Description
The Johnson Controls P70AA-11B is a PENN P70 Series Pressure Control for high pressure applications. Per the manufacturer, the P70, P72 and P170 controls for high pressure applications "are designed primarily for high pressure cut-out control, head-pressure control, and condenser fan cycling control on commercial refrigeration and air conditioning applications. Controls are available in several pressure ranges and are compatible with most common refrigerants. You can also use the controls on other non-corrosive fluid applications."
A pressure-actuated bellows is connected to a pressure tap on the controlled system by a capillary or a field-installed hose; the bellows responds to system pressure changes and operates a snap-action electrical switch. An all-steel case and cover provide long-lasting, rugged protection for the internal components, and the sight-set calibrated pressure adjustment displays a visible pressure scale that is fully adjustable through the range without removing the cover on Type 1 (NEMA 1) enclosure models. In the P70 model code the first letter denotes switch action (A = SPST open-low with automatic reset, B = SPST open-low with manual reset lockout, C = SPST open-high with automatic reset, D = SPST open-high with manual reset lockout) and the second letter denotes the enclosure and adjustment style (A = Type 1 enclosure without adjustment knob, B = Type 1 enclosure with adjustment knob).

Typical applications include commercial refrigeration and air conditioning systems, and the control may also be used on air, water and other non-corrosive fluid applications. Mount the control upright and level, avoid sharp bends in the capillary tube, and use copper conductors only with all wiring made in accordance with the National Electrical Code and local regulations. Except for models specifically listed as refrigeration pressure cut out controls, use this control only as an operating control - where failure or malfunction could lead to personal injury or property damage, incorporate additional supervisory, alarm, safety or limit devices into the control system.
