Applications

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.

Some models 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 certain models
to provide temperature scale options for display.
A fan mode push button 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 the user to signal the controller that the sp ace 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. Select models
offer stylish black enclosures to suit specific
architectural and interior design needs.

Note: Since some NS Series Network Sensor
features are not supported in previous releases of
Metasys® or Facility Explorer system software, it is
recommended that the system software be kept up to
date.

IMPORTANT: The surface-mounted 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 surface-mounted 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.

brouilleur du Canada.

Installation

Special Tools Needed

A 1/16 in. (1.5 mm) Allen wrench or a Johnson Controls
T-4000-119 Allen-Head Adjustment Tool is required
during installation.

Location Considerations

Locate the network sensor:

• on a partitioning wall, approximately 5 ft (1.5 m)
above the floor in a location of average
temperature

• away from direct sunlight, radiant heat, outside
walls, outside doors, air discharge grills, or
stairwells; and from behind doors

• away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or
sources of electrical interference

Note: The network sensor is shock and vibration
resistant; however, be careful not to drop the unit or
mount it where it could be exposed to excessive
vibration.

The following ambient operating conditions apply:

• Temperature: 32 to 104°F (0 to 40°C)

• Humidity: 10 to 90% Relative Humidity (RH),
noncondensing; 85°F (29°C) maximum dew point

To mount the network sensor to the wall:

1. Use a 1/16 in. (1.5 mm) Allen wrench or
Johnson Controls T-4000-119 Allen-Head
Adjustment Tool to loosen the security screw on
the top of the unit.

2. Insert a coin into the slot next to the security screw
location, then carefully pry the top edge of the
sensor assembly away from its mounting base and
remove.

IMPORTANT: Do not remove the Printed Circuit
Board (PCB). Removing the PCB voids the product
warranty.

3. Pull out approximately 6 in. (152 mm) of cable from
the wall, and insert the cable through the hole in
the mounting base.

4. Align the mounting base on the wall, and use the
base as a template to mark the location of the two
mounting holes on the surface.

Setup and Adjustments

°F/°C Temperature Mode Selection

Certain models include a °F/°C push button on the face
of the network sensor to provide temperature scale
options for display. Pressing the push button toggles
the temperature mode between Fahrenheit and Celsius
on the LCD.

Temperature/RH Mode Selection

Temperature/RH models include a push button on the
face of the network sensor to allow occupants to view
the temperature and relative humidity of the zone.
Pressing the push button toggles between temperature
and RH on the LCD. The LCD defaults to temperature
5 seconds after the push button is released.

The NS-AHR710x-0 and NS-APR710x-0 models also
have the capability to set the desired default display to
either temperature or RH. Follow this procedure to
change the default display on these models:

1. If the display backlight is off, press and release the
push button to illuminate the backlight. If the
display backlight is already on, proceed to Step 2.

2. Press and hold the push button for 5 seconds to
switch to the desired default display (either
temperature or RH).

Note: The desired default display will flash for
5 seconds. After the display stops flashing, the new
default display is in effect.

Temperature Setpoint Adjustment/Occupancy Override

The large dial on the face of the network sensor
functions in two ways: to increase or decrease the
setpoint temperature, and to change the controller
mode from unoccupied and occupied. When the dial
is rotated slightly, the backlight on the LCD lights up. If
the dial is rotated slightly again, and the controller is in
the unoccupied mode, the controller changes from the
after-normal-working-hours setback mode to the
normal-working-hours comfort mo de . To adjust the
setpoint, continue rotating the dial until the current
setpoint is displayed and flashing. Turn the dial
clockwise to increase the setpoint and
counterclockwise to decrease the setpoint. S top turning
the dial once the desired setpoint is reached. The new
setpoint stops flashing and becomes fixed after a few
seconds.

3. Release the push button; the desired display is
now the new default display.

Fan Mode Selection

Some models include a fan mode push button on th e
face of the network sensor to select the desired fan
speed. Pressing the push button toggles the fan speed
between AUTO-OFF-low-medium-high on the LCD.

Network Sensor Addressing

Most network sensors have a default device address of
199 on the SA Bus. For averaging models, the sensor
address must be set on the dual-switch DIP switch
block on the network sensor Printed Wire Board
(PWB).
