Aaon R37200 Fan Cycle Switch 320-475 PSI R410A

The Aaon R37200 Fan Cycle Switch is specifically for HVAC systems that use R410A refrigerant. This switch works in pressure range from 320-475PSI and turns the condenser fan motor on/off depending on refrigerant pressure. Through this cycling action, system performance is improved and exact head pressure is kept at acceptable levels especially when outside temperature is low or cooling load is minimal. Advantages include increased system performance, decreased energy use by avoiding unnecessary fan operation, and increased system dependability by avoiding low head pressures that can harm compressors.
