Application
The 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 a mesh application, the WRZ sensor is compatible with both the ZFR1810 and ZFR1820 Pro Series Wireless
Field Bus Systems. The transmitter communicates with FAC26 Series, FEC16 Series, FEC26 Series, and
VMA16 Series Controllers through the ZFR18xx Router (ZFR or ZFR Pro Series Router). Up to nine WRZ Series
Sensors can be associated 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 by means of 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 be associated with a single WRZ-7860 Receiver for multi-sensor averaging or high/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 designed for indoor,
intra-building applications only.
The WRZ Sensors use 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.
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.

Mounting
The WRZ Series Sensors can be surface mounted using the adhesive tape pieces affixed to the back of the
sensors.
Location Considerations
Temperature Sensor Considerations
When locating a WRZ Series Sensor, follow the same best practices used to locate a hard-wired temperature
control, sensor, or thermostat:
• Mount the sensor on an interior wall where it is easily accessible, at least 1.4 m (55 in.) above the floor, in an
area where the temperature is representative of the entire controlled space.
• Avoid enclosed or recessed locations and locations behind curtains, doors, or other obstructions to the
controlled space.
• Avoid locations near entry foyers, doors, windows, supply air ducts, and pipes.
• Avoid locations that are exposed to drafts, direct sunlight, and other sources of heat or cooling.
• Avoid locations where the sensor could be exposed to excessive vibration.
Wireless Transmission Considerations
In addition to the typical thermostat and temperature control location considerations, follow these guidelines for
locating a sensor in wireless applications:
• Locate the sensor on the same building level as the nearest ZFR or ZFR Pro Series Router, or
WRZ-7860 Receiver.
• For best signal transmission, locate the sensor at least 51 mm (2 in.) away from any metal obstructions.
• Wherever possible, locate the sensor in the direct line of sight to the ZFR or ZFR Pro Series Router, or
WRZ-7860 Receiver. Signal transmission is best if the path between the sensor and the router or receiver is as
direct as possible. Line of sight is desirable but not required, as long as the path is not blocked by large metal
objects.
• Avoid metal obstructions (including equipment rooms and elevator shafts) and concrete or brick walls between
the sensor and the ZFR or ZFR Pro Series Router, or WRZ-7860 Receiver.
• Do not locate the sensor in recessed areas or metal enclosures.
• In mesh network applications, install the sensors within range of two or more ZFR or ZFR Pro Series Routers.
Redundancy in the layout provides the best reliability in wireless installations.
• Do not mount the sensor closer than 0.61 m (2 ft) or farther than 30 m (100 ft) from the ZFR or ZFR
Pro Series Router, or 45 m (150 ft) from the WRZ-7860 Receiver.
• The recommended indoor line-of-sight transmission range between the sensor and the ZFR or ZFR Pro Series
Router is 15 m (50 ft).
Installing the WRZ Series Sensor
The WRZ Series Sensor can be surface mounted using the double-sided adhesive foam tape factory installed on
the back of the device. To mount the sensor base with adhesive foam tape:
1. Clean the mounting surface to ensure that the adhesive foam tape sticks to the surface.
Note: The mounting surface, mounting base, and ambient temperature must be at least 10C (50F) when
mounting the sensor base with adhesive foam tape.

WRZ Series Wireless Room Sensors Installation Instructions

2. Remove the sensor housing from its mounting base as shown in the following figure.
3. Peel off the protective paper from one side of the factory-installed strips of adhesive foam tape on the back of
the mounting base.
4. When positioned correctly, the arrow between the terminal slots on the inside of the mounting base should
point up. Ensure that the mounting base is upright (tamper-resistant set screw on top) and press the base
firmly onto the clean mounting surface.
5. See Preparing the WRZ Series Sensor for Operation.
IMPORTANT: Do not power up the WRZ Series Sensor until a receiver or controller is installed and operating
within the same Radio Frequency (RF) range. If this condition is not met, the sensor uses a higher-than-normal
battery current as it attempts to find a receiver or controller within range, resulting in reduced battery life.
During normal operation, the WRZ Series Sensor is typically in a suspended sleep mode to conserve battery life.
The sensor periodically wakes up, reads its sensor values, and sends the sensor data to the associated
controller. The wake-up time varies, depending on the sensor type and changes in value. Adjusting the setpoint
dial or pressing the manual occupancy override button causes the sensor to wake up immediately and send its
data.
IMPORTANT: During start up and commissioning or in a power-outage situation, the associated controller may
be shut down for extended periods of time. To further conserve on battery life, the WRZ Series Sensor adjusts its
rejoin attempt time to much longer periods (6 times every 2 minutes for the first 10 minutes, then once every 30
minutes for 72 hours, and then once per day thereafter). This may cause the sensor to be offline to the system
until it rejoins. Adjusting the setpoint or pressing the manual occupancy override button causes the sensor to
wake up and begin its normal update sequence.

Removing a Mounting Base Installed with Double-Sided Adhesive Foam Tape
To remove or relocate a sensor mounted with double-sided adhesive foam tape:
1. Remove the sensor housing from its mounting base (Figure 3).
2. Remove the mounting base from the mounting surface by carefully twisting the base off of the surface.
3. Remove the adhesive foam tape from the mounting base and clean the mounting base to remove any leftover
adhesive.
Note: New double-sided adhesive foam tape is required to remount the base on the surface; use Can-Do National
Tape (Code No. 99116) adhesive foam tape or its equivalent.
Preparing the WRZ Series Sensor for Operation
To prepare the WRZ Series Sensor for operation, and to reinstall the sensor housing on its mounting base:
1. Place the appropriate DIP switch overlay (based on the application) over the DIP switches. See the following
figures.

c. Set the SENSOR# to 199 for applications with only one sensor per controller. Use the other settings for
additional sensors in applications with a single controller performing temperature averaging or high/low
selection within a zone. Refer to the WRZ Series One-to-One Wireless Room Sensing System Technical
Bulletin (LIT-12011641) for information on commissioning multiple WRZ Series Sensors in a WRZ Series
One-to-One Wireless Room Sensing System.
d. Set the AREA switches to match the AREA switch on the WRZ-7860 Receiver.
e. Set the Transmitter ID switches to match the Transmitter ID on the WRZ-7860 Receiver.
3. Install two AA alkaline batteries (supplied) into the battery compartment on the back of the sensor. Ensure that
the batteries are installed in the proper polarity (Figure 6).
4. If the address DIP switches are set to the correct positions and the temperature sensing system is ready for
operation or testing, set the POWER DIP switch to the ON position (Figure 4 or Figure 5).
Five seconds after the power is applied, the red LED flashes to indicate the firmware revision. For example,
firmware revision 3 is indicated by the LED flashing three times during the startup process.
5. Align the tabs on the bottom edge of the mounting base with the slots on the bottom edge of the sensor
housing, and rotate the sensor assembly onto its mounting base. (Reverse the procedure shown in Figure 3.)
6. Use a 1.6 mm (1/16 in.) Allen wrench or Johnson Controls T-4000-119 Allen-Head Adjustment Tool to tighten
the tamper-resistant set screw and secure the sensor assembly onto its mounting base (Figure 3).
Testing Signal Strength
Once the WRZ sensor is communicating with the ZFR or ZFR Pro Series Router, or WRZ-7860 Receiver, press
and release the manual occupancy override button to display signal strength.
Press and hold the manual occupancy override button on the WRZ Series Sensor (Figure 1) for 5 seconds or more
to place the sensor into Rapid Transmit Mode and initiate a signal strength test with the associated ZFR or ZFR Pro

On LCD models, the signal strength is shown on the display on the face of the sensor (callout in the following
figure).
Note: For WRZ Series Sensors with an LCD display, the humidity value may appear as 0.0% when the sensor is
joining a network. This condition is transitory and does not transfer to the Building Automation System (BAS).
An optional WRZ-SST-120 Wireless Sensing System Tool can also be used with any WRZ Series Sensor prior to
installation as a site survey tool, to determine potential locations for system devices and to determine the wireless
signal strength between the system devices in the application.
Refer to the WRZ-SST-120 Wireless Sensing System Tool Installation Instructions (Part No. 24-10563-71) for more
information on testing signal strength. For additional location consideration details, also refer to the following
documents:
• ZFR1800 Series Wireless Field Bus System Technical Bulletin (LIT-12011295)
• WRZ Series One-to-One Wireless Room Sensing System Technical Bulletin (LIT-12011641)
Rapid Transmit Mode
Rapid Transmit Mode forces wireless transmissions between the sensor and the parent ZFR or ZFR Pro Series
Router, or WRZ-7860 Receiver, and indicates wireless signal strength between the devices.
Temperature Setpoint Adjustment/Occupancy Override
Depending on the model, you can use either the large setpoint adjustment dial or the setpoint adjustment buttons
on the face of the network sensor to change the controller mode from unoccupied to occupied, or to adjust the
temperature setpoint.
To change the occupancy using the dial, rotate the dial slightly, so the backlight on the LCD lights up. If you rotate
the dial slightly again, and the controller is in the unoccupied mode, the controller changes from the
after-normal-working-hours setback mode to the normal-working-hours comfort mode. Alternatively, you can use
the pushbuttons to change the controller mode from unoccupied to occupied.
To adjust the setpoint using the dial, continue rotating the dial until the current setpoint is displayed and flashing.
Turn the dial clockwise to increase the setpoint and counterclockwise to decrease the setpoint. Stop turning the dial
once the preferred setpoint is reached. The new setpoint stops flashing and becomes fixed after a few seconds. To
use the pushbuttons instead, press the up arrow button to increase the setpoint or the down arrow to decrease it.

°F/°C Temperature Mode Selection
All models include a °F/°C pushbutton on the face of the network sensor to provide temperature scale options for
display. Pressing the pushbutton toggles the temperature mode between Fahrenheit and Celsius on the LCD to
force the WRZ Series Sensor into rapid transmit mode:
1. Press and hold the manual occupancy override (Occ) button on a WRZ Series Sensor for 5 or more seconds.
In rapid transmit mode, the sensor transmits once every 10 seconds for 5 minutes, for a total of 30 update
messages. After each transmission, the sensor’s occupancy LED flashes to indicate the wireless signal
strength between the sensor and the associated parent ZFR or ZFR Pro Series Router.
2. In addition, when a sensor is in rapid transmit mode, the target ZFR or ZFR Pro Series Router’s LED blinks to
indicate the received signal strength:
3. If there is a poor signal or no signal, determine why the signal strength between the sensor and router is not
adequate for your application.
4. If there is a good or average signal, the sensor and router are communicating.
Use the sensor’s rapid transmit mode in conjunction with the WRZ-SST-120 Wireless Sensing System Tool to
perform a site survey and test the wireless signal strength between potential device locations, and adjust ZFR or
ZFR Pro Series device locations before installing the devices. For more information on using the sensor’s rapid
transmit mode with the tool, refer to the WRZ-SST-120 Wireless Sensing System Tool Installation Instructions (Part
No. 24-10563-71).
Manual Occupancy Override Button
Pressing the manual occupancy override button, located on the left side of the sensor, serves two main functions.
First, it temporarily sets the space to an occupied state. Second, it checks the wireless signal strength of the
sensor. The LED on the sensor flashes 3 times to indicate a strong signal, 2 times to indicate a good signal, or 1
time to indicate a marginal signal. For sensors with an LCD display, a number of bars on the display indicates
wireless signal strength (3 bars for a strong signal, 2 bars for a good signal, or 1 bar for a marginal signal).
Commissioning Multiple WRZ Sensors
Mesh Mode
You can add up to nine WRZ Series Sensors per FEC, FAC, VMA16 Controller, or VMA8132 Controller in the mesh
mode.
The Zone DIP switches on the WRZ Sensor relate to the Zone Netsensor (SA Bus device) address configured for
the sensor in the Controller Configuration Tool (CCT). For example, if you set the Zone DIP switches to a value of 3
(that is, DIP switch 1 and 2 are set to ON), you must use Zone Netsensor address 202 in the CCT. You can add up
to nine WRZ Sensors per field controller. You can use any nine of the sixteen available Zone Netsensor address
settings at a time.
The mesh mode of operation is intended for use with the ZFR or ZFR Pro Series Coordinator and ZFR or ZFR
Pro Series Router. Table 2 describes the Zone DIP switch settings for the wireless applications in mesh mode.

One-to-One Mode
You can add up to five WRZ Series Sensors per WRZ-7860 receiver in the One-to-One mode.
The one-to-one mode of operation is intended for use with the WRZ-7860 Receiver. For one-to-one mode,
Figure 5 shows DIP switch settings.
Repair Information
If the WRZ Series Wireless Room Sensor fails to operate within its specifications, replace the unit. For a
replacement sensor, contact the nearest Johnson Controls representative.
Batteries
The two AA alkaline batteries supplied with the WRZ Series Sensor typically have alife of 4 years or more. The
sensor reports a low battery condition to the receiver or controller, which relays the low battery condition to the
Metasys® system.
Battery strength can also be checked at the WRZ Series Sensor by pressing and holding the manual occupancy
override button (Figure 1). If the battery level and signal strength LED at the sensor is on while pressing and
holding the button, the battery power is acceptable. If the LED is off while pressing and holding the button, the
battery power is low and the batteries need to be replaced.
On LCD models, the low battery condition is shown by Lo bAt flashing in the display on the face of the sensor.
Note: When replacing batteries, replace both batteries at the same time. Batteries removed from this device must
be recycled or disposed of in accordance with local, national, and regional regulations. Only certified technicians or
qualified building maintenance personnel should service Johnson Controls® products. Lithium batteries with a
maximum cell voltage of 1.5 volts can be substituted to extend the period between battery replacement. Do not mix
lithium and alkaline batteries in this device.
