High Starting Torque: The HST motor ensures consistent performance in systems using expansion valves or capillary tubes where unbalanced pressures are common during startup

the unit failing to ignite due to "open" pressure switch codes

High Thermal Stability: Constructed with non-PCB oil and a robust aluminum casing to dissipate heat during 24/7 cooling cycles

meaning the switch is calibrated to open the electrical circuit at 165°F and automatically reset once the temperature differential drops by 30°F

Key Benefits Universal Compatibility: Supports single-stage heating/cooling
