Johnson Controls P266EFA-1K Fan Speed Control 0-508 PSI 208-240V 12A

The Johnson Controls P266EFA-1K Fan Speed Control is basically an advanced regulatory device that controls airflow. Being small in size it allows effective operation in modifying the fan speed according to the prevailing circumstance. It works with most standard HVAC fan motors, 208-240 VAC, max current 12A. This change of pulse signal from the control unit means that the AC power supplying must be changed proportionally thereby increasing or decreasing its speed in relation to the signal received. For instance, a warmer temperature increases the signal strength, making the P266EFA-1K increase fans’ rotation rate to increase cooling.
