Johnson Controls HE-69520NP-0 Sensor

The Johnson Controls HE-69520NP-0 is a high-precision duct mount humidity and temperature sensor designed for demanding HVAC applications. This unit serves as the direct replacement for the legacy HE-67P2-0N00P model, providing a seamless upgrade path for building automation systems. It features a high-accuracy 1K ohm Platinum RTD (Class A) temperature element and a capacitive humidity sensor that delivers a 0-10 VDC proportional signal. The HE-69520NP-0 is calibrated to NIST-traceable standards, ensuring ±2% RH accuracy across a wide range of operating conditions. Its all-plastic, UL-rated plenum enclosure and 6.25-inch probe are engineered for superior thermal performance and environmental resistance. Designed for easy integration, this duct humidity transmitter supports internal jumpers for user-selectable output ranges, making it a versatile choice for both new installations and retrofits involving constant or variable air volume (VAV) systems.

• Dual-Function Sensing: Combines relative humidity and temperature monitoring into a single HE-69520NP-0 device, reducing wiring complexity and installation time.
• NIST-Traceable Accuracy: Verified ±2% RH accuracy ensures precise enthalpy calculations for energy-efficient economizer control.
• Rugged Construction: Features a blue plastic housing compliant with UL flammability ratings for safe duct humidity sensor deployment in plenum spaces.
• Versatile Powering: Compatible with 24 VAC/VDC power sources, drawing minimal current for low-voltage control loops.
• Legacy Compatibility: Engineered specifically to replace the HE-67P2-0N00P without requiring significant mounting adjustments.

How do I wire the HE-69520NP-0 for 0-10V output?
The unit utilizes a standard 5-terminal block. Connect the 24V supply to PWR and COM, and take the humidity signal from VOUT. Ensure the internal jumper is set to the 10V position if a 0-5V range is not required by your controller.

Is this sensor compatible with non-Johnson Controls BAS?
Yes, the HE-69520NP-0 provides a standard 0-10 VDC humidity signal and a 1000 ohm platinum RTD resistance output, making it compatible with most third-party building automation systems.

Can I use this sensor in high-condensation environments?
While the HE-69520NP-0 features a protective membrane for the sensing element, it is intended for use in non-condensing environments up to an 85°F maximum dew point to prevent sensor saturation.
