Product Description P/N: P66AAB-25C
Description
The Johnson Controls P66AAB-25C is a pressure-actuated electronic fan speed control for condenser fans in refrigeration and air conditioning equipment. It adjusts motor voltage in response to refrigerant pressure across a 180–240 psig operating range, helping maintain condenser pressure as cooling conditions change.

Information About P66AAB-25C
The P66AAB-25C is a single-sensor model in the Johnson Controls/PENN P66 Series. Its galvanized steel enclosure houses electronic speed-control circuitry connected to a refrigerant pressure sensor through a 120-inch capillary. It is intended for single-phase, ball-bearing permanent split-capacitor motors approved by their manufacturer for solid-state speed control. Johnson Controls identifies this model as the replacement for P66AAB-18 in its published replacement guide.
Key Features:
- Pressure-responsive operation: Varies condenser fan motor voltage according to sensed refrigerant pressure.
- Defined operating range: Provides modulation across 180–240 psig.
- Single pressure input: Uses one sensing connection for the controlled refrigerant circuit.
- Extended capillary: Includes a 120-inch tube for positioning the pressure connection.
- Model-specific start voltage: Begins modulation at 10% of the applied line voltage.
- Soft start capability: Reduces abrupt changes in fan speed during startup.
- Separate control supply: Uses 24 VAC control power alongside the motor line-voltage circuit.
- Service replacement: Replaces the earlier P66AAB-18 control in compatible applications.
The P66AAB-25C delivers the reliability and precision required for pressure-responsive condenser fan regulation in compatible refrigeration and air conditioning systems.
