allowing the unit to provide cooling when outdoor temperatures fall between 20°F and 50°F by monitoring 14-inch liquid line pressure

How does this differ from the original H91WA-4

What causes a 24V transformer to fail

The unit is equipped with a multi-voltage continuous duty coil that accepts 24 VAC/DC

This kit includes the necessary Teflon seal rings and sensing bulb mounting hardware to facilitate a professional-grade installation and ensure a leak-free seal on the liquid line and distributor assembly

Setra 2651006WD11A1C Pressure Transducer Els PW 17895 allowing the unit to provideThe Setra 2651006WD11A1C is a professional grade low differential pressure transducer engineered specifically for high efficiency HVAC system monitoring and VAV fan control. This unit features a 0 to 6 in. W. C. range and utilizes Setras signature all stainless steel capacitive sensing element. Unlike cheaper alternatives that rely on signal amplification, this dead ended sensor design minimizes thermal drift and hysteresis, ensuring 1% FS accuracy
