Description
The Johnson Controls P66AAB-39C is a PENN P66 Series Electronic Fan Speed Control. Per the manufacturer, the P66 Series Electronic Fan Speed Controls "are refrigerant pressure actuated, electronic motor-speed controllers. The P66 controls are designed for use with single-phase permanent split-capacitor motors that are approved by the motor manufacturer for speed control applications. The P66 controls provide condenser pressure control by directly sensing condenser refrigerant pressure and automatically adjusting the condenser fan motor speed according to the sensed pressure."
The P66 provides an alternative to fan cycling control in many small and medium size refrigeration and HVAC applications, and can replace On/Off fan cycling controls, multiple speed motors, condenser flood-back systems, temperature fan-speed controls and modulating louver systems. Between 0 psig and the low end of the operating range the motor receives 0 to 5 volts; at the low end of the range the control applies its model-specific start voltage; within the operating range motor voltage varies directly with system pressure up to 90% of line voltage; and a further pressure rise of 20 to 30 psi above the range increases motor voltage to 97% of the applied voltage. The exclusive Johnson Controls/PENN pressure transducer responds quickly to condenser pressure changes and air delivery requirements, and soft start capability gives a smooth fan startup that reduces motor-starting noise and abrupt changes in motor speed.

Typical applications include commercial refrigeration, commercial air conditioning and computer room air conditioning. Use only single-phase permanent split-capacitor, ball-bearing motors approved by the manufacturer for speed control applications; sleeve-bearing motors are not acceptable, and using a non-PSC motor may damage the motor and other property. Use this control only as an operating control - where failure or malfunction could lead to personal injury or property damage, incorporate additional supervisory, alarm, safety or limit devices into the control system. Do not make field repairs.. Johnson Controls. Johnson Controls. P66AAB-39C.
