WIRING Attach the wires from the device terminals to the appropriate receiver terminals. CAUTION Improper Electrical Contact Hazard. Screw type terminal blocks are designed to accept no more than one 16 AWG (1.31 sq. mm) conductor. Connect multiple wires that are 16-18 AWG
(1.31-0.82 sq. mm) with a wire nut. Include a pigtail with this wire group and attach the pigtail to the individual terminal block. Wire the terminal block as follows:
2. 1. For single wires, strip 3/16 in. (5 mm); for multiple wires going into one terminal, strip 1/2 in. (13 mm) insulation from the conductor. If two or more wires (18 to 22 AWG only) are being inserted into one terminal, twist the wires together before inserting. NOTE: When two or more wires are being inserted into one terminal, be sure to twist them together. Deviation from this rule can result in improper electrical contact. See Fig. 4. Insert the wire in the required terminal location and tighten the screw to complete the termination. 4. Review and verify the terminal connection wiring and DIP switch settings. 1/2

TESTING FOR SIGNAL STRENGTH When the receiver is powered and batteries are placed in the wall module, communication will begin automatically within 2 seconds. The receiver RF signal light will flash every 30 seconds to confirm each transmission. You can force immediate communication by pressing the signal strength button on the side of the wall module with a 1-1.6 mm diameter probe with flat or rounded face (a common paperclip will do) (see Fig. 9). This may be required to initiate communication when replacing a wall module. The signal strength LED next to the signal strength button will light up on the side to show the relative signal strength. The signal strength LED will initially light amber when the signal strength button is pressed to verify that you are pressing the signal strength button. When you release the signal strength button, the light will behave as shown in Table 1. 5 62-029107 TR21-WS, TR23-WS, TR21-WK, TR23-WK, WRECVR 70 0 6 8 0 TEMPERATURE DIAL, FAHRENHEIT DIAL SHOWN LED BYPASS

LED Signal Strength Remains Green for 5 seconds Strong Remains Amber for 5 seconds Weaker (still acceptable) Amber blinks for 5 seconds No signal If no signal is received, test the wall module in a different location until a suitable signal strength is received by the receiver. Pressing the signal strength button on the wall module will cause a five-second flash on the RF signal LED on the receiver, and pressing the override button will cause a single flash on the receiver. If communication is lost between the wall module and receiver, the receiver will try three times to reestablish communication. After 3 tries (90 seconds), the receiver will go into a sleep mode, and will retry to communicate every 10 minutes. Output from the receiver will be an open circuit for temperature and setpoint output (simulating cut wires on a wired sensor). Communication will re-establish automatically once signal is within range. BINDING THE WALL MODULE AND RECEIVER TO EACH OTHER The TR21-WK and TR23-WK wireless kits include a wall module and receiver that have already been bound in the factory to automatically communicate with each other. They can be identified as matching by the identical bind numbers printed on the labels. The S2 and S3 DIP switches on the receiver (used to bind the two devices) and the 12 DIP switches on the wall module will all be in the OFF position. As soon as power is applied to the receiver and the batteries are installed in the wall module, the two devices start to talk to each other. If the two devices dont communicate immediately, 62-029107 6 remove and re-install one battery, leaving it out for 10 seconds OR you can initiate communication by pressing the signal strength button on the sensor (using paperclip). Each wireless kit has a unique binding, so even though multiple wireless kits have S2 and S3 switches all in the OFF position, each device will only communicate to the device to which it was paired and shipped as a kit. There may be times when you want to bind a receiver to a wall module using the DIP switches. This is done simply by matching any S2/S3 DIP switch settings on the receiver with the DIP switch settings on the wall module. Wall modules in close proximity must have different DIP switch settings
(except when modules are using the all-OFF default binding). DIP switches S2/S3 are provided for two reasons:
If the wall module needs to be replaced, a TR21-WS or TR23-WS wall module can be purchased. To bind any wall module and receiver, simply set the DIP switches S2/S3 on both the receiver and the wall module to any matching DIP configuration. To prepare for this ahead of time, the receiver and wall module in the WK kit can be set with a matching dip switch configuration when mounted. The tear off tab on the receiver allows the installer to write down the on/off DIP configuration. Then the new wall modules DIP switches can be set by matching the old wall modules DIP switches, without having to set or check the DIP switches on the receiver. If wall modules and receivers get mixed up in the field
(even though they are marked with matching numbers from the factory), DIP switches can be used to bind any wall module to any receiver simply by matching the S2/S3 DIP switches. If setting DIP switches, be sure that each wireless sensor/receiver pair in a given building has a unique DIP switch setting to prevent cross-talk. Fig. 8 shows matching DIP switch settings binding the wall module and receiver. Controller Matching The TR21 and TR23 wireless wall modules can be used with many different controllers. The S1 switch on the receiver can be set for a number of different controller requirements. See Table 2 for DIP switch settings, and see Table 3 for a description of the controller. Table 2.

Common Temperature (Override button temporarily shorts the temperature output) Setpoint Low Battery Signal When there are approximately 2 months of battery life remaining, the LED on the front of the wall module (next to the Override button) will flash red every 15 seconds. In addition, the LOW BAT digital output from the receiver will close. This LOW BAT output signal can be sent to an unused DI on the controller to let the user know that there is a low battery condition. Replace the batteries whenever the LOW BAT contact closes, or flashing red light is seen next to the Override LED on the face of the wall module. Normal operation will automatically resume. NOTE:
If the batteries go dead, the LOW BAT digital output
(open/close) signal will open again. The LOW BAT digital output will close only when batteries are run-
ning low, not when they are completely dead, or are not installed. This ensures that a lack of signal is not confused with dead or missing batteries. Whenever there is no signal, or batteries have gone completely dead, the receiver LOWBAT output will send an open circuit reading to the controller for temperature (and set point, if applicable). Override Button To save battery life, the override button LED will only light when the button is pressed. It will not remain lit, as on standard wired TR23 and TR24 models. Override will still be activated when the button is pressed. If using with the XL10, pressing and briefly holding the override button will cause it to behave like other standard wired TR23s. The LED will remain lit for 9 seconds max. to confirm it has been pressed from 1-4 seconds. REPLACING A WALL MODULE When replacing a wall module, set the DIP switches the same as the wall module being replaced. If the previous wall module DIP switches are all set to OFF, it will be necessary to reset the S2 and S3 receiver dip switches to any configuration not being used by other receivers in the area, and then set the wall module DIP switches to the same setting. At least one of the 12 DIP switches must be set to the ON (up) position. General Rules for Installing Wireless Wall Modules Communication between the wall module and receiver can be influenced by a number of factors. Type and thickness of building materials and the way in which they are oriented in relation to the wall module and receiver will affect communication. Do not place either the wall module or receiver inside metal cabinets or enclosures.Try to orient the wall module and receiver so that if they are separated by a wall(s), the direction of signal travel is as perpendicular to the wall(s) as possible. This reduces the effective wall thickness. When mounting the receiver on a metal duct, stronger communication is possible if the wall module is on the same side of the duct so the signal doesnt need to travel through the metal duct. Reduce as much as possible the amount of metal (ducts, file cabinets, etc.) between the sensor and the wall module. Standard drywall (gypsum board) does not greatly affect signal strength. For the most robust wireless link, install the wall module in locations with the strong signal (Green light as described in Table 1). 7 62-029107 TR21-WS, TR23-WS, TR21-WK, TR23-WK, WRECVR LONWORKS is a registered trademark of Echelon Corporation.
