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 RFAddress 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.


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.

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 SensorsThe 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.

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.

The WRS-TTx Series Sensors also provide manual occupancy override and signal strength diagnostic capabilities. See Table 2 for the available WRS-TTx Series Sensor models.

Note: The WRS-TTx0000-0 Series Sensors have a 15 dBm transmission power, and the WRS-TTx0000-1 Series Sensors (CE Mark compliant models) have a reduced transmission power (10 dBm) and transmission range to comply with the requirements of select countries.

WRS-TTx Series Wireless Room Temperature Sensors are also designed for use in 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.

TE-7820 Series ReceiversThe TE-7820 Series Receivers (Figure 3) are designed to receive wireless data messages from WRS-TTx Series Sensors and communicate that data via a hard-wired connection to a Johnson Controls VMA14 Series Field Controller.

The TE-7820 Series Receiver collects wireless data transmissions containing the sensed zone temperature, the zone temperature setpoint, the zone occupancy status, signal strength measurements, and sensor low-battery conditions from one to four associated WRS-TTx Series Wireless Sensors. The receiver then processes the zone data and delivers that data directly to a single VMA14 Series Controller via a hard-wired zone bus interface.

The TE-7820 Series Receiver requires 24 VAC, Class 2 supply power. The receiver has an 8-pin RJ-45 port for the zone bus interface with the VMA14 Series Controller, two Light-Emitting Diodes (LEDs) that indicate RF signal and zone bus status, and two DIP switch blocks for setting the RF address and sensor input mode (Figure 3).

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 and low sensor battery conditions, and two DIP switch blocks for setting the RF address and sensor input mode (Figure 4).

RF Interference and Security in One-to-One ApplicationsThe 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:

• 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.


• 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 ApplicationsTo 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 RFAddress 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.


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 SelectionOne 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.

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.

Guidelines for Job Sites with 510 or More TE-7800 Series ReceiversYou 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:

- 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 OverviewThere 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 WorkflowThe 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).


• 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 RFAddresses on page 35 for more information.

Setting the TE-7800 Series Receiver RF AddressThe 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 RFAddresses on page 35 for more information.

Setting the WRS-TTx Series Sensor RF AddressAssociate 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. 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.)

4. Match the receiver RF address by setting the numbered switches on the TRANSMITTER ID DIP switch block to the same positions as the numbered switches on the RF ADDRESS DIP switch block on the associated receiver (Figure 7).

5. Ensure the batteries are installed correctly and move the sensor POWER switch to the ON position (if you are putting the sensor into operation).

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 ApplicationsUp 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.

- 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 ControllersThe 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.

Connecting the TE-7820 Receiver to VMA14 Series Controllers

To connect the power and zone bus between the TE-7820 Series Receiver and the VMA14 Series Controller using the 6 ft (1.8 m) interface cable provided, see Figure 8 and follow these instructions:

1. Connect the interface cable between the Tstat modular socket on the side of the VMA14 Series Controller and the ZONE BUS to VMA1400 (Tstat) modular socket on the receiver (Figure 8).

Note: Additional zone bus interface cables, with lengths up to 100 ft (30.5 m), are available. See the TE-7800 Series One-to-One Wireless Room Temperature Sensing System Product Bulletin (LIT-12011096) for zone bus interface cable ordering information.


2. Connect the power cable between the 24 VAC spade terminal connections on the side of the VMA14 Series Controller and the 24 VAC spade terminal connections on the receiver (Figure 8).

Note: One end of the spade terminal connector portion of the interface cable features two Y-spade terminal connectors that tap into the 24 VAC power source provided by the VMA14 Series Controller. The other end of the spade terminal connector portion of the interface cable features a removable screw terminal block that is pushed onto the 24 VAC spade terminal connectors on the receiver.

Note: If a WRS-TTR0000-x Series Sensor is used in the installation, the orange wire should be insulated, taped back, and not connected at the controller end, since there is no setpoint adjustment available on this sensor model.

• Connect the brown wire to the analog input common.

3. Connect the three-position screw terminal block with the blue, yellow, and green wires to the three spade terminal connections on the receiver labeled:

a. OCCUPANCY RELAY

b. LOW BATTERY RELAY

c. RELAY COMMON

Note: Position the screw terminal block so that the three screw heads are facing outward (Figure 9).

4. Connect the other end of the interface cable with the spade terminal connectors to the appropriate Binary Input (BI) terminations on the controller. If the 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.

7. Connect the green wire to the controller as follows:

• For AS-AHU Series Controllers, connect the green wire to BICM or BI COM (24 VAC common).

• For AS-UNT100 Series Controllers, connect the green wire to 24 VAC.


• For AS-UNT1100 Series Controllers, connect the green wire to BI SRC (24 VAC).

• For AS-VAV100 Series Controllers, connect the green wire to BINARY COM (24 VAC common).

• For DX-9100 Series Controllers, connect the green wire to DI COM (24 VAC common).

• For FXxx Series Controllers, connect the green wire to terminal D01 & D02 COM.

8. Connect the two-position screw terminal block containing the red and black wires to the two spade terminal connections on the receiver identified as 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 ApplicationsVMA14 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.


Configuring VMA14 Series Controllers for One-to-One ApplicationsThe 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


8. Select the appropriate occupancy mode for the sensor (Figure 11).

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.

Calculating TE-7830 Series Receiver Analog Output Signal ValuesThe 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 should use the values provided in those procedures to configure the zone temperature and zone setpoint ranges for these controllers.

Temperature Values for 0 to 5 VDC Analog Signal Applications

The 0 to 5 VDC analog signals from the TE-7830 Series Receiver are scaled to zone temperature and zone setpoint values as illustrated in the scales in Figure 12. Use these scaled values in the sections that follow to configure the analog inputs of the AS-AHU, AS-UNT, AS-VAV, or DX-9100 Controller.

The scaled values in Figure 12 provide the proper linearization for the specific controller selected for the installation. The setpoint adjustment dial can be adjusted from 55 to 85°F or 13 to 29°C on the WRS-TTS0000-x Series Sensor, or it can be adjusted for warmer/cooler (+/-) on the WRS-TTP0000-x Series Sensor.

Note: The Zone Setpoint Scale shown in Figure 12 is for -5 to 5° setpoint range applications.

Temperature Values for 0 to 10 VDC Analog Signal Applications

The TE-7830 Series Receiver’s 0 to 5 VDC analog output signal can be applied to certain controllers that accept only 0 to 10 VDC analog signals. Use the following information to configure controllers that accept only 0 to 10 VDC signals.

Note: The calculations and values are the same if the field controller is set up for °F or °C.

In warmer/cooler applications, the range of adjustment can be changed to match the requirements of the application. Table 4 includes setpoint values calculated using the following equations:

• Setpoint at 0 V = Lower Setpoint – (0.5 x K)

• Setpoint at 10 V = Upper Setpoint + (6.5 x K)

where:

Note: In the procedures that follow, the warmer/cooler setpoint adjustment range is assumed to be ±5 (F° or C°).

Configuring AS-AHU, AS-UNT, and AS-VAV Controllers for One-to-One Applications

AS-AHU, AS-UNT, and AS-VAV Controllers are easily configured using the HVAC PRO software tool. HVAC PRO software 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.

Commissioning AS-AHU, AS-UNT, or AS-VAV Controllers for One-to-One Applications

AS-AHU, AS-UNT, and AS-VAV Controllers are easily commissioned using the HVAC PRO software tool (Release 8.04B or later).

For AS-UNT and AS-VAV Controllers, do not remove Jumper J1 (identified in Figure 2 on the TE-7830 Series Receiver). With Jumper J1 not removed, occupancy override status is enabled via the zone temperature. Set the AS-UNT or AS-VAV analog input switches for 0 to 10 VDC.

For AS-AHU Controllers, set the analog input switches for voltage and remove Jumper J1.

To ensure proper operation of the TE-7830 Series Receiver and the AS-AHU, AS-UNT, or AS-VAV Controller, verify the following features (if chosen):

1. Validate communication from the zone sensor to the controller as follows:

a. Monitor the zone setpoint analog input and rotate the setpoint adjustment dial the entire range.

Note: For multiple sensor installations, move the adjustment dials to low end of the setpoint range on all of the sensors. Test each sensor individually by moving the adjustment dial on each sensor (one at a time) through the entire range to verify the response to that sensor. Remember to return the dial to the low end of the setpoint range before testing the next sensor.

You can wait for a sensor to report the adjustment to the receiver or simply press the occupancy override button to initiate an immediate sensor transmission to the receiver.

b. Press the manual occupancy override button and verify that the Temp Occ status momentarily becomes Closed.

Note: For multiple sensor applications, repeat Steps 1a and 1b for each sensor.

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 StrengthYou 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.
