Johnson Controls P266BHA-3K Fan Control

The Johnson Controls P266BHA-3K Fan Control is a versatile, pressure-actuated digital 460-575 VAC solution designed to replace legacy P66 and P215 series fan speed controllers. This single-phase condenser fan speed control kit handles demanding 440-575V applications with a robust 4-amp rating and includes a P266SNR-2C pressure transducer capable of monitoring 0 to 754 psi (0 to 52 bar). Engineered for PSC motor speed control, the unit utilizes dual high-voltage triacs to regulate supply voltage in response to refrigerant pressure, ensuring stable head pressure and extending motor life in low-ambient conditions. Its NEMA 3R rainproof enclosure features an integral metal heat sink, making it a rugged choice for commercial refrigeration and rooftop HVAC units. With support for up to three auxiliary fan circuits, this controller offers technical flexibility for complex multi-fan staging while maintaining high operational efficiency across 50/60 Hz systems.

• Direct Replacement: Seamlessly replaces older Johnson Controls P66 and P215 models with modernized digital precision.
• All-Weather Reliability: NEMA 3R enclosure with vertical heat sink fins ensures performance in extreme outdoor environments.
• Wide Pressure Range: Included 0-754 psi transducer and 6.6-foot cable allow for versatile high-pressure monitoring.
• Multi-Fan Capability: Built-in logic for auxiliary fan control allows for staging of up to three additional fixed-speed fans.
• Energy Efficiency: Maintains optimal head pressure, reducing overall system energy consumption and mechanical wear on HVACR condenser fans.

What is the maximum amperage for the P266BHA-3K?
This specific 460/575 VAC model is rated for a maximum output of 4 amperes. Always verify the total Full Load Amps (FLA) of the connected motors to ensure compliance.

Can I use this with any motor?
The P266 series is specifically designed for single-phase PSC motors approved for speed control. Usage with non-compatible motors can lead to equipment failure.

Is the transducer included in this kit?
Yes, the P266BHA-3K kit includes one P266SNR-2C pressure transducer (0-754 psi) and one 2-meter (6.6 ft) connection cable.
