P66 Series Electronic Fan Speed Controls
Product Bulletin
Code No. LIT-125465
Issued May 2018
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
Heating, Ventilating, and Air Conditioning (HVAC)
applications. Figure 1: P66 Dual Sensor Fan Speed Control

Features Benefits
Exclusive Johnson Controls/PENN® Responds quickly to condenser pressure changes and condenser air delivery
Pressure Transducer requirements
Soft Start Capability Provides a smooth fan startup, which reduces motor-starting noise and abrupt
changes in motor speed
208-240/277/480 VAC, 60 Hz Motor Suitable for a wide range of condenser fan motor applications
Control
One or Two Pressure Transducers Applicable to single- and multi-circuit condensers. The dual-sensor P66 control
models select the higher pressure input to control the fan speeds.

1. When two P15s are used in parallel with one motor, replace both P15s with one P66BAB. Select the P66BAB with an
operating range similar to that of the P15s being replaced. When replacing a P15 or P65 with a P66, 24 VAC must be
provided. It is recommended that the P66 be used only with low heat rise ball bearing motors that are approved by the motor
manufacturer for fan speed control operation. Start voltage for P15 motors = 40%.
