The FX-WRZ Handheld Temperature Room Sensor is designed to sense the temperature of a room or zone and transmit wireless temperature control data.

In a Mesh Network Wireless Field Bus System application, the sensors communicate with the FX-PC Controllers by means of the FX-ZFR18xx (FX-ZFR or FX-ZFR Pro Series) Router.

In a one-to-one wireless room sensing application, the sensor communicates with an FX-WRZ78xx Wireless Receiver. The FX-WRZ78xx Receiver transfers data to the controller by means of the Sensor Actuator (SA) communication bus. In a typical application, one FX-WRZ Series Sensor reports to one FX-WRZ78xx Receiver, but up to five FX-WRZ Series Sensors can be associated with a single FX-WRZ78xx Receiver for multi-sensor averaging for high and low temperature selection.

The FX-WRZ Handheld Temperature Room Sensor comes with an LCD. The FX-WRZ Sensor can transmit sensed temperature, setpoint temperature, occupancy status, and low battery conditions to an associated router or receiver. The FX-WRZ Series Sensor is designed for indoor, intra-building applications only.

The FX-WRZ Sensor uses direct-sequence, spread-spectrum RF technology, and operates 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.

  • Risk of Personal Injury and Property Damage
  • Use the FX-WRZ Sensor only to provide an input to equipment under normal operating conditions. Where failure or malfunction of the sensor 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 sensor.
  • Risque de blessure et dégâts matériels.
  • Le FX-WRZ Sensor est destiné à transmettre des données entrantes à un équipement dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du sensor 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 sensor.
