Johnson Controls P266BHA-100 Control

The Johnson Controls P266BHA-100 is an industrial-grade single phase condenser fan speed control designed to maintain stable head pressure in high-voltage HVACR systems. Engineered for 460/575 Vac applications, this digital electronic motor speed control provides precise modulation for Permanent Split-Capacitor (PSC) motors, effectively replacing the legacy P66 and P215 series. With a 4.0 ampere maximum output and high VAC triacs, it regulates fan speed by limiting supply voltage based on real-time refrigerant pressure. This model features three auxiliary control circuits to manage additional fixed-speed fan stages, ensuring optimized airflow across the condenser. Built into a NEMA 3R rainproof enclosure with an integral metal heat sink, it is rated for ambient temperatures from -40°F to 140°F. The P266BHA-100 utilizes ratiometric pressure transducers to eliminate capillary tube failure points and provide a 1% total error band for superior system efficiency.

• Precise Pressure Regulation: Maintains consistent head pressure by adjusting condenser fan speed in response to sensed refrigerant pressure.
• Multi-Fan Capability: Includes 3 auxiliary fan control circuits to manage fixed-speed fans alongside the primary modulated motor.
• Rugged Durability: Housed in a NEMA 3R enclosure with stand-off mounting feet, specifically designed for harsh outdoor HVACR environments.
• High-Voltage Compatibility: Specifically rated for 460/575 Vac supply power, meeting the requirements of heavy commercial refrigeration.
• Energy Efficiency: Reduces fan cycling and motor wear by matching fan speed to the actual system load.

Is the transducer included with this model?
No, the P266BHA-100 is the control unit only. It must be paired with a P266SNR series electronic pressure transducer for proper operation.

Can I use this with any single-phase motor?
This control is specifically designed for Permanent Split-Capacitor (PSC) motors approved for speed control. Using it with non-PSC motors can lead to motor damage.

How do the auxiliary circuits work?
The three auxiliary circuits act as stages that trigger fixed-speed fans as cooling demand increases beyond the capacity of the primary modulated fan.
