NSB8BTN240-0 Johnson Controls Network Temperature Sensor

Overview

The Johnson Controls NSB8BTN240-0 is a wall-mounted network temperature sensor from the NS8000 Series designed for commercial building automation and HVAC control applications. Finished in white with a branded logo faceplate, this sensor monitors zone temperature and transmits the data to a controller over a network using the BACnet MS/TP protocol. It features an integrated backlit fixed-segment LCD display that provides real-time local environmental feedback to occupants and allows for direct temperature setpoint adjustments, combining clean aesthetics with user-friendly functionality.

Features

• Network temperature sensor with BACnet MS/TP protocol communication for seamless integration with Johnson Controls building automation systems (BAS) like Metasys and Facility Explorer.
• High-contrast, large backlit fixed-segment LCD display for enhanced readability of zone temperature and setpoint values.
• Built-in capability for simple temperature setpoint adjustment or Warmer/Cooler comfort control mode directly from the display.
• Field-selectable default display settings allowing users to toggle between temperature, relative humidity, or temperature setpoint for continuous viewing.
• Fahrenheit and Celsius (°F/°C) selectable display options.
• Temporary occupancy function providing a timed override command to signal an occupied state to the controller.
• Built-in screen lockout feature to prevent unauthorized sensor tampering in public or high-traffic spaces.
• Compact, low-profile white housing with a branded JCI logo faceplate designed to blend smoothly into standard commercial interiors.
