Lennox 99N58, manufactured by ICM Controls as model ICM326HN, is a reliable head pressure control designed to regulate condenser fan operation and maintain proper refrigerant pressure in low ambient conditions. This OEM HVAC control helps prevent excessive pressure drops that can lead to poor system performance, nuisance shutdowns, or compressor damage during cold-weather operation.
The ICM326HN is compatible with both 120 VAC and 208/240 VAC systems, making it a versatile solution for a wide range of air conditioning and heat pump applications. By cycling or modulating the condenser fan motor based on pressure input, this control ensures stable head pressure, improved efficiency, and consistent cooling performance even when outdoor temperatures drop.
