Engineered with a 250-degree F fixed temperature setpoint

Efficient Thermal Management: Open enclosure design and Class B insulation prevent winding failure under standard operating loads

Optimized Flow Dynamics: Differential Cv ratings accommodate specific pressure drops across mixing ports for system stability

which safely exceeds the operating pressures typically found in R-410A refrigeration and air conditioning systems

Carrier HH18HC069 Temp Switch 326070-701 Engineered with a 250-degree FThe Carrier HH18HC069 Defrost Temp Switch is a critical field service component designed for precise evaporator coil temperature monitoring in residential and light commercial heat pump systems. This SPST thermal switch, often used as a defrost termination switch, is engineered with a fixed set point to sense frost accumulation and initiate or end the defrost cycle, ensuring optimal heat transfer and preventing compressor slugging.
