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.
Features:
Wireless RF Design Enables quick, economical, and low-maintenance installations, which reduce installation and wiring costs.
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, helps locate optimum device positions during installation or relocation, and aids in troubleshooting.
Easy Installation and Relocation Provided by 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 proper room sensor operation.
Optional, Battery-Powered WRZ-SST-120 Wireless System Survey 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 application-based frequency agility, which allows for automatically changing to a different channel to avoid RF interference and missed messages (WRZ-7860 applications).
Onboard PIR Occupancy Sensor Available on Some Models Maximizes up to 30% energy savings in high-energy usage environments, and facilitates trending of floor space.
User-Selectable Default Display for Humidity Models Allows users to choose if they want RH or temperature as the default display.
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 Allow control by Warmer/Cooler (W/C), Scaled Value (SCALE), or System-Configured (CONFIG) adjustments.
