Application
The P100AP-4 is ideal for controlling condenser fan motors based on refrigerant head pressure. When system pressure drops to 170 PSIG, the control opens the circuit to cycle the condenser fan off, conserving energy and protecting the system. The fan circuit is re-energized automatically when pressure rises back to 250 PSIG. This pressure-based cycling strategy helps maintain optimal condensing pressure across varying ambient conditions, improving system efficiency and equipment longevity.
