this component is designed to withstand the higher operating pressures associated with modern R-410A heat pump systems

What furnace models does the Fasco A160 replace

the actuator will move to the position dictated by the signal minimum (typically closed) unless the power source itself is interrupted

do not plug unused ports as it will interfere with the internal diaphragm logic and signal selection accuracy

such as diverting supply lines between two different branch outputs or feeding/exhausting HVAC branch lines based on pressure thresholds
