Application
The P100AP-354 is purpose-built for condenser fan cycling control, making it ideal for managing head pressure in air-cooled condensing units. By cycling the condenser fan motor in response to refrigerant system pressure, this control helps maintain optimal system efficiency, protects compressors from low ambient conditions, and extends overall equipment life. Its automatic reset feature ensures the system resumes normal operation without technician intervention once pressure returns to the cut-in set point.
