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 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.
Surface-Mounted NS Series Network Sensors with LCD Installation
Refer to the QuickLIT website
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.
