WRZ Series Wireless Room Sensors Product Bulletin Applications The WRZ Series Wireless Room Sensors sense room or zone temperature and transmit wireless temperature control data. Some models also sense and transmit relative humidity (RH). Several models include an onboard passive infrared (PIR) occupancy sensor that detects motion to determine the occupancy status of a space. This feature maximizes up to 30% energy savings in high-energy usage environments such as schools, dormitories, offices, and hospitals as it adjusts the temperature of the space based on the occupancy status. In addition, the PIR occupancy sensor facilitates analysis of floor space usage in these environments. In a mesh application, the WRZ sensor is compatible with the ZFR18xx Wireless Field Bus Systems (ZFR181x, ZFR182x, ZFR183x). See Table 4. Depending on the system controller, the transmitter communicates through the ZFR18xx Router (ZFR or ZFR Pro Series Router). Up to nine WRZ Series Sensors can associate with a single Controller. In a ZFR1800 Series Wireless Field Bus System application, the sensors communicate with the Controller through the ZFR18xx Series Router. In wired field bus applications, the sensors communicate with a WRZ-7860 Wireless Receiver. The WRZ-7860 Receiver transfers data to the controller by means of the Sensor Actuator (SA) communication bus. In a typical application, one WRZ Series Sensor reports to one WRZ-7860 Receiver, but up to five WRZ Series Sensors can communicate with a single WRZ-7860 Receiver for multisensor averages or high and low temperature selection. The WRZ Series Wireless Room Sensors include models with either a temperature setpoint dial or the setpoint adjustment push buttons and LCD. Occupants can view the zone temperature, RH, and view and adjust the zone temperature setpoint. Some temperature and humidity models include an RH push button to toggle between temperature and RH on the display. These models also have the capability to set the preferred default display to either temperature or RH. Some models also include a �F and �C button, which provides a choice between degrees Fahrenheit (F) and degrees Celsius (C). Models are available with or without an LCD. Different models of the WRZ Series Sensor can transmit sensed temperature, setpoint temperature, sensed humidity, occupancy status, and low battery conditions to an associated router or receiver. The WRZ Series Sensors are for indoor, intra-building applications only. The WRZ Series Sensors use direct-sequence, spreadspectrum RF technology, and operate on the 2.4 GHz Industrial, Scientific, and Medical (ISM) band. The receiver meets the IEEE 802.15.4 standard for low-power, low-duty cycle RF transmitting systems. LIT-12011653 2021-03-12 Figure 1:WRZ Series Wireless Room Sensors CAUTION: Use the WRZ Series Wireless Room Sensor only to provide an input to equipment under normal operating conditions. Where failure or malfunction of the sensor could lead to personal injury or property damage to the controlled equipment or other property, you must design additional precautions 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 sensor. Important: The WRZ Series Wireless Room Sensor, used in conjunction with a WRZ-7860 Receiver in a One-to-One wireless room sensing system or a ZFR18xx Series Router in a ZFR1800 Series Wireless Field Bus System, is not for use in mission-critical or life and safety applications.

Dimensions Figure 2:WRZ Series Sensor with occupancy sensor and setpoint adjustment buttons, in. (mm) Figure 3:WRZ Series Sensor with occupancy sensor and setpoint adjustment dial, in. (mm) � Integral wireless signal strength testing built into the sensor provides quick and easy visual indication of the wireless RF signal strength between the sensor and its associated receiver. This helps to locate the optimum device positions during installation or relocation, and aids in troubleshooting. � Easy installation and relocation with two mounting options, tape or screws. � Easily applicable data types transmit the sensed zone temperature and humidity, temperature setpoint, and low battery condition to a WRZ-7860 Receiver or ZFR1800 Series Router. � Simple, field-adjustable DIP Switches provide all of the necessary configuration settings for the sensor, simplifying commissioning. � Wireless signal strength and low battery condition mapping provides real-time status for correct room sensor operation. � Optional, battery-powered ZFR-HPSST-0 wireless sensing system tool provides wireless mobility to check for the best RF link, and to determine the optimum receiver mounting locations. � High resistance to RF interference from other radio devices or RF noise sources results from applicationbased frequency agility. This automatically changes to a different channel to avoid RF interference and missed messages for WRZ-7860 applications. � Onboard PIR cccupancy sensor available on some models maximizes up to 30% energy savings in highenergy usage environments, and analyzes floor space usage. � On the user-selectable display for humidity models, users can choose RH or temperature as the default display setting. � Display models provide an intuitive user experience with a full range of WRZ temperature setpoint range options, RH or fan speed, and occupancy status. � Three temperature setpoint range options for control with Warmer/Cooler (W/C), Scaled Value (SCALE), or System-Configured (CONFIG) adjustments. � Blinking red LED light flashes 5 seconds after the application of power to indicate the firmware revision. For example, the LED flashes three times in the startup process to indicate firmware revision 3. Ordering information See Table 1 for a list of available models and accessories for use with the WRZ Series Wireless Room Sensor. See Table 2 for a comparison of available models of the WRZ Series Wireless Room Sensor. Features and benefits � Wireless RF design provides quick, economical, and lowmaintenance installations that reduces installation and wiring costs. 2 WRZ Series Wireless Room Sensors Product Bulletin Table 1: Selection charts Product code number WRZ-MHN0100-2 WRZ-MTJ0100-2 WRZ-RMT10K-2 WRZ-STR0000-2 WRZ-THJ0000-2 WRZ-THN0000-2 WRZ-TTJ0000-2 WRZ-TTK0000-2 WRZ-TTP0000-2 WRZ-TTR0000-2 WRZ-TTS0000-2 ZFR-HPSST-0 T-4000-119 Description Wireless Room Temperature and Humidity Sensor with Passive Infrared (PIR) occupancy sensor, battery level and signal strength LED, manual occupancy override button, without display, ZFR183x compatible Wireless Room Temperature Sensor with PIR occupancy sensor, display, setpoint button adjustment for Warmer/Cooler (+/-) setpoint adjustment or scaled setpoint adjustment: 55�F to 85�F (13�C to 29�C), and manual occupancy override button, ZFR183x compatible Wireless Room Temperature Sensor for Remote 10K Temperature Probes, display, �F/�C button, and manual occupancy override button, ZFR183x compatible Wireless Room Temperature Sensor with Remote 3K Refrigerator or Freezer Temperature Probe, display, �F/�C button, and manual occupancy override button, ZFR183x compatible Wireless Room Temperature or Humidity Sensor with display, setpoint adjustment buttons for Warmer/Cooler (+/-) setpoint adjustment or scaled setpoint adjustment: 55�F to 85�F (13�C to 29�C), �F/�C button, RH button, and manual occupancy override button, ZFR183x compatible Wireless Room Temperature and Humidity Sensor with battery level or signal strength LED and manual occupancy override button, ZFR183x compatible Wireless Room Temperature Sensor with display, setpoint adjustment buttons for Warmer/Cooler (+/-) setpoint adjustment or scaled setpoint adjustment: 55�F to 85�F (13�C to 29�C), �F/�C button, and manual occupancy override button, ZFR183x compatible Wireless Room Temperature Sensor with display, setpoint adjustment buttons for Warmer/Cooler (+/-) setpoint adjustment or scaled setpoint adjustment: 55�F to 85�F (13�C to 29�C), �F/�C button, fan speed control button, and manual occupancy override button, ZFR183x compatible Wireless Room Temperature Sensor with Warmer/Cooler (+/-) setpoint dial adjustment, battery level or signal strength LED, and manual occupancy override button, ZFR183x compatible Wireless Room Temperature Sensor with battery level or signal strength LED, manual occupancy override button, and no setpoint dial adjustment, ZFR183x compatible Wireless Room Temperature Sensor with setpoint dial adjustment scale: 55�F to 85�F (13�C to 29�C), battery level or signal strength LED, and manual occupancy override button, ZFR183x compatible Wireless Sensing System Tool is a lightweight, portable, wireless transmitter/receiver designed to serve as an RF signal tester or site survey tool prior to installation of a ZFR18xx Series Wireless Field Bus System Allen-head adjustment tool: 1/16 in.
