WRZ-STR0000-2 Johnson Controls Wireless Room Sensor

Overview

The Johnson Controls WRZ-STR0000-2 is a wireless room temperature sensor and transmitter assembly designed to measure temperatures in refrigerator or freezer units and transmit data to a compatible wireless receiver or controller. It simplifies installation and reduces labor costs by eliminating the need for dedicated sensor wiring runs in both new construction and retrofit applications.

Features

• Wireless data transmission eliminates the need for hardwired sensor installations.
• Supports both one-to-one wireless non-mesh networks and wireless mesh network communications.
• Features an LCD that indicates the real-time status of the environment.
• Equipped with a Fahrenheit/Celsius button to toggle display temperature units.
• Includes an acrylic-encased temperature sensor probe that acts as a buffer to prevent false temperature spikes when the door is opened.

Specifications

• Power Requirements: 3 VDC supplied by two 1.5 VDC AA alkaline batteries, with a typical life of 5 years or more.
• RF Band: 2.4 GHz ISM Band.
• Temperature Sensor Type: External 3k ohm NTC thermistor probe.
• Refrigerator/Freezer Narrow Range Accuracy: Plus or minus 0.9 degrees Fahrenheit (plus or minus 0.5 degrees Celsius) over the range of -9 to 41 degrees Fahrenheit (-23 to 5 degrees Celsius).
• Transmission Range: Up to 100 feet practical average indoor line-of-sight for mesh applications.

Applications

• Continuous electronic temperature monitoring in commercial refrigerator and freezer units.
• Commercial and light commercial HVAC zoning and building automation systems.
• Multi-zone temperature monitoring in office, retail, and institutional facilities.
• Retrofit upgrades where running new sensor wire is impractical or costly.
