Model ICM333 operates as a temperature- or pressure-sensitive motor-fan-speed control, regulating head pressure by varying the amount of airflow through the condenser. By allowing for dual probes, the head-pressure control is suitable for a range of systems, including single-fan, multi-coil systems. It can help prevent evaporator freezeups, liquid-slugged compressors, low-pressure cutouts and overshoots common with on/off and pressure-switch controls.
