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 Va riable 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 ter m ina t ed
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.

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.

Mounting

Note: For wallbox-mounted installations, the

NS Series Network Sensor is intended to be mounted
on a vertically roughed-in wallbox only; do not attempt
to mount the network sensor on a horizontally
roughed-in wallbox.

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:

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. For vertical wallbox-mounted installations, proceed
to Step 4. For surface-mounted installations,
proceed to Step 7.

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

5. Align the mounting base on the wallbox.

Note: Confirm that the mounting base is positioned
with the proper edge up. The mounting base is
positioned properly when the security screw is located
on the top edge of the base.

6. Secure the mounting base to the wallbox using the
two No. 6 pan-head mounting screws included with
the unit. Proceed to Step 9.

7. 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.

Note: Confirm that the mounting base is positioned
with the proper edge up. The mounting base is
positioned properly when the security screw is located
on the top edge of the base.

8. Secure the mounting base to the wall using the
appropriate mounting hardware (field furnished).
Proceed to Step 9.

Setup and Adjustments

°F/°C Temperature Mode Selection

All 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-BHR710x-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.

Network Sensor Addressing

Most network sensors have a default device address of
199 on the SA Bus. For the NS-BTB7003-0 averaging
model, the sensor address must be set on the
dual-switch DIP switch block on the network sensor
Printed Wire Board (PWB).
