Johnson Controls – P70LB-1C Dual Pressure Control Manual Reset

P70 single and dual function pressure controls are used in commercial air conditioning and refrigeration applications. The load-carrying contacts provide direct control of A.C. motors within the control?s rating. (See cover label for the electrical rating.)

The controls can be used with R- 12, R-22, R-500, or R-502 refrigerants. Specific models for ammonia applications are also available. The MICRO-SET construction of low-pressure controls and low side of dual models permits differentials to a minimum of 5 psi (34 kPa).

Features and Benefits

• High Pressure Diff. PSIG: 65 to 95
• High Range PSIG: 100 to 500
• Low Pressure Diff. PSIG: 7 to 50
• Low Range PSIG: 20″ to 100″
• All-steel case and cover built to provide long lasting, rugged protection for internal components.
• Sight-set calibrated pressure adjustment displays a visible pressure scale, fully adjustable through the range without removing the cover (on NEMA 1 enclosure models).
• MICRO-SET differential option allows for precise control on low pressure applications.
• Independent high- and low-pressure switches (P70S and P170S Models) satisfies a variety of dual pressure application wiring requirements with a single versatile control.
• Convertible high pressure reset–auto reset or manual reset lockout (P70S and P170S Models) reduces inventory—one control can be adapted to several dual pressure applications in the field.
