Aaon P58840 Mixed Air Sensor

The Aaon P58840 Mixed Air Sensor is a critical OEM component designed for high-precision thermal monitoring in HVAC air handling units and rooftop systems. As a direct replacement for legacy solid-state sensors like the Honeywell C7150B1004, this unit provides the essential data required for economizer control and MA temperature reset strategies. Engineered to withstand demanding environments, it features a 250-degree max ambient temperature rating and a robust housing suitable for duct or discharge mounting. This thermistor-based sensor ensures your controller maintains the correct mixing ratio of return and outdoor air, preventing coil freeze-up and optimizing compressor staging. For technicians servicing Aaon RN or RQ series equipment, using this genuine Aaon replacement part is vital for maintaining factory calibration and system communication integrity. Its 24V AC/DC compatibility and rapid response time allow for near-instantaneous adjustments to dampers, ensuring stable discharge air temperatures even during rapid outdoor ambient shifts.

• Broad Compatibility: Seamlessly integrates with Aaon building automation products and standard 24V controllers.
• High Thermal Tolerance: Rated for up to 250°F ambient temperature, making it ideal for high-heat discharge applications.
• Precision Accuracy: Provides reliable mixed air temperature readings to prevent setpoint hunting and unnecessary cycling.
• Durable Construction: Built with a weather-resistant housing to ensure long-term field performance in various duct conditions.

Is the Aaon P58840 compatible with non-Aaon controllers?
Yes, as long as the controller supports 10k-ohm (or specified thermistor curve) inputs and 24V power, though it is optimized for Aaon OEM HVAC systems.

Can this sensor be used for discharge air monitoring?
Absolutely. Its high max ambient temperature rating allows it to function as either a Mixed Air or Discharge Air sensor depending on system configuration.

What happens if this sensor fails?
Failure typically triggers an economizer fault or forces the outdoor air dampers to a minimum position, potentially leading to reduced indoor air quality or cooling inefficiencies.
