The Johnson Controls NS-AHA7001-0 network zone sensor
The surface-mounted NS Series Network Sensor with 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. Models in this series monitor the temperature setpoint, zone temperature, and humidity, and transmit this data to a field controller on the Sensor Actuator (SA) Bus.
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
