WT-ROUTER Router Installation Instructions

3

To determine if routers are required in a mesh network 
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.

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.

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 operate 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.

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.
