Johnson Controls TE-68NT-1N00S Temperature Sensor

The Johnson Controls TE-68NT-1N00S is a high-precision 1K Ohm Nickel Temperature Sensor designed for critical room wall-mount applications within a Building Automation System (BAS) or DDC framework. As a direct replacement for TE-67NT-2B00 and TE-6100-8, this third-generation Metastat sensor provides high-accuracy environmental monitoring with a reference resistance of 1,000 ohms at 70?F. This unit features a built-in warmer/cooler setpoint adjustment dial and a manual occupancy override button, allowing field technicians and occupants to trigger temporary scheduling overrides for improved local control. Built for durability and ease of installation, the terminal block connection accommodates 18 to 24 AWG wiring, ensuring a stable interface with Johnson Controls digital controllers. The integrated DIP switches allow for precise configuration of occupancy features and LED behavior to match specific controller requirements, while the onboard Zone Bus access port enables seamless commissioning and servicing via a 6-pin modular jack.

• 1K Ohm Nickel Element: Delivers a consistent temperature coefficient of approximately 3 ohms per degree Fahrenheit for reliable HVAC sensor feedback.
• Local Setpoint Control: Features a warmer/cooler dial for immediate occupant comfort adjustments without central system reprogramming.
• Occupancy Override: Includes a momentary push button to signal the controller for after-hours operation or immediate status changes.
• Flexible Field Wiring: Equipped with a screw terminal block to simplify installation in new or retrofit HVACR projects.
• Controller Compatibility: Fully supports Johnson Controls VMA, FEC, and other standard DDC controllers with selectable configuration switches.

Common Questions Is the TE-68NT-1N00S compatible with older TE-6700 series sensors? Yes, the TE-68NT-1N00S is the official replacement for TE-67NT-1B00, TE-67NT1N00, and TE-6100-8 models, maintaining the same 1k ohm nickel resistance curve. How do I configure the occupancy LED and override button? The unit features internal DIP switches that allow you to enable or disable the manual override pushbutton and the occupancy LED to align with your specific controller?s logic. What is the maximum wire run recommended for this nickel sensor? To maintain an accuracy error of less than 1?F, the total resistance of the sensor wiring should remain below 3 ohms. It is recommended to use 18 AWG wire for longer runs to minimize resistance-induced error.
