Johnson Controls P266ABA-100 Control

The Johnson Controls P266ABA-100 is a specialized single-phase condenser fan speed control designed to optimize head pressure management in HVACR refrigeration systems. Engineered for 208/240 VAC applications, this unit provides precise modulation for permanent split capacitor (PSC) motors, effectively replacing legacy P66 and P215 series controls with superior digital accuracy. Rated for a maximum output of 8 amperes, the P266ABA-100 utilizes three high VAC triacs to ensure smooth voltage transitions and stable motor operation even in demanding environments. This model is particularly robust for contractors managing multi-stage setups, as it includes three available auxiliary fan control circuits to cycle additional fixed-speed fans. Housed in a NEMA 3R rainproof enclosure, it maintains critical condenser pressure control by responding to real-time transducer data, preventing low-ambient cooling issues and extending the service life of your fleet's compressor and motor components.

• Enhanced Head Pressure Regulation: Maintains consistent refrigerant pressure by modulating fan speed, vital for low-ambient cooling operations.
• Scalable Fan Management: Direct control of the primary motor plus three auxiliary fan stages for complex condenser configurations.
• Industrial-Grade Durability: The NEMA 3R (IP54) aluminum and polycarbonate housing protects internal electronics from harsh outdoor weather.
• Triac-Based Performance: Features three high VAC triacs for efficient power handling and reduced electrical noise during motor speed adjustment.
• Direct Retrofit Capability: Designed specifically as a modern upgrade for older P66 and P215 series fan speed controllers.

Is the pressure transducer included with the P266ABA-100?
No, the P266ABA-100 is the control unit only. For a complete installation, you must pair this with a compatible P266SNR series electronic pressure transducer.

Can I use this control with any single-phase motor?
This control is specifically designed for Permanent Split Capacitor (PSC) motors that are approved by the manufacturer for speed control. It should not be used with shaded pole or other motor types not intended for modulation.

What is the maximum current load this unit can handle?
The P266ABA-100 is rated for a maximum output of 8 amperes. If your total motor load (including parallel motors) exceeds 80% of this rating, verify the startup inductance of your specific motor configuration to ensure stable performance.
