Johnson Controls WT-ROUTER Installation guide

Brand: Johnson Controls

Model: WT-ROUTER

Type: Installation guide

Johnson Controls WT-ROUTER allows you to extend the reach of your wireless network for your HVAC system with enhanced roaming capabilities. It uses a mesh network to create multiple routes of communication with the gateway, ensuring a reliable connection even in complex or large buildings. The router is easy to install and can be mounted on a wall or ceiling. It has multiple status indicators to help you troubleshoot any issues. The router is powered by a low-voltage 5 to 30 VDC power supply and meets industry standards for low power, low duty cycle RF transmitting systems.

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 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.

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.

Industry Canada Statement

The term IC before the certification/registration

number only signifies that the Industry Canada

technical specifications were met.

Le terme « IC » précédant le numéro d'accréditation/

inscription signifie simplement que le produit est

Status Indication LEDs

The WT-ROUTER communicates status using the

following LEDs:

• STS LED—Blinking indicates that the router is

connected to the wireless network with only one

active path. This LED remains on if two or more

wireless paths exist.

• ACT LED—On steady indicates that there is RF

traffic at the device.

• PWR LED—On steady indicates that power is

applied to the device.

Installation

Follow these guidelines when installing the

WT-ROUTER Router:

• Transport the router in the original container to

minimize vibration and shock damage.

• Verify that all the parts shipped with the router.

• Do not drop the router or subject it to physical

shock.

• Do not attempt to open the router housing or repair

the device; the router is not user serviceable.

Parts Included

• one WT-ROUTER Router

• one power adaptor

• one installation instructions sheet

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 locations 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 router is above a

drop ceiling with a dedicated power source.

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.
