Use the WRZ-STR0000-2 Series Wireless Refrigerator or Freezer Temperature Transmitter and Probe Assemblies to sense the temperature in either a refrigerator or freezer unit, and transmit wireless temperature data to a receiver or controller.

The new WRZ-STR0000-2 Series Wireless Sensors are compatible with the new WRG1830/ZFR183x Pro Series Wireless Field Bus, but also backwards compatible with the WNC1800/ZFR182x Pro Series Wireless Field bus System, the ZFR181x Series Wireless Field bus System, and the WRZ-7860-0 Receiver.

In a mesh application, the WRZ sensor is compatible with the ZFR18xx Wireless Field Bus Systems (ZFR181x, ZFR182x, ZFR183x). See Table 1. The transmitter communicates with system controllers through the ZFR18xx Router, the ZFR or the ZFR Pro Series Router. Up to nine WRZ Series Sensors can associate with a single Controller.

You can also use the WRZ-STR0000-2 Series Wireless Refrigerator or Freezer Temperature Transmitter and Probe Assembly in a one-to-one application non-mesh network to communicate with a WRZ-7860-0 Wireless Receiver. The WRZ-7860-0 Receiver transfers data to the controller through the Sensor Actuator (SA) communication bus. In an application, one WRZ-STR0000-2 Series Transmitter reports to one WRZ-7860-0 Receiver, but up to five WRZ-STR0000-2 Series Transmitters can associate with a single WRZ-7860-0 Receiver.

The WRZ-STR0000-2 Series Transmitter can transmit sensed temperature and low battery conditions to an associated router or receiver. Use the WRZ-STR0000-2 Series Wireless Refrigerator or Freezer Temperature Transmitter and Probe Assemblies for indoor, intra-building applications only.

Refer to the WRZ-STR0000-2 Series Wireless Refrigerator or Freezer Temperature Transmitter and Probe Assemblies Product Bulletin (LIT-12011604) for important product application information.

Important: Use the WRZ-STR0000-2 Series Wireless Refrigerator or Freezer Temperature Transmitter and Probe Assemblies to provide an input to equipment under normal operating conditions. Where failure or malfunction of the transmitter and probe assembly 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 transmitter and probe assembly.
