Installation Instructions WRS-TTx Series Issue Date June 13, 2005 © 2005 Johnson Controls, Inc. 1 Part No. 24-xxxx-xx, Rev. - www.johnsoncontrols.com WRS-TTx Series Radio Frequency (RF) Wireless Transmitters Applications The WRS-TTx Series Wireless Room Temperature Transmitters are designed to report temperature and set point (certain models) to a suitable JCI data receiver. They can be used in two separate types of control systems, depending on the application. FCC and Industry Canada Compliance 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. To comply with FCC’s RF exposure limits for general population / uncontrolled exposure, the antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Industry Canada Statement The term “IC” before the certification/registration number only signifies that the Industry Canada technical specifications were met. Locating the Transmitters The wireless design of the WRS-TTx transmitter allows a great deal of location flexibility without worrying about installing wiring. It is important to follow the standard guidelines for Sensor/Thermostat location so that the sensor is sensing the true room temperature. It is important to avoid outside walls, windows, and areas where sunshine can fall directly on the sensor or where drafts from HVAC equipment are likely. Additionally, it is important to remember that the transmissions used by the WRS-TTx are basically line-of-site and you should review the likely path of the RF energy before installation. Generally it is important to avoid having large areas of metal such as elevators, duct work, or equipment rooms between the sensor and the receiver. An optional signal strength site survey tool receiver is available to determine the appropriate location of the WRS Wireless Room Temperature Sensing System prior to its installation. Using any standard WRS-TTx transmitter in the rapid transmit mode (previously described in the section Occupancy Button and LED), along with the survey tool receiver TE-7820-100, you can verify that the RF transmission signal is sufficient to ensure proper system operation. See Table 1 and refer to the TE-7820-100 RF Wireless Signal Strength Site Survey Tool Product Bulletin (LIT-xxxxxxxx) for more details. Installation Observe the following guidelines and see the Mounting section in this document. • Transport the WRS-TTx in the original container to minimize vibration and shock damage to the WRS-TTx. • Verify that all parts are shipped with the WRS-TTx. • Do not drop the WRS-TTx or subject it to physical shock. • Other than the mounting base, do not open the WRS-TTx. The WRS-TTx has no user-serviceable parts inside. Parts Included • one Wireless Transmitter • two expandable wall anchors and two No. 8 pan-head, self-tapping screws • three strips of double-sided adhesive foam tape • one set of Installation Instructions • two AA alkaline batteries
2 WRS-TTx Series Radio Frequency (RF) Wireless Transmitters Installation Instructions Tools Needed • screwdriver for mounting screws • 1/16 in. (2mm) Allen-head adjustment tool for small screw that secures transmitter to mounting base • small straight blade screwdriver or coin for unsnapping transmitter from base Set up/Commissioning Ensuring the batteries are installed and setting the DIP switches appropriately are the only actions required after mounting/installation. IMPORTANT: Before specifying the WRS Series RF Wireless Room Temperature Sensing System for plenum applications, verify acceptance of exposed plastic materials in plenum areas with the local building authority. Building codes for plenum requirements vary by location. Some local building authorities accept compliance to UL 1995, Heating and Cooling Equipment, while others use different acceptance criteria. IMPORTANT: Use this WRS Series RF Wireless Room Temperature Sensing System only to provide an input to equipment under normal operating conditions. Where failure or malfunction of the sensing system 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 sensing system.

The preferred mounting method for the transmitter uses the two expandable wall anchors included with the unit. Double-sided adhesive foam tape is also provided with each transmitter for installations where building retention and its historical preservation are important, or in buildings featuring marble, granite, glass, mirrored, wood veneer, or other decorative surfaces. Transmitter Location Considerations Consider the following guidelines when selecting a mounting location for the WRS-TTx Series RF Wireless Temperature and Set Point Transmitter: • Locate the transmitter so that it is easily accessible. • Locate the transmitter on the same floor. (Mounting one floor above or one floor below the receiver may work, but will dramatically reduce the RF signal range.) • Locate the transmitter on an inside wall away from water pipes and air ducts, minimally 54 in. (1.4 m) above the floor level, in an area that accurately represents the temperature of the controlled space. • If possible, locate the transmitter in the line of sight with the receiver, to minimize signal transmission loss. • Check that there are no metal objects (including equipment rooms and elevator shafts) blocking the RF transmission signal from the transmitter to the receiver. • Do not mount the transmitter in recessed areas, in shelving units or metal enclosures, or behind curtains or doors. • Do not mount the transmitter in areas that are exposed to direct sunlight or condensation, or in areas that are in close proximity to various heat sources. • Do not mount the transmitter in areas susceptible to warm or cool drafts such as lobbies, walkways, or near a bank of computers. • Do not mount the transmitter less than 2 ft (0.6 m) from the receiver. • The distance between two or more transmitter mounting locations is irrelevant. Removing the Transmitter from its Mounting Base The WRS-TTx Series Transmitter ships from the factory pre-assembled to its mounting base. In order to secure the assembly to a surface, the transmitter must first be removed from its mounting base (as illustrated in Figure 2). Diagram of Sensor Transmitter Cover and Base Figure 2: Removing the Transmitter from its Mounting Base
4 WRS-TTx Series Radio Frequency (RF) Wireless Transmitters Installation Instructions Surface Mounting the Transmitter Using Two Expandable Wall Anchors and Two No. 8 Pan-Head, Self-Tapping Screws Two expandable wall anchors and two No. 8 pan-head, self-tapping screws are included with each WRS-TTx Series Transmitter for surface mounting the unit as follows: 1. Remove the transmitter from its mounting base (as illustrated in Figure 2). 2. Select two mounting hole locations across from one another on the mounting base. Mark these two mounting hole locations on the wall surface using the mounting base as a template. Note: Before marking the two mounting hole locations, be sure that the rectangular holes with the little notches are towards the top. With the notched rectangular holes at the top, the transmitter is oriented properly once it is secured to the mounting base. 3. Drill a 5/32 in. (4 mm) hole at each of the marked locations. 4. Install an expandable wall anchor into each of the drilled holes. 5. Secure the mounting base to the surface using the two No. 8 pan-head, self-tapping screws provided. IMPORTANT: Do not overtighten the mounting screws. Overtightening the mounting screws may damage the mounting base and the mounting surface. 6. View the Property Code and Transmitter ID DIP switch arrays on the back of the transmitter. For a One-to-One application, set the Property Code DIP switch array to all “Zeros.” Set the address portion of the Transmitter ID DIP switch array to match the corresponding TE-78XX receiver DIP switch array. For a Many-to-One application, set the Property Code DIP switch array (1 to 31) and the address portion of the Transmitter ID DIP switch array (1 to 511) to desired addresses for the designated locations. (A “zero” setting is not allowed.) These addresses will be downloaded via the NAE to a WRS-RTN and be linked with specific Controllers. See the Setup and Adjustments section for more details. 7. Install the batteries into the battery compartment located on the back of the transmitter, and set the power DIP switch (top DIP switch on the Transmitter ID DIP switch array) to the ON position. 8. Place the bottom edge of the transmitter against the bottom lip of the mounting base and rotate the transmitter up onto the mounting base (as illustrated in Figure 3). Tamper-ProofTransmitter CoverHolding Screw Note: This diagram needs to be replaced with appropriate 80 X120 cover and base diagram Figure 3: Securing the Transmitter to the Mounting Base 9. Tighten the tamper-proof transmitter cover holding screw using a 1/16 in. (2 mm) Allen-head adjustment tool (T-4000-119; ordered separately) to secure the transmitter to the mounting base. Note: Once installed, the transmitter and mounting base assembly cannot be removed from the mounting surface without first loosening the tamper-proof transmitter cover holding screw and then depressing the tab at the top through the slot using a small coin or a screwdriver. (as illustrated in Figure 2). Surface Mounting the Transmitter Using Three Strips of Double-Sided Adhesive Foam Tape Each WRS-TTx Series Transmitter includes three 1/16 in. (2 mm) thick, 3/4 x 1 in. (19 x 25 mm) strips of double-sided adhesive foam tape for mounting locations where building retention and its historical preservation are important, or in buildings featuring marble, granite, glass, mirrored, wood veneer, or other decorative surfaces. To surface mount the transmitter using the three strips of foam tape, proceed as follows: 1. Remove the transmitter from its mounting base (as illustrated in Figure 2). 2. Clean the mounting surface to ensure that the foam tape holds the mounting base securely to the surface. Note: The application temperature must be at least 50°F (10°C). 3. Peel and stick one side of the foam tape strips to the smooth surface of the mounting base, arranged as illustrated in Figure 4.

(as illustrated in Figure 2). Setup and Adjustments For setup and commissioning details, refer to the WRS-TTx Technical Bulletin (LIT-??????????) Repairs and Replacement If the WRS-TTx Series RF Wireless Temperature and Set Point Transmitter, or the TE-7720 or TE-7730 Series RF Receiver, or the WRS-RTN Series RF Receiver fails to operate within its specifications, unit replacement is required. For a replacement transmitter or receiver, contact the nearest Johnson Controls representative. Table 2 includes the only replacement parts available for the WRS Series RF Wireless Room Temperature Sensing System. Do not attempt any repairs on the temperature sensing system other than those related to the replacement parts included in Table 2. Note: The printed circuit board used with the WRS Series RF Wireless Room Temperature Sensing System is retained with a tamper-resistant mechanism. Removing the printed circuit board from the plastic housing voids the product warranty. Replacing the Transmitter Battery The life of the 1.5-volt AA Alkaline batteries included with each WRS-TTx Series Transmitter is typically five or more years. The transmitter communicates diagnostic data, including battery condition, approximately every 60 seconds to the receiver, where it is converted into the appropriate units and electrical format to warn supervisory equipment (via the Johnson Controls digital controller) when the batteries needs to be replaced. For the WRS-RTN Series Receiver, a low battery signal is sent to the NAE via the Ethernet trunk, and this signal is not cleared until the transmitter battery is replaced. For the TE-7820 Series Receiver, a low battery signal is sent to the digital controller via the zone bus link, and this signal is not cleared until the transmitter battery is replaced. For the TE-7830 Series Receiver, the low battery relay binary output is turned off for 1 minute every 48 hours and then back on again. This function is intended to retrigger a system alarm that may have been acknowledged without taking appropriate action to replace the transmitter battery. See Figure 2 to remove the transmitter from its mounting base and access the battery for replacement. Replacement batteries must be purchased locally; suitable models include any good quality Alkaline (1.5V) or Lithium (1.6V) AA cells. Do not use Carbon/Zinc batteries as these will give a poor life and could give erratic operation.
