Refer to the QuickLIT website for the most up-to-date version of this document.
Application
The WT-ROUTER Router relays wireless transmissions from a Johnson Controls® WT-4000 Series Pneumatic-to-Direct Digital Control (DDC) Room Thermostat to other WT-ROUTER Routers or to a Johnson Controls WT-BAC-IP Gateway. Adding routers to a wireless mesh network enhances the robustness of the network by extending the wireless mesh communication range up to 750 ft (229 m). In addition, the routers provide multiple routes of communication with the gateway.
The WT-ROUTER Router installs in minutes with no need to run network cables. An STS LED indicator (Figure 1) allows for strategic positioning in areas with reliable network connectivity. The router is powered by a low-voltage 5 to 30 VDC power supply.
The WT-ROUTER Router is de signed for indoor, intra-building applications only. The router uses direct-sequence, spread-spectrum RF technology, and operates on the 2.4 GHz Industrial, Scientific, and Medical (ISM) band. The router also meets the IEEE 802.15.4 standard for low power, low duty cycle RF transmitting systems.
IMPORTANT: Use the WT-ROUTER Router only to provide an input to equipment under normal operating conditions. Where failure or malfunction of the router 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 router.

Mounting
The WT-ROUTER Router can be surface mounted using two field-furnished screws. Mount the unit to the surface at the two mounting hole location s on the device (Figure 1).
The router can also be secured to a bracket above a drop ceiling using field-furnished tie wraps.
Location Considerations
The WT-ROUTER Router must remain powered up at all times to operate properly. Choose an installation location where the power supply cannot be accidentally unplugged. An ideal location for the rout er is abov e a drop ceiling with a dedicated power source.

installation, check the network status of all the WT-4000 Series Room Thermostats in the network. If the signal strength indicator shows good network communication with the WT-BAC-IP Gateway, then no routers are required. If the signal strength indicator shows poor network communication with the gateway, then routers are required to extend the range of transmissions up to 750 ft (229 m). Try to position the router somewhere between the devices that are offline and the devices connected to the network.
Note: Avoid installing the router near equipment that may interfere with the 2.4 GHz RF signal, such as cordless telephones or Wi-Fi access points that operate on the 2.4 GHz ISM band.
2. Document the device ID and location of each router on the floor plan prior to installation. The device ID sticker is located on the back of the router.
Note: You may opera te the router while it is resting on a desktop or mounted to a wall. If the router is mounted to a wall, be sure to secure it in place using the appropriate fasteners (field furnished).
3. Plug the power adaptor (included with the router) into a 110/120 VAC outlet, then plug the power jack on the power supply cable into the power connector on the side of the router (Figure 1).
4. If the PWR LED indicator is not green, remove the connector panel access cover and slide the OFF/ON switch to the ON position (Figure 1).
5. Reinstall the connector panel access cover.
6. Confirm that the STS LED on the router (Figure 1) and the signal strength indicator on the WT-4000 Series Room Thermostat indicate good wireless communication between the devices.
In order for the devices to connect to the same mesh network, they all must have the same Group ID. The Group ID is set at the factory and cannot be changed in the field. Figure 2 illustrates the white sticker on the back of the router that shows the location of the Group ID.
Installing the WT-ROUTER Router
To install the WT-ROUTER Router:
1. Position the router in an indoor location with good wireless reception. Verify that the router is within 100 to 250 ft (30 to 76 m) of the other devices in the mesh network.
Repair Information
If the WT-ROUTER Router fails to operate within its specifications, replace the unit. For a replacement router, contact the nearest Johnson Controls representative.
