(1)
The operating mode “Constant Airflow” is not available for RDPs. Setting the fan in one of the three Constant Airflow modes
could make it turn in an unknown and/or uncontrollable manner.
(2)
The algorithm related to the operating mode "Asynchronous Emulation" does not produce significant differences
on RDPs in comparison to the operating mode "Speed control". Therefore, its use is not recommended.
