Applications from manufacturer:

The vertical wallbox-mounted or surface-mounted NS Series Network Sensor with Liquid Crystal Display (LCD) is an electronic zone sensor designed to function directly with Johnson Controls® BACnet® Master-Slave/Token-Passing (MS/TP) digital controllers in Heating, Ventilating, and Air Conditioning (HVAC) systems.

All models feature a temperature setpoint dial and LCD designed to make adjusting the temperature setpoint and viewing the zone temperature easier. A warmer/cooler dial is included on certain models for minor temperature adjustments from the setpoint.
