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 designed 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.
