P470 Electronic Pressure Control with Display Description The P470 Electronic Pressure Control with Display is a single-stage, on and off, electronic pressure control with a single-pole, double-throw (SPDT) output relay. You can field-set the P470 control to operate in one of the following three pressure ranges, as either an open-high or open-low control: 0 psi to 100 psi, 0 psi to 500 psi, or 50 psi to 750 psi. The P470 control has a large LCD that displays the sensed pressure, other system-status indicators, and adjustable setpoints in the programming mode. The P470 control has a lockable, three-button touchpad for adjusting setpoints, and a front-panel LED that indicates the output relay status. The P470 control uses a P599 Series Electronic Pressure Transducer and a WHA-PDK3 wiring harness to sense system pressure. This arrangement eliminates almost all refrigerant leaks because there are no capillaries or bellows to break or fail. Refer to the P470 Electronic Pressure Control with Display Product/Technical Bulletin (LIT-125528) for important product application information. Features • Easy-to-read LCD • Three field-selectable pressure ranges between 0 psi and 750 psi • 24 VAC, and 120 VAC or 208/240 VAC models • Lockable, three-button, front-panel touchpad • Built-in, adjustable, anti-short cycle time-delay • Uses an economical and versatile transducer and wiring harness Selection chart Note: P470 Controls do not include a transducer or wiring harness. A P599 transducer and a wiring harness must be purchased separately. Match the transducer to the selected pressure range.
