Johnson Controls WRZ Series Installation Manual

Application
Use the occupancy sensing WRZ Series Wireless Room
Sensors to sense room or zone temperature and transmit
wireless temperature control data. The WRZ-MHN0100-2
model also senses and transmits relative humidity (RH).
All models include an onboard passive infrared (PIR)
occupancy sensor that detects motion to determine
the occupancy status of a space. This feature can help
provide up to 30% in energy savings in high-energy usage
environments such as schools, residence halls, offices,
and hospitals because it adjusts the temperature of the
space based on the occupancy status. In addition, the PIR
occupancy sensor facilitates trending of floor space usage
in these environments.
In ZFR18xx Wireless Field Bus Systems (ZFR181x, ZFR182x,
and ZFR183x) mesh applications, up to nine WRZ sensors
communicate with a single controller through the ZFR18xx
Router or ZFR Pro Series Router for multi-sensor averaging
or high and low temperature selection.
In wired Field Bus applications, the sensors communicate
over wireless through the WRZ-7860 Wireless Receiver.
The WRZ-7860 Receiver transfers data to the controller
through the Sensor Actuator (SA) communication bus.
In an application, one occupancy sensing WRZ Series
Sensor reports to one WRZ-7860 Receiver, but up to five
occupancy sensing WRZ Series Sensors can associate with
a single WRZ-7860 Receiver formulti-sensor averaging or
high and low temperature selection.
Models are available with or without an LCD. Depending
on the sensor model, the occupancy sensing WRZ
Series Sensor transmits sensed temperature, setpoint
temperature, sensed humidity, occupancy status, and low
battery conditions to an associated router or receiver. Use
the occupancy sensing WRZ Series Sensors for indoor,
intra-building applications only.
The occupancy sensing WRZ Series 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 IEEE 802.15.4 standard for
low power, low duty cycle RF transmitting systems.

Sensors Installation Guide
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.
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.
