you should run your circulating fan in the room at all times, your ventilation fans such as intake or exhuast may not be needed or not needed as much you would need to monitor your temp and humidity to see if the ventilation fans are needed to keep temp within a normal range and humidity under 70 percent.
if your humidity is running very high 60 or better would probably suggest leaving atleast one ventilation fan on, or installing a controller that will turn on and off fans based on temp and humidity.
