1 WRS-TTx Series Wireless Room Temperature Sensors Installation Instructions WRS-TTP0000-0, WRS-TTR0000-0, WRS-TTS WRS-TTP0000-1, WRS-TTR0000-1, WRS-TTS Issued February ,Rev.HPart No , Rev. H Application The WRS-TTx Series Wireless Room Temperature Sensors are designed to sense room/zone temperature and transmit wireless temperature control data to TE-7800 Series and WRS-RTN Series Receivers. Depending on the sensor model, the WRS-TTx Series Sensors can transmit sensed temperature, setpoint temperature, occupancy status, and low battery conditions to an associated receiver. The associated receiver passes the temperature data on to a supervisory controller or a field controller. Note: WRS-TTx Series Sensors (CE Mark compliant models) have a reduced transmission power (10 dbm) and transmission range to comply with the requirements of select countries. The WRS-TTx Series Sensors are designed for two types of room/zone temperature sensing systems: The One-to-One temperature sensing system provides temperature data for single-zone temperature control based on a sensor reporting to a single TE-7800 Series Receiver. The One-to-One system provides temperature data to Johnson Controls VMA14, AS-AHU, AS-UNT, AS-VAV, DX-9100, and FXxx Series Field Controllers. Refer to the TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT ) for more information. The Many-to-One temperature sensing system provides temperature data for multi-zone control and allows multiple WRS-TTx Series Sensors to report to a single WRS-RTN Series Receiver. Up to 60 sensors can be associated with a single receiver. The practical average due to typical application environments is 10 to 20 sensors per receiver. The WRS-RTN Series Receiver works in conjunction with a Metasys system Network Automation Engine (NAE) or Network Control Engine (NCE) to distribute temperature data to the multiple field controllers on the Metasys network. Refer to the WRS Series Many-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT ) for more information. Refer to the QuickLIT website for the most up-to-date version of this document. The WRS-TTx Series Sensors use direct-sequence, spread-spectrum Radio Frequency (RF) technology and operate on the 2.4 GHz ISM band. The sensor meets the IEEE standard for low power, low duty cycle RF transmitting systems. The WRS-TTx Series Sensors operate as transceivers to create a bidirectional association with the target receiver, which allows the temperature sensing system to confirm and synchronize data transmissions between the sensors and the receiver. The WRS-TTx Series Sensors are designed for indoor, intra-building applications only. IMPORTANT: The WRS-TTx Series Wireless Room Temperature Sensor is 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 WRS-TTx Series Wireless Room Temperature Sensor 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. IMPORTANT: The WRS-TTx Series Sensors are not designed or intended for use in mission-critical or life/safety applications.

2 North American Emissions Compliance United States Compliance Statement (Part 15.19) This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference, and 2. This device must accept any interference received, including interference that may cause undesired operation. Warning (Part 15.21) Changes or modifications not expressly approved by the party responsible for compliance could void the user s authority to operate the equipment. RF Exposure (OET Bulletin 65) To comply with FCC RF exposure requirements for mobile transmitting devices, this transmitter should only be used or installed at locations where there is at least 20 cm separation distance between the antenna and all persons. Canada Industry Canada Statements The term IC before the certification/registration number only signifies that the Industry Canada technical specifications were met. This device has been designed to operate with an antenna having a maximum gain of 2 db. Antenna having a higher gain is strictly prohibited per regulations of Industry Canada. The required antenna impedance is 50 ohms. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the Equivalent Isotropically Radiated Power (EIRP) is not more than that required for successful communication. Le terme «IC» précédant le numéro d'accréditation/ inscription signifie simplement que le produit est conforme aux spécifications techniques d'industry Canada. Cet appareil a été conçu pour fonctionner avec une antenne d'un gain maximum de 2 dbi. En application des réglementations d'industry Canada, l'utilisation d'une antenne de gain supérieur est strictement interdite. L'impédance d'antenne requise est de 50 ohms. Pour réduire les interférences radio potentielles avec les dispositifs d'autres utilisateurs, le type d'antenne et son gain doivent être choisis de façon à ce que la Puissance Isotrope Rayonnée Équivalente (PIRE) ne soit pas supérieure à la puissance nécessaire pour une bonne communication. Installation Follow these guidelines when installing the WRS-TTx Series Sensors: Transport the sensor in the original container to minimize vibration and shock damage. Verify that all the parts shipped with the sensor. Do not drop the sensor or subject it to physical shock. Do not attempt to remove or repair the circuit board from the sensor housing. Except for battery replacement, the sensor has no user-serviceable parts inside. 2

Location Considerations A successful wireless temperature sensing system requires proper location of the sensors and receivers. For information on locating and installing the TE-7800 Series Receivers in One-to-One applications, refer to the TE-7800 Series Receiver for One-to-One Wireless Room Temperature Sensing Systems Installation Instructions (Part No ). FIG:dmnsns For information on installing the WRS-RTN Series Receivers in Many-to-One applications, refer to the WRS-RTN Series Receivers for Many-to-One Wireless Room Temperature Sensing Systems Installation Instructions (Part No ). Note: For detailed information on estimating the number of WRS-RTN Series Receivers needed for a Many-to-One application and locating the receivers for optimum signal coverage, refer to the WRS Series Many-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT ). Temperature Sensor Location Considerations When locating a WRS-TTx Series Sensor, follow the same best practices used to locate a hardwired temperature control, sensor, or thermostat: Mount the sensor on an interior wall where it is easily accessible, at least 54 in. (137 cm) 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. Wireless Sensor Location 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 receiver whenever possible. (Wireless transmissions may pass through floors. Test the signal strength before installing sensors and the associated receiver on different building levels.) Wherever possible, locate the sensor in the direct line-of-sight to the receiver. Avoid metal obstructions (including equipment rooms and elevator shafts) and concrete or brick walls between the receiver and the sensor. Do not locate the sensor in recessed areas or metal enclosures. Do not mount a sensor less than 2 ft (61 cm) from the receiver. 3

4 Wireless RF Signal Transmission Considerations The specified maximum transmission range for indoor line-of-sight transmissions between a WRS-TTx Series Sensor and an associated 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). The specified maximum transmission range for indoor line-of-sight transmissions between a WRS-TTx Series Sensor and an associated 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 165 ft (50 m). Pressing and holding the manual occupancy override button on the WRS-TTx Series Sensor (Figure 1) initiates a signal strength test with the associated receiver. Refer to the TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT ) or the WRS Series Many-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT ) for more information on performing signal strength tests in your application. You can also use the WRS-SST Series Wireless Sensing System Tool to determine the signal strength between the sensor and receiver locations. Refer to the WRS-SST Series Wireless Sensing System Tools Technical Bulletin (Part No ) for more information on testing signal strength in your application. Mounting the Base Using the Factory-Installed, Double-Sided Adhesive Foam Tape The WRS-TTx Series Sensors are surface mounted using the strips of double-sided adhesive foam tape that are factory-installed on the back of the sensor mounting base. To mount the sensor base: 1. Clean the mounting surface to ensure that the factory-installed, double-sided adhesive foam tape sticks to the mounting surface. Note: The mounting surface, sensor mounting base, and ambient temperature must be at least 50 F (10 C) to mount the base using the factory-installed, double-sided adhesive foam tape. 2. Remove the sensor housing from its mounting base (Figure 2). 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. Sensor Housing 3. Swing the sensor housing off the mounting base. 1. Loosen (but do not remove) the tamper-resistant set screw on the locking tab of the mounting base. Mounting Base Tabs 4. Pull the bottom of the sensor housing down and off the tabs on the mounting base. Figure 2: Removing the Sensor Housing from its Mounting Base (Reverse the Steps to Reinstall the Housing) 3. Peel the protective paper off the strips of double-sided adhesive foam tape that are factory-installed on the back of the sensor mounting base. 4. Check that the base is upright (set screw on top) and press the base firmly onto the clean mounting surface. 5. See Preparing the Sensor for Operation. 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 2). 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. FIG:cvr_rmvl 4

5 Note: New double-sided adhesive foam tape is required to remount the base on the surface; use Can-Do National Tape (Code No ) adhesive foam tape or its equivalent. Preparing the Sensor for Operation To prepare the sensor for operation, and to reinstall the sensor housing on its mounting base: 1. Set the sensor address by setting the TRANSMITTER ID and PROPERTY CODE DIP switches on the back of the sensor housing (Figure 3). Note: The sensor address can be set at any time, but the sensor does not operate in a wireless temperature sensing system until the DIP switches are set to the correct positions. Refer to the TE-7800 Series One-to-One Wireless Temperature Sensing System Technical Bulletin (LIT ) or the WRS Series Many-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT ) for information on setting the sensor DIP switches to the correct positions for your temperature sensing application. 2. 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 3). 3. 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 3) 4. Align the tabs on the bottom edge of the sensor 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 2.) 5. Use a 1/16 in (1.6 mm) Allen wrench or Johnson Controls T Allen-Head Adjustment Tool to tighten the tamper-resistant set screw and secure the sensor assembly onto its mounting base (Figure 2). PROPERTY CODE DIP Switch Block TRANSMITTER ID DIP Switch Block Sensor ON/OFF Switch Insert two AA Alkaline Batteries in the battery compartment. Figure 3: Back View of WRS-TTx Series Sensor Housing, Showing Address DIP Switches and Batteries Repair Information If the WRS-TTx Series Sensor fails to operate within its specifications, replace the unit. For a replacement sensor, contact the nearest Johnson Controls representative. The two AA alkaline batteries supplied with the WRS-TTx Series Sensor typically have a life of 5 years or more. The sensor reports a low battery condition to the receiver, which relays the low battery condition to the temperature control system. Replace the sensor batteries with two high-quality AA alkaline batteries as necessary, ensuring that the batteries are installed in the proper polarity. Both batteries should be replaced at the same time. Note: 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.
