Description
The Johnson Controls P266ABA-100 is a single-phase condenser fan speed control engineered for reliable, precise fan speed regulation in commercial and light-industrial HVAC condensing applications. Designed to operate on 208/240 Vac single-phase power, this controller delivers smooth, stepless fan speed modulation to maintain optimal condenser performance across varying ambient conditions — helping to protect compressors, reduce energy consumption, and extend system life.
Key Features
- Single-phase condenser fan speed control for 208/240 Vac systems
- Maximum output rating of 8 amperes for robust motor load handling
- 3 high-VAC triacs for reliable solid-state switching and speed control
- 3 available auxiliary fan control circuits for multi-fan or staged fan configurations
- Stepless speed modulation helps maintain consistent head pressure and system efficiency
- Solid-state design minimizes mechanical wear and reduces maintenance requirements
- Suitable for commercial refrigeration and air conditioning condensing units

Application
The P266ABA-100 is ideal for HVAC technicians and contractors managing head pressure control in split systems, rooftop units, and commercial refrigeration condensers. By modulating fan speed in response to system demand, it helps prevent nuisance high-pressure lockouts during cold ambient conditions and reduces unnecessary energy use during mild weather — a critical advantage for year-round system reliability.
