Description
The Lennox 15M22 High Altitude Pressure Switch is an essential accessory exclusively for Lennox HVAC systems that work in high altitudes, which are above 7500 feet. Changes in pressure with height hence the boiling points are influenced as pressures within the refrigerant loops reduce. This pressure switch has the essential responsibility of ensuring that the operation of the respective systems under these conditions attained the preferred safety levels. It also continuously measures the refrigerant pressure, the standard pressure switches may not operate properly at high altitudes.
