Johnson Controls S66AA-1 Control Refrigerant Standard Connectivity: Utilizes a standard

Standard Connectivity: Utilizes a standard 9-pin harness and clearly labeled screw terminals for thermostat and power connections

usually ranging from 120V to 240V

Designed for high-demand environments

this component is designed for both local and remote flame sensing configurations where the sensor is mounted separately from the spark electrode to monitor the main burner flame

This unit provides exceptional gas flow control for systems requiring stable downstream pressure despite fluctuating inlet pressures

Johnson Controls S66AA-1 Control Refrigerant Standard Connectivity: Utilizes a standardThe Johnson Controls S66AA 1 is a professional grade electronic fan speed control designed for modulating condenser fan motors in HVACR systems. This motor controller operates on a multi tap voltage range of 120 277 Vac and accepts a 1 10 Vdc input signal or 20 30 Vac low voltage input to precisely manage head pressure. A critical field proven feature is the integrated hard start feature, which ensures the motor overcomes initial inertia by delivering
