P266xxx-x
P266 Series Single-Phase Condenser Fan Speed Control
Code No. LIT-1900595
Issued August 27, 2010
P266 Series Single-Phase
Condenser Fan Speed Control
Description
The P266 Series Single-Phase Condenser
Fan Speed Control is a cost-effective,
weather-resistant, durable motor speed
control. 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 power to the main
and auxiliary windings, and connect a
low-speed capacitor to increase efficiency at
low-speed operation.
Refer to the P266 Series Single-Phase
Condenser Fan Speed Control Product
Bulletin (LIT-12011534) for important product
application information.

Application
The P266 Series Single-Phase Condenser
Fan Speed Control, in conjunction with a P266
Series Electronic Pressure Transducer, is a
pressure-actuated, digital electronic motor
speed control designed for approved single-
phase, PSC motors used in a wide variety of
Heating, Ventilation, Air Conditioning, and
Refrigeration (HVACR) applications.
The P266 Series Fan Speed Control regulates
supply voltage to the fan motor in response to
the condenser refrigerant pressure and
maintains the appropriate fan speed (air
movement) through the condenser regardless
of the ambient temperature or air delivery
variations.
The P266 Series control is housed in a NEMA
3R (IP54) rainproof enclosure for outdoor
applications.
The P266 Series control is an energy efficient
and effective alternative to On/Off fan-cycling
controls, multiple-speed motors, temperature
fan-speed controls, modulating air-damper
systems, condenser flood-back systems, and
other condenser pressure control methods.
P266 Series Fan Speed Control applications
in
clude:
• computer room air conditioning
• commercial refrigeration
• commercial air conditioning
Repair Information
If a P266 Series Single-Phase Condenser Fan
Speed Control fails to operate within its
specifications, replace the unit. For a
replacement P266 Series control, contact the
nearest Johnson Controls representative.
