Temperature and Relative Humidity
FX-WRZ Series Wireless Room Sensors
Installation Instructions
Application
The Temperature and Relative Humidity FX-WRZ Series Wireless Room Sensors are designed to
sense room/zone temperature and transmit wireless temperature control data. Some models also
sense and transmit relative humidity.
In an FX-ZFR Series Wireless Field Bus System application, the sensors communicate with the FX-PC
Controllers through the FX-ZFR18xx Series Router.
In a One-to-One Wireless Room Sensing application, the sensors communicate with an FX-WRZ7860
Wireless Receiver. The FX-WRZ7860 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-WRZ7860 Receiver, but up to five FX-WRZ Series Sensors can be associated with a single FX-
WRZ7860 Receiver for multi-sensor averaging or high/low temperature selection.
FX-WRZ Series sensor models are available with or without an LCD. Depending on the sensor
model, the FX-WRZ Series Sensor can transmit sensed temperature, setpoint temperature, sensed
humidity, and low battery conditions to an associated router or receiver. The FX-WRZ Series Sensors
are designed for indoor, intra-building applications only.
The FX-WRZ Sensors use direct-sequence, spread-spectrum RF technology, and operate on the
2.4 GHz Industrial, Scientific, and Medical (ISM) band. The receiver meets the Institute of Electrical
and Electronics Engineers (IEEE) 802.15.4 standard for low power, low duty cycle RF transmitting
systems.
Important:
Use the FX-WRZ Series Sensors only to provide an input to equipment under normal oper-
ating 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 super-
visory or alarm systems or safety or limit controls, intended to warn of or protect against fail-
ure or malfunction of the sensor.
