Temperature Pressure Controls
TheFSXFanSpeedControlcontrolstheheadpressureinair–
cooled condensers by reducing the fan speed to maintain head
pressure as the outside temperatures/condenser pressure drops. As
the motor speed drops under lower ambient/load condition fan noise
is also reduced.
The FSX is designed for use with permanent split capacitor and
shaded pole fan motors, approved for use by motor/equipment
manufacturersforvariablevoltage,phaseangle(triac)speed
control.
