The P470 Electronic Pressure Control with Display is a single-stage, On/Off, electronic pressure control with an SPDT (Single-Pole, Double-Throw) output relay. The control may be field set to operate in one of three pressure ranges (0 to 100 psi, 0 to 500 psi, or 50 to 750 psi), as either an open-high or open-low control. The P470 control features a large LCD that displays the sensed pressure and other system-status indicators, as well as the adjustable setpoints in the programming mode. The P470 control has a lockable,3-button touchpad for adjusting setpoints, and a front-panel LED (Light-Emitting Diode) that indicates the output relay status. The P470 control uses a P499 Electronic Pressure Transducer to generate a pressure signal and a WHA-PKD3 Wiring Harness, which eliminates many of the constraints of capillary-tube control applications.Features: 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 equipmentthree field-selectable pressure ranges between 0-750 psi provide the flexibility to cover most Heating, Ventilating, Air Conditioning, and Refrigeration (HVAC/R) pressure applications24 VAC, and 120 or 208/240 VAC models increase application options, with two controls that cover most common voltageslockable, 3-button, front-panel touchpad deters tampering and over adjustment of control settings by unauthorized personnelbuilt-in, adjustable, anti-short cycle time-delay reduces compressor short cycling and nuisance lockouts, which can extend compressor lifeeconomical, versatile transducer and wiring harness eliminate many of the constraints of capillary control applications and allow up to a 100 ft (30.5 m) cable between control and transducerup to four P470 controls may be used withone P499 transducer Product Specifications BRANDJohnson Controls POWER REQUIREMENTS120 or 208/240 VAC LIMITED WARRANTY YEARS1
