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 208-240 volt, single-phase motors up to 3 horsepower, and 208-220 volt, 3-phase motors up to 5 horsepower.
