Use a multimeter to check for continuity across the terminals while the switch is at room temperature

allowing for the dynamic adjustment of heating and cooling cycles based on outdoor thermal loads

this assembly is the primary pressure-sensing component that translates water level changes into mechanical action for the switch head

This heat pump reversing valve utilizes a high-durability slide mechanism to shift between heating and cooling modes efficiently

Midpoint Ground Design: Optimizes safety and electrical balance during continuous or intermittent duty
