CONTROL 400VAC 50/60HZ; CONTROL 400VAC 50/60HZ NO

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 HVAC/R 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 include:

• 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.
