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 Zūm daylight sensors, occupancy sensors, vacancy sensors, keypads, and
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

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.
