Johnson Controls NS Series Installation Manual

Applications
The vertical wallbox-mounted or 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 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 except the NS-BTF Series feature either
a temperature setpoint adjustment dial or setpoint
adjustment buttons. They also feature a °F/°C pushbutton
and an LCD designed to make adjusting the temperature
setpoint and viewing the zone temperature easier. A
warmer/cooler dial is included on NS-BTF Series 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
pushbutton to toggle between temperature and RH on the
display. These models also have the capability to set the
default display to either temperature or RH.
A °F/°C pushbutton is available on all models to provide
temperature scale options for display. A fan mode
pushbutton is also included on some models to select
the desired fan speed (AUTO-OFF-low-medium-high). An
occupancy override function is featured on all models,
which allows you to signal the controller that the space
is occupied, to request an override of time-of-day
scheduling. Rotating the setpoint dial or pressing either
setpoint adjustment button signals occupancy. See
Temperature Setpoint Adjustment/Occupancy Override
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, you can terminate the
wires connecting the network sensor to the controller
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 through
the network sensor.
Note: Since some NS Series Network Sensor features
are not supported in previous releases of Metasys
or Facility Explorer system software, we recommend
that you keep the system software up to date.

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.
Important: Le NS Series Network Sensor est
destiné à transmettre des données entrantes à
un équipement dans des conditions normales
de fonctionnement. Lorsqu'une défaillance ou
un dysfonctionnement du network sensor risque
de provoquer des blessures ou d'endommager
l'équipement contrôlé ou un autre équipement, la
conception du système de contrôle doit intégrer des
dispositifs de protection supplémentaires. Veiller
dans ce cas à intégrer de façon permanente d'autres
dispositifs, tels que des systèmes de supervision
ou d'alarme, ou des dispositifs de sécurité ou de
limitation, ayant une fonction d'avertissement
ou de protection en cas de défaillance ou de
dysfonctionnement du network sensor. Approved
