Description 

The WRZ Series Wireless Room Sensors are designed to 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 if a space is occupied. This feature maximizes 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. In a ZFR1800 Series Wireless Field Bus System application, the sensors communicate with FAC26 Series, FEC16 Series, FEC26 Series, and VMA16 Series Controllers by means of 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 be associated with a single WRZ-7860 Receiver for multi-sensor averaging or high/low temperature selection.

The WRZ Series Wireless Room Sensors include models with either a temperature setpoint dial or the setpoint adjustment pushbuttons 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 %RH pushbutton 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. Some models also include a °F/°C button, which provides a choice between degrees Fahrenheit (F) and degrees Celsius (C). Models are available with or without an LCD. Depending on the sensor model, 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 designed for indoor, intra-building applications only. The WRZ Series Sensors use direct-sequence, spread-spectrum 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.
