Johnson Controls HL-69158NP-0 Temperature Sensor

The Johnson Controls HL-69158NP-0 is a high-precision multi-function humidity and temperature sensor, serving as the direct replacement for HL-67N5-8N00P. This duct probe sensor is engineered for versatile field applications, functioning as a high-limit or proportional override controller, a stand-alone proportional controller, or a two-position controller. By integrating a 1K ohm nickel RTD thin-film element, it provides reliable temperature data with resistance calibrated at 70°F (21°C). The unit features an adjustable RH setpoint (60% to 95%) and a proportional band (5% to 30%), allowing technicians to mitigate condensation by overriding system demand as humidity levels approach user-defined limits. Designed with an all-plastic, polycarbonate enclosure, the sensor effectively reduces thermal biasing and eliminates the need for complex thermal compensation. Whether utilizing 0-10VDC or 0-20mA signals, this Johnson Controls sensor ensures seamless integration with AHU, VAV, and UNT controllers for robust climate management.

• Enhanced Compatibility: Serves as the official replacement for HL-67N5-8N00P, facilitating straightforward retrofits in existing HVAC control systems.
• Dual-Function Monitoring: Combines duct humidity and temperature sensing into a single probe, reducing installation time and wiring complexity.
• Precision humidity control: Features an adjustable RH setpoint and proportional override logic to prevent duct moisture buildup and energy waste.
• High-Accuracy RTD: Utilizes a 1K ohm nickel temperature sensor with a thin-film material for consistent resistance tracking and long-term stability.
• Flexible Output Signals: Supports both 0-10VDC voltage and 0-20mA current loop configurations to match various building automation head-ends.

Is the HL-69158NP-0 compatible with my older 1K nickel system?
Yes, the probe includes an integrated 1K ohm nickel RTD element, providing the standard resistance-to-temperature curve required for legacy Johnson Controls and compatible building automation systems.

Does this unit function without an external controller?
Absolutely. The HL-69158NP-0 can operate as a stand-alone controller, utilizing its internal SPST normally open (N.O.) relay for two-position control or its analog output for proportional humidifier modulation.

How does this sensor help reduce energy consumption?
By accurately regulating duct relative humidity through proportional override, the sensor prevents over-humidification and associated condensation, ensuring equipment runs only as needed for the load.
