Applications
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. 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.
Some models also allow occupants to view the
Relative Humidity (RH) of the zone; these models
include a push button to toggle between temperature
and RH on the display. These models also have the
capability to set the desired default display to either
temperature or RH.
A °F/°C push button is available on all models to
provide temperature scale options for display. An
occupancy override function is featured on all models,
which allows the user to signal the controller that the
space is occupied, to request an override of
time-of-day scheduling. Rotating the setpoint dial
signals occupancy. See Temperature Setpoint
Adjustment/Occupancy Override for more information.

Select models in this series also provide Variable Air
Volume (VAV) balancing functionality. These models
look like and perform similarly to the other network
sensors but have the added capability of serving as a
tool to balance a VAV box.
Depending on the model chosen, the wires connecting
the network sensor to the controller can be terminated
using either a modular jack or screw terminal block,
offering wiring flexibility.
Note: Models featuring a modular jack are not
intended for installations where daisy chaining to the
MS/TP Bus is required.
All models include an SA Bus access port for
connecting accessories to access the SA Bus. This
feature allows a technician to commission or service
the controller via the network sensor.
IMPORTANT: The NS Series Network Sensor is
intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the network sensor could lead to
personal injury or property damage to the controlled
equipment or other property, additional precautions
must be designed into the control system.
Incorporate and maintain other devices, such as
supervisory or alarm systems or safety or limit
controls, intended to warn of or protect against
failure or malfunction of the network sensor.
