About the Crestron ZUMMESH-JBOX-16A-LV
The controller is rated 16A at 100-277VAC, 50/60 Hz, and dims 0-10V LED drivers or 4-wire fluorescent ballasts through a 0-10VDC output rated at 60 mA maximum. It also switches the load, with a red 14 AWG switched load lead alongside the black line and white neutral leads, plus 18 AWG purple and grey leads for 0-10V positive and negative. Idle power consumption is 1 W.
Zūm Mesh 2-way RF at 2.4 GHz (IEEE 802.15.4) links it to other Zūm devices up to 50 ft (15 m) away, subject to site conditions. Keypads and occupancy, vacancy and daylight sensors pair with it, a SETUP button handles room setup and factory reset, and a TEST button toggles the load and cycles the dimming level. An expansion port accepts a ZUMMESH-NETBRIDGE for Zūm Net (sold separately) or a ZUMMESH-CCO.
It mounts to the side of a 4 in. square junction box through a 1/2 in. conduit knockout, projects 93 mm from the box and meets the requirements of UL 2043. The unit measures 83 x 106 x 34 mm and operates from 0° to 40°C. The ZUMMESH-JBOX series also includes a 5A dimmer, a 20A switch and a 20A plug load controller, so match the full part number when replacing one.

Questions about the Crestron ZUMMESH-JBOX-16A-LV
What is the Crestron ZUMMESH-JBOX-16A-LV?
It is a Zūm wireless J-Box load controller with a 0-10V dimmer, rated 16A at 100-277V. It mounts to a 4 in. square junction box, dims 0-10V LED drivers or 4-wire fluorescent ballasts, and pairs with Zūm keypads and sensors over Zūm Mesh as part of a Zūm commercial room lighting system.
How does the ZUMMESH-JBOX-16A-LV differ from the ZUMLINK-JBOX-16A-LV?
Both are 16A, 100-277V J-Box controllers with 0-10V dimming. The ZUMMESH-JBOX-16A-LV communicates wirelessly over Zūm Mesh and has an expansion port for a Zūm Network Bridge or Contact Closure Output. The ZUMLINK-JBOX-16A-LV is the wired version, connecting to Zūm Link keypads and sensors through RJ-45 ports.
What can connect to the expansion port?
The expansion port accepts a ZUMMESH-NETBRIDGE, sold separately, which provides Zūm Net wireless communications, or a ZUMMESH-CCO, which adds a low-voltage contact closure output for HVAC integration. Zūm Net has a range of 50 ft (15 m) to a Zūm Net wireless gateway or the nearest Zūm Net mesh device.
What connections does the ZUMMESH-JBOX-16A-LV have?
It uses 14 AWG Class 1 flying leads: black for line, white for neutral and red for the switched load. The 0-10V dimming output is on 18 AWG purple (positive) and grey (negative) leads, rated 0-10VDC at 60 mA maximum. A SETUP button handles room setup and factory reset, and a TEST button toggles the load.
How is it mounted?
It mounts to the side of a 4 in. square junction box through a 1/2 in. conduit knockout and projects 93 mm (3.66 in) from the box. It meets the requirements of UL 2043, measures 83 mm high, 106 mm wide and 34 mm deep, and operates from 0° to 40°C.
How much is the Crestron ZUMMESH-JBOX-16A-LV?
Crestron asks its dealers to give the price of the ZUMMESH-JBOX-16A-LV directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the ZUMMESH-JBOX-16A-LV?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the ZUMMESH-JBOX-16A-LV on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the ZUMMESH-JBOX-16A-LV come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the ZUMMESH-JBOX-16A-LV develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the ZUMMESH-JBOX-16A-LV in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the ZUMMESH-JBOX-16A-LV without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
