Aaon P77560 Fan Cycle Switch 270 PSI/CI 150 PSI/CO

The Aaon P77560 Fan Cycle Switch is used in HVAC systems, especially in commercial rooftops and air handlers. It has a cut-in pressure of 270Psi and a cutout pressure of 150psi. This switch operates the fan motor to cool the refrigerant rises to a pressure of 270 PSI. The switch turns off the fan when the pressure drops to 150 PSI. This on/off cycling assists in maintaining the system pressure at the correct level, preventing low head pressures and also saves energy in that the fan is only used when necessary while at the same time extending the life of the HVAC equipment.
