Description
The Johnson Controls P266ABA-3K Fan Speed Control is an equipment that is used with fans that are found in most HVAC systems and is mainly used in controlling the speed of the fans. Its operation involves the transformation of a pressure signal that may be between 0 and 755 PSI into an electrical signal that regulates the motor of the fan. This in turn permits fine optimization of airflow with the exact needs of the system thus improving performance and efficiency. Used with variable air volume systems, the P266ABA-3K assists in maintaining pressure across the ducting system.
