Johnson Controls HE-68N3-1N00WS Humidity Transmitter

The Johnson Controls HE-68N3-1N00WS is a professional-grade wall mount humidity transmitter engineered for precise atmospheric monitoring in commercial HVAC systems. This unit features a high-accuracy ±3% humidity sensor integrated with a 1000 Ohm thin film nickel temperature sensing element, providing reliable dual-mode feedback for environmental controllers. Designed for versatility in the field, it accepts a wide input range of 14 to 30 Vdc or 20 to 30 Vac, making it compatible with most legacy and modern building automation systems. As a direct replacement for HE-67N3-2B00W, this model simplifies retrofits by maintaining consistent wiring logic and mounting footprints. The interface includes a warmer/cooler temperature setpoint adjustment and a manual override, allowing for localized zone tuning without compromising the master control sequence. For technicians managing ductless or centralized air handling units, this transmitter ensures long-term stability and minimal drift in demanding indoor environments.

Key Benefits

• Dual Sensing Capability: Combines relative humidity and temperature monitoring into a single low-profile housing to reduce installation labor.
• Nickel RTD Integration: Uses a 1000 Ohm thin film nickel element for high-precision thermal tracking and linear response.
• Field Adjustment Tools: Integrated setpoint slider and override button facilitate immediate zone comfort adjustments for occupants.
• Universal Power Compatibility: Supports both AC and DC voltage inputs to accommodate varied controller power supplies.
• Seamless Retrofit: Functions as the factory-authorized successor to the discontinued HE-67N3-2B00W series.

Common Questions

Is the HE-68N3-1N00WS compatible with non-Johnson Controls systems?
Yes, as long as your controller accepts a 1000 Ohm nickel input for temperature and the standard humidity output signal, this transmitter can be integrated into most third-party BAS platforms.

Will this unit fit the mounting base of the old HE-6700 series?
This model is the direct replacement for the HE-67N3-2B00W and is designed to mount securely to standard electrical boxes or directly to the wall with minimal modification.

How does the override button function within the system?
The override button momentarily shorts or changes the resistance on the sensor circuit, signaling the controller to enter occupied mode or bypass a schedule.
