Description
Johnson Controls P70AA-118 Single Pole High Pressure Control
The Johnson Controls P70AA-118 is a single-pole, single-throw (SPST) high pressure control engineered for reliable head pressure fan cycling in commercial and industrial refrigeration and air conditioning systems. With a Close High/Open Low switching action, this control energizes the circuit as pressure rises and de-energizes it as pressure falls, making it ideal for condenser fan cycling applications where precise pressure management is critical.
Key Features
- SPST (Single Pole, Single Throw) switching configuration
- Close High/Open Low action for head pressure fan cycling
- Pressure control range: 100 PSI to 400 PSI
- Adjustable differential range: 35 PSI to 200 PSI
- Maximum allowable overpressure: 475 PSIG
- 36″ capillary tube for flexible remote sensing installation
- 1/4″ flare nut pressure connector for secure, leak-free connection
Application
The P70AA-118 is specifically designed for head pressure fan cycling duty, allowing technicians to maintain optimal condensing pressure by cycling condenser fans on and off in response to refrigerant system pressure. The wide differential range provides flexible setpoint customization to match the demands of diverse refrigeration and HVAC systems.
