The P470 Electronic Pressure Control with Display is a single-stage, On/Off, electronic pressure control with an SPDT output relay (open high or low). The P470 control uses a P399 Electronic Pressure Transducer to generate a pressure signal and WHA-P399 Wiring Harness, which eliminates many of the constraints of capillary-tube control applications. (MUST BE ORDERED SEPARATELY)

• Easy-to-read liquid crystal display (LCD) clearly displays the sensed pressure (and other control information), and in many situations pressure may be monitored without applying gauges to the controlled equipment. LED indicates relay status
• Three field-selectable pressure ranges between 0-750 psi (transducer dependent) provide the flexibility to cover most HVAC/R pressure applications
• Lockable, 3-button, front-panel touchpad deters tampering and over adjustment of control settings by unauthorized personnel.
• Built-in, adjustable, anti-short cycle time-delay reduces compressor short cycling and nuisance lockouts, which can extend compressor life
• Economical, versatile transducer and wiring harness eliminate many of the constraints of capillary control applications and allow up to a 100 ft (30.5m) cable between control and transducer
