Johnson Controls P470EB-1 Pressure Control

The Johnson Controls P470EB-1 is a high-performance electronic pressure control designed for versatile field applications in commercial refrigeration and HVAC systems. Built to replace traditional mechanical controls, this 120/240 VAC unit features a large LCD display for real-time pressure monitoring, eliminating the need for technicians to manually attach gauges during routine diagnostics. With three field-selectable operating pressure ranges—0 to 100 psi, 0 to 500 psi, and 50 to 750 psi—this single control offers multi-range flexibility to handle suction, discharge, or fan cycling tasks.

The unit utilizes a P399 electronic pressure transducer (or P499/P599 series) to deliver a precise 0.5 to 4.5 VDC input signal, effectively removing the risks associated with capillary tube leaks and vibration-induced failures. Its SPDT relay provides single-stage on/off control with 16 FLA at 120V, suitable for direct or pilot duty operation. A lockable 3-button touchpad prevents unauthorized setpoint changes, while the integrated anti-short cycle time delay protects compressors from high-frequency cycling, ensuring long-term system reliability in demanding NEMA 1 environments.

• Selectable Pressure Ranges: Covers 0-100, 0-500, and 50-750 psi with a single SKU, simplifying truck stock and field replacements.
• Electronic Precision: Provides a minimum differential as low as 5 psi with an accuracy of ±1.5% of the selected range.
• Eliminates Capillaries: Remote transducer capability allows mounting up to 100 feet away, removing refrigerant leak points and capillary vibration fatigue.
• Tamper-Resistant Configuration: Features a lockable interface and system-status indicators to maintain optimal refrigerant pressure control without interference.

• Is the transducer included? No, the P470EB-1 requires a separate P399, P499, or P599 series transducer and a WHA-P399/PDK3 wiring harness matched to your specific pressure range.
• Can multiple controls share one sensor? Yes, up to four P470 controls can be wired to a single transducer for staged equipment or manifold applications.
• What power sources are supported? This specific model (EB-1) is designed for line voltage, supporting 120 Vac or 208/240 Vac 50/60 Hz inputs.
