Installation Guide
Description
The Crestron
®
junction box-mounted zone controllers deliver intelligent lighting control
with essential features for energy efficiency. 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 Z
ū
m daylight sensors, occupancy sensors, vacancy sensors, keypads, and
dimmers (all sold separately) over the Z
ū
m mesh network, providing intelligent lighting
control based on the amount of natural light and the presence of people in a space. The
Z
ū
m J-Box Zone Controllers offer a powerful lighting control solution for every space
within the Z
ū
m network.
A basic single-room Z
ū
m system consists of Z
ū
m mesh devices, i.e., dimmers, switches,
keypads, and sensors. The Z
ū
m 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 Z
ū
m app on a smartphone or tablet.
