Johnson Controls WRZ Series Installation Manual

Application
Use the WRZ Series Wireless Room Sensors to sense room
and zone temperature and transmit wireless temperature
control data. Some models also sense and transmit
relative humidity (RH).
In a mesh application, the WRZ sensor is compatible
with the ZFR18xx Wireless Field Bus Systems (ZFR181x,
ZFR182x, ZFR183x). See Table 3. Depending on the system
controller, the transmitter communicates through the
ZFR18xx Router (ZFR or ZFR Pro Series Router). Up to nine
WRZ Series Sensors can associate with a single Controller.
In wired Field Bus applications, the sensors communicate
with a WRZ-7860 Wireless Receiver. The WRZ-7860 Receiver
transfers data to the controller through the Sensor
Actuator (SA) communication bus. In a typical application,
one WRZ Series Sensor reports to one WRZ-7860 Receiver,
but up to five WRZ Series Sensors can associate with a
single WRZ-7860 Receiver for multi-sensor averaging or
high and low temperature selection.
WRZ Series sensor models are available with or without
an LCD. Depending on the sensor model, the WRZ Series
Sensor can transmit sensed temperature, setpoint
temperature, sensed humidity, occupancy status, and low
battery conditions to an associated router or receiver.
The WRZ Series Sensors are for indoor,intra-building
applications only.
The WRZ Sensors use direct-sequence, spread-spectrum
radio frequency (RF) technology, and operate 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.
Important: The WRZ Series Sensors are intended
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.
WRZ Series Wireless Room Sensors Installation
Important: Le WRZ Series Sensors 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.
