Description

Johnson Controls PENN P70MA-1C Dual Pressure Control

The P70, P72, and P170 Controls for Dual Pressure Applications are designed primarily for use as combination high- and low-pressure controls on commercial refrigeration and air conditioning applications. These controls are available in several pressure ranges and are compatible with most common refrigerants.

Ammonia compatible models are also available. These controls respond directly to system pressure changes on both high and low sides, and can provide single-device control of the compressor. Controls are available in several different electrical ratings and switch configurations, including independent high- and low-pressure switches (on P70S and P170S models).

The P72 models provide direct control of 208-to-240-volt, single-phase motors up to three horsepower, and 208 to 220 volt, three-phase motors up to five horsepower. Refer to the P70, P72, and P170 Series Controls for Dual Pressure Applications Product Bulletin (LIT-125455) for important product application information.

  • 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.

Applications

  • NEMA 1 enclosures are standard on most models. NEMA 3R enclosures are also available.
  • P70S and P170S models have independently operated high- and low-pressure single-pole, double-throw (SPDT) switches that can be wired to satisfy a variety of control requirements.
  • These adaptable controls also come with a high-pressure manual reset lockout mechanism that may be converted to automatic reset.
  • P70L, M, N, and P170L, M, N models have a single-pole, single-throw (SPST) switch. Models are available with automatic or manual reset lockout options.
  • Models with manual reset are available with either high-side-only manual reset, or low-side and high-side manual reset.
  • Ammonia compatible models are also available (P70L and P70M only).
  • P72 models have a double-pole, single-throw (DPST) switch with load-carrying contacts that can provide direct control of 208 to 240 VAC, single-phase motors up to 3 hp, and 208 to 220 VAC, three-phase motors up to 5 hp.
  • See the DPST Electrical Ratings (P72L, M, and N Types) that follow.
  • Some models are available with Limited Knob Adjustment, which restricts adjustment of the pressure settings and deters over-adjustment or tampering.
  • Repair information If the P70, P72, and P170 Series Controls for dual pressure applications fail to operate within its specifications, replace the unit.
  • For a replacement control, contact the nearest Johnson Controls® representative.
