P266 Series Single-Phase Condenser Fan Speed Controls
Product Bulletin
P266xxA-xx Code No. LIT-12011534
Issued May 2018
The P266 Series Single-Phase Condenser Fan Speed
Controls are cost-effective, weather-resistant, durable
motor speed controls. The P266 Series Controls are
designed for approved single-phase, Permanent
Split-Capacitor (PSC) motors commonly used in a wide
variety of refrigeration and air conditioning condenser
fan applications.
The P266 Series Controls are designed to replace the
Johnson Controls® P66 Series and P215 Series Fan
Speed Controls, providing additional features and
flexibility, greater energy efficiency, and longer motor
life in a compact, rugged, weather-resistant package.
P266 Series Controls are available for 208 through
575 VAC 50/60 Hz range applications. P266 Series
Controls have current ratings from 4 to 12 A,
depending on the voltage and model.
Some P266 Series Controls provide optional control of
up to three auxiliary (fixed-speed) fans or fan stages. In
addition, some models provide two additional
high-voltage triacs that allow you to split the source Figure 1: P266 Series Single-Phase

a low-speed capacitor to increase efficiency at
low-speed operation.

Remote-Mount Pressure Transducers extreme environmental conditions; eliminate capillary tube breaks and
greatly reduce refrigerant loss potential; provide 1% total error band; and
are applicable to single and multi-circuit condenser applications.
Available in 208/240 VAC (8 or 12 A), Provides efficient PSC motor speed control for a wide range of
380/460 VAC (4 A), or 460/575 VAC (4 A) condenser fan applications.
Wide, Adjustable Pressure Throttling Range Enables application flexibility and allows you to tune condenser
operation to specific pressure ranges and ambient environments.
Optional Auxiliary Fan Control Provides control of up to three fixed-speed fans or fan stages in
conjunction with the speed controlled fan or fan stage.
Optional Low-Speed Capacitor Mode Enables cooler, quieter, and more efficient fan motor operation at low
speeds.
