ZUMMESH-JBOX
Zūm™ J-Box Load Controller
Installation Guide
Description
The Crestron® junction box-mounted zone controllers deliver intelligent lighting control
with essential features for energy efciency. Available for 20 A switching, 5 A or 16 A
0-10 V dimming, and 20 A plug load control, each ZUMMESH-JBOX model wirelessly
connects to Zūm daylight sensors, occupancy sensors, vacancy sensors, keypads, and
dimmers (all sold separately) over the Zūm mesh network, providing intelligent lighting
control based on the amount of natural light and the presence of people in a space. The
Zūm J-Box Zone Controllers offer a powerful lighting control solution for every space
within the Zūm network.
A basic single-room Zūm system consists of Zūm mesh devices, i.e., dimmers, switches,
keypads, and sensors. The Zūm mesh devices in the room communicate directly with
each other without the need for a centralized gateway or processor.
To monitor or control the room from a centralized Crestron control system, use the
ZUMMESH-NETBRIDGE.
NOTE: The ZUMMESH-NETBRIDGE requires a J-box device to provide power.
For quick network setup, use the Zūm app on a smartphone or tablet.

Preliminary
Basic Room Setup
A basic single-room Zūm system consists of Zūm mesh devices, i.e., dimmers, switches,
keypads, and sensors. The Zūm mesh devices in the room communicate directly with
each other without the need for a centralized gateway or processor.
To set up a new single-room Zūm system, do the following:
Step 1a: Create a new single-room Zūm system.
Step 2: Add Zūm mesh devices to the room.
Step 3: Finish creating the single-room Zūm system.
To modify an existing Zūm system, do the following:
Step 1b: Place the system in Joining mode.
Step 2: Add Zūm mesh devices to the room.
Step 3: Finish creating the single-room Zūm system.
Step 1a – Creating a Single-Room Zūm System
To create a new single-room Zūm system, rst form a new room.
NOTE: This can be performed on only one device in the room.
NOTE: The device that is used to create the room is automatically added to the room.
The device does not need to be added to the room.
NOTE: A room can be created only from an ac-powered device.
Start a New Single-Room System with a Keypad, Dimmer, or Switch
Press the bottom button 5 times, and then press and hold the bottom button for
2 seconds. If the device is not factory fresh, hold the button for 10 seconds. Release the
button when the LED lights. The LED illuminates for 3 seconds and then slowly ashes to
indicate that the room is in Joining mode and that other devices can join the room.
Step 1b – Expanding an Existing Single-Room Zūm System
To allow other devices to join the room, place the single-room Zūm system into Joining
mode. Joining mode can be enabled from any ac-powered device or battery keypad that
is already part of the room.
Expand a Single-Room Zūm System Using a Keypad
To enter Joining mode, press and hold both the top and bottom buttons for 5 seconds,
wait for the LED to light, and then tap the top button once, and then the bottom button
once.

Pressing any button on a device that is part of the network takes the system out of
joining mode. Joining mode ends automatically after 4 minutes.

Factory Reset
Perform a factory reset when the device is removed from the network or to remove the
conguration settings. The device must also be factory reset if the device is being moved
to a different system.
NOTE: New-in-box devices do not need to be factory reset before joining a system.
To factory reset the device, press and hold the TEST and SETUP button for 10 seconds.
Release the button when the LED lights. The LEDs and output will turn on.

Install Network Bridge
The Zūm Network Bridge enables Zūm device setup from a mobile app and integrates a
stand-alone Zūm lighting control system with the Zūm hub (not supplied) for a centrally
managed, enterprise-wide lighting control system. The network bridge can be installed to
any J-box device.
1. Using a at-head screwdriver, remove the cover on the J-box device.
2. Ensure that the connector on the network bridge is aligned with the expansion port
on the J-box, and then insert the network bridge into the J-box device. The
network bridge snaps into place.

Step 2 - Adding Zūm Mesh Devices to the Room
Adding Zūm mesh devices to a room is quick and easy. Add devices to the room when
the room is in Joining mode. Joining mode is automatically enabled after a single-room
Zūm system is started (see Step 1a). Joining mode can also be enabled manually (see
Step 1b).
The LEDs on all ac-powered devices in the system blink when the system is in Joining

mode.
NOTE: A Zūm mesh device can belong to only one room.
NOTE: The Zūm mesh device used to create the room is already part of the network. It
does not need to be added to the network.
To add a J-box dimmer or switch to the room, press the SETUP button 3 times, and then
press and hold the SETUP button for 2 seconds. If the device is not factory fresh, hold
the button for 10 seconds. Release the button when the LED lights. The LED blinks
slowly to indicate that it is part of the room and that the room is still in Joining Mode.

TEST
If necessary, the network bridge can be easily removed. To remove the network bridge,
do the following:
1. Between the J-box and the J-box device, press the side of the network bridge with
your thumb away from the J-box.
2. While pressing on the side of the network bridge, slightly lift the network bridge up
and out of the J-box device. The network bridge should easily remove from the
J-box device.
