Johnson Controls TE-68NT-0N00S Temperature Sensor

The Johnson Controls TE-68NT-0N00S is a high-precision 1K Ohm Nickel Temperature Sensor engineered specifically for wall-mount applications within commercial building automation systems. As a veteran-grade HVAC RTD sensor, it utilizes a 1,000-ohm thin-film nickel sensing element with a resistance coefficient of approximately 3 ohms per ?F, ensuring stable and repeatable linear feedback to Johnson Controls digital controllers. This specific model features a terminal block connection with screw-type terminals, making it a reliable choice for field technicians using 18 to 24 AWG wiring. Designed for versatility, the TE-6800 series enclosure includes a 6-pin Zone Bus access port, allowing for streamlined commissioning via HVAC PRO software without removing the cover. Its white thermoplastic housing is vibration resistant and optimized for ambient operating conditions between 32?F and 131?F, providing the mechanical durability required for demanding mechanical room or office environments.

Key Benefits

• Superior accuracy of ?0.34?F at 70?F ensures precise BAS temperature monitoring and optimized occupant comfort.
• Integrated terminal block connection simplifies field installation and provides secure, low-resistance termination.
• Front-access 6-pin Zone Bus port allows for rapid system diagnostics and controller servicing via a laptop and CVTPRO converter.
• Internal DIP switches enable technicians to configure local occupancy features and LED behavior to match specific sequence-of-operation requirements.
• Standard 80 x 80 mm footprint allows for direct wall mounting, while compatibility with the NS-WALLPLATE-0 accessory facilitates mounting to standard electrical boxes.

Common Questions

What is the maximum wire run recommended for this nickel sensor?
To maintain an error rate below 1?F, the total resistance of all sensor wiring should be kept under 3 ohms. This typically limits 18 AWG wire runs to 250 feet and 24 AWG runs to 50 feet.

Can this sensor be used with non-Johnson Controls equipment?
While functionally a standard 1k ohm nickel RTD, these units are specifically optimized for Johnson Controls digital controllers and VMA series modules to ensure full compatibility with scaling and offset parameters.

How do I resolve inaccurate temperature readings after installation?
First, verify the sensor is mounted away from drafts, direct sunlight, or heat-producing equipment. Check terminal connections for high resistance and ensure the sensor leads are not run in the same conduit as high-voltage line power.
