Johnson Controls P470FB-1C Penn Series P470 Electronic Pressure Control with Digital Display - Low Voltage HVAC System Pressure Regulator for Commercial & Industrial Applications

The P470 Electronic Pressure Control with Display is a single-stage, On/Off, electronic pressure control with a single-pole, double-throw (SPDT) 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 set points in the programming mode. The P470 Control has a lockable, three-button touchpad for adjusting set points, and a front-panel LED that indicates the output relay status. The P470 Control uses a P499 Electronic Pressure Transducer in conjunction with a WHA-PDK3 Wiring Harness to sense system pressure. This arrangement virtually eliminates the chance of a refrigerant leak because there are no capillaries or bellows to break or fail.
