the central emission direction.
