NSB8BTN340-0 Johnson Controls Network Sensor

Overview

The Johnson Controls NSB8BTN340-0 is a commercial-grade room network temperature sensor designed to function directly with building automation systems (BAS), including Metasys and Facility Explorer systems. It monitors zone temperature and transmits data over a BACnet MS/TP network via the Sensor/Actuator (SA) bus, offering precise environmental control and local occupant interaction.

Features

• Full-color graphical LCD user interface display for clear visibility of space conditions.
• Integrated user interface allowing on-site setpoint adjustments, fan speed control (automatic, off, low, medium, high), and occupancy override.
• White surface-mount enclosure featuring the Johnson Controls logo that blends cleanly with modern commercial interiors.
• Built-in screen lockout feature to prevent unauthorized tampering with settings.
• Selectable light or dark color themes and adjustable sleep mode (dim or turn off) for the display.
• Supports temperature scale toggling between degrees Fahrenheit and Celsius.
• Includes modular phone jacks and screw terminals for versatile wiring terminations.
