ICM Controls ICM713-LF ECM Head Pressure Control

The ICM Controls ICM713-LF ECM Head Pressure Control is an electronic module to regulate condenser fan operation based on conditions. It works by using temperature sensor inputs and a pulse-width-modulated signal to adjust the speed of fan motors, supporting maintaining stable refrigerant during varying outdoor load conditions. In residential and light commercial air conditioning and heat pump systems, it is installed in the outdoor unit control compartment and wired into the fan motor and sensor circuit used in HVAC systems.
