A simple One-to-One wireless room temperature sensing system consists of one to
four WRS-TTx Series Wireless Room Temperature Sensors communicating
single-zone temperature data to an associated TE-7820 Series or TE-7830 Series
Receiver (Figure 1).

TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
Note: Multiple WRS-TTx Series Sensor models, TE-7800 Series Receiver
models, and WRS-SST Series Wireless Sensing System Tools are
available. The WRS-TTx0000-0 Series Sensors, TE-78x0-0 Series
Receivers, and WRS-SST-100 Tool have a 15 dBm transmission power.
The WRS-TTx0000-1 Series Sensors, TE-78x0-1 Series Receivers, and
WRS-SST-101 Tool (CE Mark compliant models) have reduced
transmission power (10 dBm) and transmission range to comply with the
requirements of select countries.
The receiver meets the IEEE 802.15.4 standard for low power, low duty cycle
RF transmitting systems and operates on the 2.4 GHz Industrial, Scientific,
Medical (ISM) band. The One-to-One wireless room temperature sensing system
is designed for indoor applications only, and should not be used for outdoor or
inter-building applications.
The WRS-TTx Series Sensors and the TE-7800 Series Receivers operate as
transceivers to create a bidirectional association between the sensors and the
receivers that allows the temperature sensing system to synchronize and confirm
data transmissions between the devices. The sensors and receivers must be located
and installed properly to provide adequate RF signal strength to maintain this
wireless association.
The maximum transmission range for indoor line-of-sight transmissions between a
WRS-TTx0000-0 Series Sensor and an associated TE-78x0-0 Series Receiver is
500 ft (152 m). Taking into consideration RF signal absorption and reflection due
to metal obstructions, walls, and furniture found in typical building interiors, the
practical average indoor line-of-sight transmission range between a sensor and
receiver is 200 ft (61 m). See Related Documentation for references to installation
instructions.
The maximum transmission range for indoor line-of-sight transmissions between a
WRS-TTx0000-1 Series Sensor and an associated TE-78x0-1 Series Receiver is
375 ft (114 m). Taking into consideration RF signal absorption and reflection due
to metal obstructions, walls, and furniture found in typical building interiors, the
practical average indoor line-of-sight transmission range between a sensor and
receiver is 164 ft (50 m). See Related Documentation for references to installation
instructions.
The sensors and receivers are associated with each other with unique
RF addresses. The RF addresses are established on the devices by setting the
switches on address DIP switch blocks on the devices. After the sensor/receiver
associations are created, the sensors transmit (at 60 second intervals) the sensed
zone temperature, the setpoint temperature, zone occupancy status, and low battery
conditions, depending on the WRS-TTx Series Sensor model, the target controller
model, and the controller configuration. See Radio Frequency Addresses for
One-to-One Applications on page 11, Setting the TE-7800 Series Receiver
RF Address on page 16, and Setting the WRS-TTx Series Sensor RF Address on
page 18 for more information on setting RF addresses in One-to-One sensing
system applications.
TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
5
In One-to-One applications with two to four sensors, the target receiver can be
configured to send temperature control data based on the average temperature, the
highest temperature, or the lowest temperature sensed by the WRS-TTx Series
Sensors. See Sensor Averaging and High or Low Temperature Selection on page 12.
The WRS-TTx Series Sensors and the TE-7800 Series Receivers also provide
signal strength indication and other wireless diagnostic data.
IMPORTANT: The One-to-One wireless room temperature sensing system,
TE-7800 Series Receivers, and WRS-TTx Series Sensors are not designed or
intended for use in mission-critical or life/safety applications.
Note: WRS-TTx Series Sensors and TE-7800 Series Receivers are not
compatible with TE-7700 Series Sensors and Receivers. TE-7700 Series
Sensors and Receivers are discontinued, and replacements are no longer
available for order. If a TE-7700 Series Sensor or Receiver fails in a
TE-7700 Wireless Sensing System application, you must replace the
TE-7700 Series Receiver with a TE-7800 Series Receiver and replace the
associated TE-7700 Sensors with WRS-TTx Series Sensors.
WRS-TTx Series Wireless Room Temperature Sensors
The WRS-TTx Series Wireless Room Temperature Sensors (Figure 2) are
designed to sense room/zone temperature and transmit wireless temperature and
zone status data to TE-7800 Series Receivers.
Depending on the sensor model, the WRS-TTx Series Sensors can transmit the
sensed temperature, setpoint temperature, occupancy status, and low battery
conditions to an associated receiver. The receiver passes the temperature data to a
controller.

WRS Series Many-to-One Wireless Room Temperature Sensing Systems. Refer to
the WRS Series Many-to-One Wireless Room Temperature Sensing System
Technical Bulletin (LIT-12011095) for more information.
Note: Do not attempt to set up a WRS-TTx Series Sensor to report to more than
one TE-7800 Series Receiver. One-to-One wireless sensing system
applications do not support global sharing of a sensor’s data. Attempting to
set a single sensor to report to multiple receivers typically results in
controller malfunctions and loss of temperature control in the zones.

The TE-7830 Series Receiver requires 24 VAC, Class 2 supply power. The
receiver has removable terminal blocks for wiring the analog interface with
supported controllers, two Light-Emitting Diodes (LEDs) that indicate RF signal

RF Interference and Security in One-to-One Applications
The WRS-TTx Series Sensors, TE-7800 Series Receivers, and the One-to-One
wireless sensing system are designed to virtually eliminate RF interference with
other wireless applications. In most commercial environments, the One-to-One
system does not encounter or generate significant RF interference, even in
environments that are saturated with cell phones and competing Wireless Fidelity
(WiFi) applications.
The WRS-TTx Series Sensors and TE-7800 Series Receivers operate on the
2.4 GHz ISM band and use multi-frequency Direct-Sequence, Spread-Spectrum
(DSSS) technology.
Cell phones do not operate on the 2.4 GHz ISM band, and cell phone interference
is not a problem with One-to-One systems, except when a cell phone is operated
within 3 ft (1 m) of a WRS-TTx Series Receiver. When One-to-One systems
encounter most other WiFi transmissions in the 2.4 GHz ISM band, the
transmissions appear as merely noise and do not significantly impact wireless
sensing system communication.
Using DSSS technology, the WRS-TTx Series Sensor is designed to transmit a
rapid sequence of high-speed (2 millisecond) redundant data bursts to the
associated receiver every 60 seconds. The sensor transmits up to eight redundant
data bursts in rapid sequence, each burst is transmitted on a different Zigbee™
frequency. When a single data burst is successful received and acknowledged (or if
all eight redundant transmissions fail), the sensor goes dormant for 60 seconds and
then repeats the transmission burst sequence.
These multi-frequency, redundant, data-transmission sequences greatly enhance
the success of the wireless sensing system data transmissions. Transmitting short,
high-speed data bursts at 60-second intervals also reduces RF data-transmission
collisions and interference with other WiFi transmissions. The DSSS technology
also prevents most malicious RF interference.
RF interference and transmission failures can also be prevented by maintaining an
adequate distance between RF transmitting devices. Some examples include:
10
•
WRS-TTx Series Sensor should not be mounted less than 3 ft (1 m) from a
TE-7800 Series Receiver.
•
Cell phones should not be used within 3 ft (1 m) of a WRS-TTx Series
Receiver.
•
WiFi access points should be mounted at least 20 ft (6 m) from any
WRS-TTx Series Sensor or TE-7800 Series Receiver.
TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
•
Other low-power WiFi transmitting devices should be mounted at least
3 ft (1 m) from any WRS-TTx Series Sensor or TE-7800 Series Receiver.
•
WiFi devices that transmit powerful signals should be mounted at least
20 ft (6 m) from any WRS-TTx Series Sensor or TE-7800 Series Receiver.
•
2.4 GHz cordless phones and some older phone headsets can cause
interference and should not be used anywhere near a One-to-One sensing
system.
To secure One-to-One RF wireless messages, the WRS-TTx Series Sensors and
TE-7800 Series Receivers use a custom Johnson Controls message protocol that
prevents deciphering any One-to-One data transmissions that are received or
intercepted by any other WiFi devices.
Radio Frequency Addresses for One-to-One Applications
To establish wireless RF associations in One-to-One applications, you must assign
and configure the same, unique RF address on the TE-7800 Series Receiver and
the WRS-TTx Series Sensor or sensors associated with that receiver.
The RF address for a TE-7800 Series Receiver is configured manually by
positioning the numbered switches on the RF ADDRESS DIP switch block on the
receiver. The address setup procedure is the same for TE-7820 and TE-7830 Series
Receivers. See Setting the TE-7800 Series Receiver RF Address on page 16.
The RF address for each WRS-TTx Series Sensor associated with a TE-7800
Series Receiver must match the receiver RF address. The WRS-TTx Series
Sensor’s RF address is configured by positioning the numbered switches on the
TRANSMITTER ID DIP switch block on the sensor. See Setting the
WRS-TTx Series Sensor RF Address.
The RF ADDRESS DIP switch block on the receiver and the TRANSMITTER
ID DIP switch block on the sensor are binary switch blocks. The switches on each
switch block are assigned numbers (1, 2, 4, 8, 16, 32, 64, 128, and 256). The
RF address is a number between 1 and 511, equal to the sum of the numbers of the
switches that are in the ON position. Thus placing Switches 1, 4, 8, and 32 in the
ON position establishes an RF address of 45 for the device.
The One-to-One wireless sensing system does not use the PROPERTY CODE
DIP switch block. Set all switches on the PROPERTY CODE DIP switch block
to OFF on all WRS sensors in One-to-One applications. The PROPERTY CODE
DIP switch block is used in Many-to-One wireless sensing systems applications.
Refer to the WRS Series Many-to-One Wireless Room Temperature Sensing
System Technical Bulletin (LIT-12011095) for more information.
TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
11
In multiple-sensor applications, two or more WRS-TTx Series Sensors have the
same RF address and the TE-7800 Series Receiver identifies individual sensors by
their serial numbers (which is embedded in the sensor’s RF transmissions). In the
single sensor applications, the receiver associates with the first WRS-TTx Series
Sensor with a matching RF address and rejects all others. If 15 minutes pass with
no RF transmission from the associated sensor, the receiver attempts to associate
with another matching sensor (if one has been received) or waits for the first
matching RF transmission.
If the TE-7800 Series Receiver fails to respond to a WRS-TTx Series Sensor with
a matching RF address, the receiver may have already locked onto another sensor
with the same RF address. To clear the receiver from an incorrect association,
cycle the receiver power off and back on, or momentarily change the receiver’s
RF address to a different RF address and then back to the original RF address
again.
Never use the same RF address for two receivers that are in the same building or
general location unless there are 510 or more receivers at the job site and you have
thoroughly tested the duplicate address applications’ signal strengths to ensure that
the receivers are well out of the RF signal range of each other’s associated sensors.
RF signals can reflect off objects or pass through glass windows, and it is possible
for RF signals to travel between buildings or reach receivers several floors away.
Installations with 510 or more TE-7800 Series Receivers require special
consideration. For large installations, contact a Johnson Controls representative for
application support. See Guidelines for Job Sites with 510 or More TE-7800 Series
Receivers for more information.
Sensor Averaging and High or Low Temperature Selection
One to four WRS-TTx Series Sensors can be associated with a TE-7800 Series
Receiver in a One-to-One sensing system application.
In One-to-One applications with one WRS-TTx Series Sensor, the single sensor
transmits the sensed temperature, setpoint temperature, occupancy status, and
low-battery conditions to the receiver.
In One-to-One applications where two to four WRS-TTx Series Sensors are
associated with a single receiver, you can choose one of three sensor input modes:
•
Temperature Averaging (AVG): The receiver averages the temperature
inputs from all of the associated sensors and uses the average as a single
control temperature for the temperature control loop.
•
High Temperature Selection (HIGH): The receiver uses the highest sensed
temperature as the control temperature for the temperature control loop.
•
Low Temperature Selection (LOW): The receiver uses the lowest sensed
temperature as the control temperature for the temperature control loop.
In multiple sensor applications, the receiver must be set to one of the sensor input
modes using the MULT XMTRS DIP switch block on the receiver. See Setting the
WRS-TTx Series Sensor RF Address for detailed procedures.
12
TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
If more than one of the switches on the MULT XMTRS DIP switch block are
positioned ON, the AVG switch takes priority over the HIGH and LOW switches,
and the HIGH switch takes priority over the LOW switch.
In a multiple sensor application, all of the sensor addresses must match the
associated TE-7800 Series Receiver RF address. The receiver identifies the
individual sensors by the unique serial number that is programmed into each
sensor and sent with each data message from the sensor.
Note: In single-sensor and multiple-sensor applications, a One-to-One sensing
system interfaces with only one supported controller.

Only the UNT11xx Series has enough binary inputs to support low-battery indication in One-to-One applications.
The user must define a sideloop with the appropriate ranging to use the TE-7830 Series Receiver for this
application.
Guidelines for Job Sites with 510 or More TE-7800 Series Receivers
You can create up to 509 unique RF address settings for One-to-One applications
at a job site. Job sites that have 510 or more TE-7800 Series Receivers require
duplicate RF address settings. Duplicate RF address settings can create random
interference and erratic operation in One-to-One applications. Observe the
following guidelines when installing 510 or more receivers at a job site:
•
Ensure that One-to-One applications with duplicate RF address setting are
located as far from each other as possible to avoid RF signal overlap and
conflicts between the applications.
•
Typically, the One-to-One applications with duplicate addresses are out of
range of each other if the individual applications are:
•
14
-
two or more floors or building levels apart and not near windows on the
same side of the building or near atriums or other open common areas
-
more than 1,000 ft (300 m) away from each other
Test for and verify the absence of RF signal overlap between One-to-One
applications with duplicate RF address settings.

Detailed Procedures
One-to-One System Commissioning Overview
There are a variety of procedures that must be performed to design, install,
commission, configure, and troubleshoot a One-to-One wireless room temperature
sensing system. Many of these procedures are contained in this section of this
document. Some of the required procedures are presented in other documentation.
•
See the Related Documentation table for references to the documents with
information on locating and installing WRS-TTx Series Sensors and
TE-7800 Series Receivers.
•
Refer to the supported controller’s documentation for information on
installing, commissioning, configuring, and troubleshooting the target
controller.
Commissioning Procedures Requirements
To commission a One-to-One wireless temperature sensing application, you need:
•
one to four WRS-TTx Series Sensors
•
one TE-7820 Series or TE-7830 Series Receiver
•
a 24 VAC Class 2 power supply for the receiver
•
an installed, commissioned, and configured VMA14 Series or supported
controller
•
a zone bus interface cable for TE-7820 Series Receiver (VMA14 Series
Controller) applications or an analog interface cable for TE-7830 Series
Receiver (supported digital controller) applications
Note: A 9 ft (2.8 m) interface cable is included with each TE-7800 Series
Receiver. Additional cable lengths are available for TE-7820 Series
Receiver/zone bus applications. You can fabricate longer cables for
TE-7830 Series Receiver/analog interface applications. Refer to the
TE-7800 Series Receivers for One-to-One Wireless Room Temperature
Sensing System Installation Instructions (Part No. 24-10139-8) for
more information on cables and cable length limitations.
Commissioning Procedures Workflow
The procedures required to commission and configure a One-to-One system can be
performed in a variety of sequences. The job site and workflow dictate the order in
which these procedures are performed. The procedure order shown below is a
typical sequence.
To commission and configure a One-to-One system, you must perform the
following procedures:
•
Install, commission, and configure the target field controller.
•
Install and address the WRS-TTx Series Sensor(s).
TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
15
•
Commission/address and install the TE-7800 Series Receiver.
•
Test the RF signal strength between the associated devices.
•
Connect the TE-7800 Series Receiver to the target controller.
•
Test and confirm operation of the complete One-to-One application.
Planning and Record-Keeping
When commissioning and configuring a control system with several One-to-One
systems and multiple sensors, receivers, and controllers, we strongly recommend
that you obtain a set of the building plans, the Heating, Ventilating, and Air
Conditioning (HVAC) plans, and the building specifications.
Use the building plans and specifications to determine the best line-of-sight
RF pathways and the potential locations for the sensors and receivers. Test the
potential device locations to determine if the RF signal strength is adequate and
adjust device locations as necessary.
You should create a sensor/receiver association table to record all of the device
addresses and a device map that shows the locations of all sensors, receivers, and
supported field controllers for the final as-built control system.
Note: Do not create duplicate RF addresses on any of the receivers at your job
site. Duplicate RF addresses can cause a variety of problems in One-to-One
applications. If your job site has 510 or more receivers, you must take
special precautions to avoid RF signal conflicts between One-to-One
applications with the same address. See Guidelines for Job Sites with 510
or More TE-7800 Series Receivers on page 14 and Testing for RF Signal
Conflicts at Job Sites with Duplicate RF Addresses on page 35 for more
information.
Setting the TE-7800 Series Receiver RF Address
The TE-7800 Series Receiver requires a unique RF address to communicate with
associated WRS-TTx Series Sensors. Set the RF address for the receiver by
positioning the numbered switches on the RF ADDRESS DIP switch block. See
Radio Frequency Addresses for One-to-One Applications for more information.
To manually set the TE-7800 Series Receiver RF address:
1. Disconnect power to the TE-7800 Series Receiver.
2. Set the numbered switches on the RF ADDRESS DIP switch block to the
desired RF address (Figure 5).

Note: The TE-7800 Series Receivers ship from the factory with all DIP switches
set in the OFF position. When the DIP switches are all set in the OFF
position (address 0) or all set in the ON position (address 511), the
TE-7820 Series Receiver automatically uses the N2 network address
assigned to the connected VMA14 Series Controller for its RF address. If
your application uses an automatically assigned RF address, you must
determine the TE-7820 Series Receiver’s RF address and set the
RF address on the associated WRS Series Sensor or sensors to match the
receiver’s assigned RF address.
Do not use the 510 RF address setting for a permanent receiver address.
Reserve the 510 RF address setting for testing and troubleshooting
One-to-One applications.
3. Check the TRANSMITTER ID DIP switch block on the back of the
associated sensor and make certain that the POWER switch is set in the OFF
position (Figure 7). See Setting the WRS-TTx Series Sensor RF Address for
more information.
4. Apply 24 VAC power to the TE-7800 Series Receiver.
5. Repeat this procedure for each receiver in your application.
Note: Do not create duplicate addresses on any of the receivers at your job site.
Duplicate addresses can cause a variety of problems in One-to-One
applications. If your job site has more than 509 receivers, you have to take
special precautions to avoid RF signal conflicts between applications with
the same address. See Guidelines for Job Sites with 510 or More TE-7800
Series Receivers on page 14 and Testing for RF Signal Conflicts at Job
Sites with Duplicate RF Addresses on page 35 for more information.
TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
17
Setting the WRS-TTx Series Sensor RF Address
Associate the WRS Series Sensors to a TE-7800 Series Receiver by setting the
TRANSMITTER ID DIP switches on the sensors to the same positions as the
RF ADDRESS DIP switches on the target TE-7800 Series Receiver so that the
RF address setting on both devices match. See Radio Frequency Addresses for
One-to-One Applications for more information.
If more than one sensor is used in your One-to-One application, the RF address
(TRANSMITTER ID) for each sensor must match the RF address
(RF ADDRESS) for the associated TE-7800 Series Receiver. The receiver
identifies the individual sensors by their serial numbers, which are sent with each
sensor transmission.
To set the WRS-TTx Series Sensor RF address (TRANSMITTER ID):
1. Remove the WRS-TTx Series Sensor housing from the sensor mounting base
as shown in Figure 6.
2. Insert a coin into the slot
on the top of the sensor
housing, and depress the
locking tab on the mounting
base to release the housing.
1. Loosen (but do not remove)
the tamper-resistant set screw
on the locking tab of the
mounting base.
3. Swing the
sensor housing off
the mounting base.

2. Move the WRS-TTx Series Sensor power switch on the TRANSMITTER ID
DIP switch block to the OFF position (Figure 7).
3. Set all of the switches on the PROPERTY CODE DIP switch block to the
OFF position (Figure 7). (One-to-One sensing system applications do not use
PROPERTY CODE settings for their RF addresses. PROPERTY CODE
settings are used in Many-to-One sensing system applications only.)

6. Reinstall the sensor housing to the wall mount base.
7. If the associated receiver is configured and powered on, you can press the
sensor occupancy button to determine if the sensor and receiver are
communicating.
Setting the Sensor Input Mode for Multiple Sensor Applications
Up to four WRS-TTx Series Sensors can be associated with a single
TE-7800 Series Receiver. In multiple-sensor One-to-One applications, you must
select a sensor input mode for the application by setting the switches on the
MULT XMTERS DIP switch block. See Sensor Averaging and High or Low
Temperature Selection for more information.
In multiple sensor applications requiring setpoint adjustment, the setpoints of each
sensor are averaged. If only one sensor is to control the setpoint, the other sensors
should not include setpoint adjustment capability.
To set the sensor input mode on a TE-7800 Series Receiver for multiple sensor
applications:
1. Set the MULT XMTRS DIP switches on the receiver to the required positions.
•
In single-sensor applications, set all three MULT XMTRS DIP switches to
the OFF position.
•
In multiple-sensor applications, set the MULT XMTRS DIP switches
according to the desired application input mode.
TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
19
-
If the sensor temperature readings are averaged, set only the AVG
DIP switch to the ON position.
-
If the highest sensor temperature reading is used, set only the HIGH
DIP switch to the ON position.
-
If the lowest sensor temperature reading is used, set only the LOW
DIP switch to the ON position.
Note: In multiple-sensor applications requiring setpoint adjustment, the setpoints
of each sensor are averaged. If only one sensor is to control the setpoint, the
other sensors should not include setpoint adjustment capability.
If more than one of the switches on the MULT XMTRS DIP switch block
are positioned ON, the AVG switch takes priority over the HIGH and
LOW switches, and the HIGH switch takes priority over the LOW switch.
In single-sensor and multiple-sensor One-to-One applications, the
TE-7800 Series Receiver interfaces with only one supported controller.
Connecting TE-7800 Series Receivers to Supported Controllers
The TE-7820 Series Receiver connects to VMA14 Series Controllers only
(Figure 8). The TE-7830 Series Receiver connects to Johnson Controls AS-AHU,
AS-UNT, AS-VAV, DX-9100, and FXxx Series Field Controllers (Figure 9).
Note: The TE-7800 Series Receivers are sensitive RF devices. To avoid
degrading this sensitivity, do not run the interface cable near high voltage
power wiring, phase controlled lighting, and/or phase controlled electric
motors.

controller does not accommodate 1/4 in. (6 mm) spade terminal connectors, the
wire ends should be clipped and stripped before making the connections.
5. Connect the blue wire to the occupancy binary input of the controller. In
applications where a binary input is not used for this function, the blue wire
should be insulated, taped back, and not connected at the controller end.
Note: Remove jumper J1 in AS-AHU, DX-9100, and FXxx Series
applications to prevent the zone temperature from being driven low if
the manual occupancy override button on the WRS-TTx Series Sensor
is pressed. AS-AHU, DX-9100, and FXxx Series Controllers do not use
the occupancy override option. See Figure 9 for J1 jumper location.
Note: Install jumper J1 in AS-UNT and AS-VAV applications to allow the
receiver to drive the zone temperature low if the manual occupancy
override button on the WRS-TTx Series Sensor is pressed. AS-UNT
and AS-VAV Controllers do not require a separate binary input for
occupancy status, since these controllers detect occupancy override
when the zone temperature signal goes to 0 V. See Figure 9 for
J1 jumper location.
6. Connect the yellow wire to the low-battery binary input terminal on the
controller. In applications where a binary input is not available for low-battery
conditions, the yellow wire should be insulated, taped back, but not connected
at the controller end.

24 VAC and 24 VAC COMMON.
Note: Position the terminal block so that the screw heads are facing outward
(Figure 9).
9. Connect the other end of the interface cable with the two Y-spade terminal
connectors to the appropriate 24 VAC terminations on the controller. If the
controller does not accommodate 6 mm (1/4 in.) spade terminal connectors,
clip and strip the wire ends before making the connections.
Configuring Supported Controllers for One-to-One Applications
VMA14 Series Controllers and supported digital field controllers must be properly
configured to operate with TE-7800 Series Receivers and One-to-One sensing
system applications.
You must use the HVAC PRO software tool (Release 8.04B or later) to configure
the VMA14, AS-AHU, AS-UNT, and AS-VAV Series Controllers.
You must use the GX-9100 Commissioning Tool (Release 8.04 or later) to
configure the DX-9100 Controllers.
You must use FX Builder to configure the FXxx Series Controllers; refer to the
FX Builder literature for more details.
Note: It is assumed that the user of this document has a working knowledge of
and experience with the HVAC PRO software tool and GX-9100
Commissioning Tool. See Related Documentation on page 3 for references
to relevant Johnson Controls user documentation.
The procedures that follow describe how to configure only those values in
the controller UI that are required for a One-to-One application to interface
and operate with VMA14, AS-AHU, AS-UNT, AS-VAV, or DX-9100
Series Controllers. Refer to the controller documentation and the relevant
software tool documentation for complete information on configuring the
controller.

TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
Configuring VMA14 Series Controllers for One-to-One Applications
The VMA14 Series Controller is easily configured using the HVAC PRO software
tool. HVAC PRO is part of the M-Tool suite of tools. The software also runs on a
Metasys® Operator Workstation (OWS) connected to the N2 Bus to configure,
download, and commission the controller.
You configure the VMA14 Series Controller using HVAC PRO software (Release
8.04B or later) by answering a series of yes/no and multiple choice questions,
specifying setpoints and other parameters. HVAC PRO software has a library of
applications, control sequences, and algorithms that automatically configure the
controller in response to the answers.
To commission the VMA14 Series Controller:
1. Launch the HVAC PRO software tool.
2. On the File menu, click New.
3. Select Application Group: VAV Applications.
4. Select Applications: VMA Single Duct.
5. Click OK.
6. Answer the questions, up to Thermostat Type.
7. Select the appropriate RF wireless sensor option (Figure 10).
Figure 10: Choosing the RF Wireless Sensor Option
TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
25
8. Select the appropriate occupancy mode for the sensor (Figure 11).
Figure 11: Choosing the Occupancy Mode
Note: The third selection for occupancy mode is not recommended since the
WRS-TTx Series Sensor LED does not indicate an occupancy mode.
9. Complete the question/answer session. The thermostat type and occupancy
button are the only two questions relevant to wireless One-to-One applications.
10. Click the Parameters button.
11. Scroll down in the Parameters list box to the RF wireless thermostat
parameter group. Powerfail Diag is TRUE when the RF wireless battery
should be replaced. Read the PRN file to determine the point location (look
under the VAV Box - RF Wireless Thermost heading), when mapping the
point to a supervisory system.
AI 1 Zone Temp and AI 2 (either Remote Adjust or Remote Set Point) are
configurable similar to other VMA single duct applications; however, these
two inputs are fixed at AI 1 and AI 2 when selecting an RF Wireless
Thermostat in the VMASingle Duct application. Zero is the default offset for
the Zone Temperature.
12. Save the application for a VMA14 Series Controller, then download and
commission.
Note: The receiver reports to the control system that the zone temperature and
setpoint are out of range if an RF transmission is not received from its
associated sensor for a period of 15 minutes or more.

TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin
Calculating TE-7830 Series Receiver Analog Output Signal Values
The TE-7830 Series Receiver generates and sends analog signals (0 to 5 VDC) to
the target field controller based on data messages from the WRS-TTx Series
Sensors. The field controller interprets these analog signals to determine the
sensed zone temperature and the zone setpoint.
The configuration procedures in this document provide the values required to
configure the zone temperature range and the zone setpoint range for AS-AHU,
AS-UNT, AS-VAV, and DX-9100 Controllers. In most application scenarios, you

Testing for RF Signal Conflicts at Job Sites with Duplicate
RF Addresses
Job sites with 510 or more TE-7800 Series Receivers require duplicate
RF addresses on some of the receivers and sensors. See Guidelines for Job Sites
with 510 or More TE-7800 Series Receivers on page 14 for more information on
locating receivers and sensors at job sites with duplicate RF addresses.
After you have determined the locations for the receivers and sensors with
duplicate RF addresses, you should test the RF communication between the
devices and ensure there are no RF conflicts between the applications with
duplicate RF addresses before permanently mounting the sensors and receivers.
To test for RF signal conflicts at job sites with duplicate RF addresses:
1. Set the RF addresses on the receivers that have duplicate addresses
(Receiver A and Receiver B) to the test RF address setting of 510, temporarily
position the receivers at their intended locations, and then power only
Receiver A on.
Note: You can monitor WRS-TTx Series Sensors and TE-7800 Series
Receivers in One-to-One wireless sensing systems via a wireless
connection using the WRS-SST Series Wireless Sensing System Tools.
Refer to the WRS-SST Series Wireless Sensing System Tools Technical
Bulletin (Part No. 24-10139-16) for more information on using the
WRS-SST Series Tool to monitor One-to-One applications over a
wireless connection.
2. Create a temporary, movable test sensor by setting the RF address (on the
TRANSMITTER ID DIP switch) to 510 on an unmounted WRS-TTx Series
Sensor and power the sensor on.
3. Temporarily locate the test sensor at the intended location for Sensor A (that
associates with Receiver A), and press the manual occupancy override button
to ensure that the test sensor does communicate with Receiver A.
Note: If Receiver A associates with more than one sensor, repeat Step 3 for
each Sensor A location to ensure that all of the A sensors do
communicate with Receiver A.
4. Next, temporarily locate the test sensor at the intended location for Sensor B
(that associates with Receiver B) and press the manual occupancy override
button to ensure that the test sensor does not communicate with Receiver A.
Note: If Receiver B associates with more than one sensor, repeat Step 4 for
each Sensor B location to ensure that all of the B sensors do not
communicate with Receiver A.
5. Power Receiver A off and power Receiver B on. Repeat the procedures above
to test both the A and B sensor locations and ensure that the:
•
B sensors do communicate with Receiver B
•
A sensors do not communicate with Receiver B

Troubleshooting
Checking a One-to-One Application’s RF Signal Strength
You should verify adequate RF signal strength between sensors and receivers,
especially in applications with excessive distances or metal barriers (such as
ductwork, concrete with metal reinforcements, equipment rooms, or elevator
shafts). The RF signal strength in One-to-One wireless sensing system applications
can be checked ahead of time as follows:
1. Set the DIP switches on the sensor and receiver (or the wireless sensing system
tool) to the same RF address. Make sure that the switches on the PROPERTY
CODE DIP switch block on the sensor are all set to the OFF position.
2. Provide temporary 24 VAC power to the TE-7800 Series Receiver and hold the
receiver in the desired mounting location. (As an alternative, use the optional
battery-powered WRS-SST Series Wireless Sensing System Tools).
3. Hold the WRS-TTx Series Sensor near its desired mounting location in the
zone, with the battery installed and the power switch set to ON.
4. Observe the Wireless LED on the receiver. Approximately every 60 seconds,
an RF transmission occurs and the LED blinks. You can force the sensor into
Rapid Transmit Mode by pressing the WRS-TTx Series Sensor’s manual
occupancy override button for 3 seconds or more.
In Rapid Transmit Mode, the sensor transmits a signal every 10 seconds for
30 minutes. After each transmission, the occupancy override LED on the
sensor flashes (one, two, or three times) on to indicate the signal strength
between the sensor and the receiver. Also, the signal strength LED on the
receiver blinks off to indicate the relative signal strength between the sensor
and receiver.
•
Three consecutive flashes (of the sensor LED) or blinks (of the receiver
LED) every 10 seconds indicate an excellent signal strength.
•
Two consecutive flashes (of the sensor LED) or blinks (of the receiver
LED) every 10 seconds indicate a good signal strength.
•
One flash (of the sensor LED) or blink (of the receiver LED) every
10 seconds indicates a weak signal strength. A weak signal strength may
result in sporadic loss of data; therefore, reconsider the sensor and/or
receiver mounting locations.
If relocating the sensor fails to improve the RF signal reception at the receiver, try
rotating the antenna in 45-degree increments, selecting a different mounting plane
where at least 2 in. (102 mm) of the antenna are below metal structures, or
selecting a new mounting location.
Note: The TE-7820 Series Receiver may be wired up to 300 ft (91 m) from a
VMA14 Series Controller, and the TE-7830 Series Receiver may be wired
up to 100 ft (30 m) from a supported Johnson Controls controller.
