Johnson Controls P266BDA-100 Fan Speed Control

The Johnson Controls P266BDA-100 is a high-performance single-phase condenser fan speed control designed specifically for PSC (Permanent Split-Capacitor) motors. Operating within a 460/575V 50/60 Hz range, this pressure-actuated controller replaces legacy P66 and P215 series units, offering superior energy efficiency and motor longevity. It features a 4A current rating and comes equipped with three auxiliary fan control circuits, allowing for precise staging of fixed-speed fans in multi-circuit condenser applications. The NEMA 3R rainproof enclosure with an integral metal heat sink ensures reliable operation in demanding outdoor HVACR environments, maintaining stable head pressure by modulating fan speed based on real-time refrigerant pressure. This digital electronic control is essential for contractors managing commercial refrigeration or computer room air conditioning systems where ambient temperature variations require accurate airflow regulation.

• Broad Voltage Range: Engineered for heavy-duty 460V and 575V VAC systems without the need for additional step-down transformers.
• Advanced Staging: Includes three auxiliary contacts to manage additional fan stages, optimizing total system performance.
• Rugged Durability: Housed in a NEMA 3R / IP54 case that resists vibration and environmental shock.
• Direct Integration: Seamlessly interfaces with P266 series electronic pressure transducers for a 1% total error band in pressure sensing.
• Extended Motor Life: Soft-start capabilities and precision modulation reduce thermal stress on motor windings.

What motor types are compatible with the P266BDA-100?
This controller is strictly for use with approved single-phase Permanent Split-Capacitor (PSC) motors commonly found in refrigeration condensers. It is not designed for shaded pole or three-phase motors.

Can I use this to replace an older P66 control?
Yes, the P266 series is the direct technical successor to the Johnson Controls P66 and P215 series, providing a more compact and energy-efficient footprint with improved digital accuracy.

What is the maximum amperage for this specific model?
The P266BDA-100 is rated for a maximum output of 4 Amperes. Always verify the total FLAs of all modulated motors to ensure you do not exceed this limit.
