The Johnson Controls D352AA-2 Digital Display is a professional-grade pressure indication module designed for high-pressure HVACR environments. Engineered as the direct replacement for the D352AA-1, this unit provides real-time monitoring and setpoint visualization when integrated with P352 and P352P Series controls. It features a high-contrast 3-digit LCD that ensures accurate diagnostics for technicians managing critical system parameters. The module supports a wide operating range, remaining reliable in ambient temperatures from -30 to 150°F, and is housed in a NEMA 1 high-impact thermoplastic case for maximum durability on the job site. For high-pressure applications, the D352AA-2 0-750 psi display offers precise data tracking with built-in error detection. It signals an out of range setpoint value if parameters exceed 700 Psi and triggers an out of range sensor value alert if readings surpass 750 Psi. Installation is streamlined via a 5-pin connector that interfaces directly with the system 350 pressure module, and the unit supports both surface and DIN rail mounting. By holding the front-facing button for three seconds, contractors can instantly verify current setpoints, making the Johnson Controls digital pressure display an essential tool for rapid system troubleshooting. Key Benefits Seamless Integration: Designed specifically for use with P352 Series pressure controls and P499 transmitters. Legacy Compatibility: Functions as the official D352AA-1 replacement to simplify site upgrades. High-Pressure Precision: Monitors systems with pressures up to 750 Psi with clear digital accuracy. Versatile Mounting: Supports standard DIN rail or surface mounting configurations for flexible control panel layouts. Field Diagnostics: Front-access setpoint button allows for immediate verification of control logic without external tools. Common Questions Is the D352AA-2 compatible with older D352AA-1 systems? Yes, the D352AA-2 is the direct replacement for D352AA-1 and fits perfectly into existing System 350 architectures without requiring modifications. What does it mean if the display shows an out of range sensor value? This indicates that the pressure sensed by the P499 or DPT2640 transmitter has exceeded 750 Psi, which is the maximum limit for this specific HVAC pressure display module. Can I mount this display remotely from the control module? Yes, it can be mounted up to 50 feet away using a WHA29A series cable to provide pressure visibility at a more accessible location.
