Many controllers have a parameter named FST
Fan Stop temperature this parameter stops the
fan if the temperature in evaporator coil is over
the FST setting .

My question is how importan is this , i understand that is better to start the fans when the evaporator
has low temperature and stop fans when is hot but
i am worry about the ice. Maybe you get ice when you are waiting FST Temperarure.

Do you use this parameter ? It is important ?
