Lennox Low Ambient Cutoff (NCO-45F08) The Lennox Low Ambient Cutoff (NCO-45F08) is a critical control that operates with Lennox equipment to maintain optimal system performance in challenging low-temperature conditions. This advanced device effectively prevents compressor short cycling and refrigerant migration, preserving system integrity and enhancing its operational efficiency. The NCO-45F08 is designed to disrupt the heat pump operation when outside temperatures fall below the factory-set low ambient temperature. This action allows the system to avoid potentially damaging compressor operation in excessively cold conditions, preventing premature wear and potential breakdowns. Additionally, it prevents refrigerant migration from the outdoor unit to the indoor unit, mitigating performance problems and safeguarding the system's refrigeration cycle. By integrating the NCO-45F08 into Lennox equipment, you can ensure reliable and efficient system performance, minimizing costly repairs and optimizing system longevity. Its seamless functionality and advanced protection features make it a valuable addition to any Lennox HVAC system.
