Quantem® Fan Speed Controls modulate fan speed according to temperature change. The fan slows to idle speed when the temperature drops below the adjustable set point and increases to maximum speed as the temperature rises from the set point to 6°F above the set point.

The controller has a variable set point of 35° F to 95° F and a variable idle of 20% to 75% full speed. The modulating bandwidth is 6° F.
