The P66 series electronic fan speed controls are refrigerant pressure actuated, electronic motor-speed controllers. The P66 controls are designed for use with 1-PH permanent split-capacitor motors that are approved by the motor manufacturer for speed control applications. The P66 controls provide condenser pressure control by directly sensing condenser refrigerant pressure and automatically adjusting the condenser fan motor speed according to the sensed pressure. The P66 provides an alternative to fan cycling control in many small and medium size refrigeration and heating, ventilating, and air conditioning (HVAC) applications.
