Application
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.
In a mesh application, the WRZ sensor is compatible with the ZFR18xx Wireless Field Bus Systems
(ZFR181x, ZFR182x, ZFR183x). See Table 3. 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 a 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.
Important: The WRZ-STR0000-2 Series Wireless Refrigerator or Freezer Temperature
Transmitter and Probe Assemblies are intended 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, additional precautions must be designed 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.
Important: Le WRZ-STR0000-2 Series Wireless Refrigerator or Freezer Temperature
Transmitter and Probe Assemblies est destiné à transmettre des données entrantes à un
équipement dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un
dysfonctionnement du transmitter and probe assembly risque de provoquer des blessures
ou d'endommager l'équipement contrôlé ou un autre équipement, la conception du système
de contrôle doit intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à
intégrer de façon permanente d'autres dispositifs, tels que des systèmes de supervision ou
d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement
ou de protection en cas de défaillance ou de dysfonctionnement du transmitter and probe
assembly.

- Page 6 Figure 3. Important: Do not turn on the WRZ-STR0000-2 Series Transmitter until an installed receiver or controller operates in the same Radio Frequency (RF) range. Without this condition, the transmitter uses a higher-than-normal battery current as it attempts to find a receiver or controller within range, which results in reduced battery life.
