The NS Series Network Sensor offering includes NS Series Network Zone Sensors and NS Series Network Discharge Air Sensors. The NS Series Network Sensors are designed to function directly with Metasys® system Field Equipment Controllers (FECs), Input/Output Modules (IOMs), VAV Modular Assembly (VMA16) Controllers, and Facility Explorer FX-PC Series Programmable Controllers (FX-PCGs, FX-PCVs, and FX-PCXs).
The majority of NS Series Network Zone Sensors monitor room temperature; however, options are available to also monitor zone humidity, carbon dioxide (CO2), local temperature setpoint adjustments, and other variables. This data is transmitted to a controller on the Sensor Actuator (SA) Bus.
Some models of NS Series Network Zone Sensors include an onboard passive infrared (PIR) occupancy sensor that detects motion to determine if a space is occupied. This feature maximizes up to 30% energy savings in high-energy usage environments such as schools, dormitories, offices, hospitals, and hotels by adjusting the temperature of the space based on the occupancy status. In addition, the PIR occupancy sensor facilitates trending of floor space usage in these environments.
The NS Series Network Zone Sensors include models with a temperature setpoint dial and LCD that allows occupants to view the zone temperature, Relative Humidity (RH), and view and adjust the zone temperature setpoint. Some temperature and humidity 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 fan mode push button is included to set the desired fan speed (AUTO-OFF-low-medium-high). An occupancy override function allows the user to signal to the controller that the zone is occupied to override the scheduled mode. Some models have DIP switches to set a unique address for applications that require multiple sensors.
For communication wiring flexibility, the wires connecting the network zone sensor to a controller can be terminated using a modular jack or screw terminals. Note: Mixing of phone jack and screw terminal devices on the same SA bus segment must be avoided.
Each network sensor includes an SA Bus access port to allow accessories to access the SA Bus. This plug allows accessories to service or commission the connected controller or gain access to any other controller on the same Field Controller (FC) Bus.
The NS Series Network Zone Sensor offering includes models that can be surface mounted, vertical wallbox mounted, or flush mounted to meet the requirements of the specific application. Some NS Series Sensor models are designed to assist with the California Energy Code (Title 24). Select models offer stylish black enclosures to suit specific architectural and interior design needs.
The NS Series Network Discharge Air Sensors monitor the duct temperature, typically at the discharge of the VAV box, and transmit this data to a local controller on the SA Bus using the 10 ft (305 cm) wiring lead included with the unit. The 10 ft (305 cm) wiring lead consists of four 22 AWG (0.6 mm) trade size color-coded wires encased in a plenum-rated jacket. Each of the wires is stripped and tinned for easy connection to the SA Bus screw terminal block.
The NS Series Network Discharge Air Sensors are available with either a 4- or 8-in. (102 or 203 mm) temperature probe. All models include DIP switches for applications requiring multiple discharge air sensors, each with a unique DIP switch address

Outdoor and surface temperature sensors monitor and transmit changes in temperature to the building control system. Specific devices within the range are compatible with most North American building automation systems. All sensors incorporate precision temperature sensing elements to accurately and reliably measure temperature. Outdoor temperature sensors are used to monitor the temperature of outdoor air. This variable is often used in a variety of HVAC control strategies, including outdoor reset and building ventilation. Pipe surface temperature sensors are often used in place on immersion type sensors, particularly in cases where sensor installation occurs after the system if filled.

  • High Degree of Accuracy
  • LCD Display Option
  • Analog or Digital Temperature Setpoint
  • Occupancy Override Button
The QFA Series Room Temperature, Relative Humidity, and Relative Humidity/Temperature Sensors monitor and transmit changes in humidity and temperature to the building control systems. Several models are available for humidity only or for humidity and temperature sensing. The humidity only units are available in either 4 to 20 mA or 0 to 10 Volt signal versions. Combination humidity and temperature units are available in either dual current or voltage versions, transmitting proportional signals back to the controller.
  • Controller Configuration Switch — Allows Users to Adjust Room Comfort and to Choose Occupancy Features That Match the Application and Controller
  • Occupancy Light-Emitting Diode (LED) Indicator — Displays the Current Operating Mode of the Controller (VMA1200 and VMA1400 Series Controllers Only)
  • Manual Override Pushbutton (PB) — Overrides Time-of-Day Scheduling When the Space Is Occupied Outside of Normal Occupied Hours Schedule
The TE-68xx-xN00S Series provides temperature sensing in room wall mount applications. It allows local setpoint temperature adjustment and temporary occupancy override. A warmer/cooler dial is included on certain models for minor temperature adjustments from the setpoint. An occupancy override button allows the user to request a time-of day scheduling override when the space is occupied outside of the normal occupied hours schedule. All sensors have DIP switches that enable or disable unit functions. Depending on the model chosen, the wires connecting the sensor to the controller can be terminated using a screw terminal block or modular jack connection, offering wiring flexibility. All models include a Zone Bus access port for connecting accessories to access the 6-pin modular jack. This feature allows a technician to commission or service the controller via the sensor.

The Facility Explorer One-to-One Wireless Room Sensing System enables RF room sensors to wirelessly communicate to FX-PC Series Programmable Controllers (FX-PCA, FX-PCG, and FX-PCV). This One-to-One Wireless Room Sensing System is the functional equivalent of an NS Series Network Sensor, but it eliminates all the hard wiring between the room sensor and the controller.
The two main components of this system are the FX-WRZ Series Wireless Room Sensor and the FX-WRZ7860-0 Receiver. Depending on the model, the FX-WRZ Series Sensor can transmit sensed temperature, temperature setpoint, sensed humidity, occupancy status, and low battery conditions. FX-WRZ Series Wireless Room Sensor models are available with or without an LCD, and are designed for indoor intra-building applications only.
Several models of FX-WRZ Series Wireless Room Sensors include an onboard passive infrared (PIR) occupancy sensor that detects motion to determine if a space is occupied. This feature provides up to 30% energy savings in high-energy usage environments such as schools, dormitories, offices, and hospitals by adjusting the temperature of the space based on the occupancy status. In addition, the PIR occupancy sensor facilitates trending of floor space usage in these environments.
The FX-WRZ7860-0 Receiver acts as an interface between the FX-WRZ Series Wireless Room Sensors and the FX-PC Series Programmable Controller. The FX-WRZ7860-0 receives the data from the FX-WRZ Series Wireless Sensors, and passes it onto the FX-PC Series Programmable Controller over its Sensor Actuator (SA) Bus.
In a typical application, one FX-WRZ Series Wireless Room Sensor reports to one FX-WRZ7860-0 Receiver; however, you can associate up to five FX-WRZ Series Wireless Room Sensors with a single FX-WRZ7860-0 Receiver. In these multi-sensor applications, the receiver passes all of the room sensors’ data to the FX-PC Series Programmable Controller. You can then configure the FX-PC Series Programmable Controller to either average the room sensors’ temperature and humidity inputs, or select the highest or lowest sensed temperature and humidity for control of the target zone.
