The ezDALI Group Controller (DLC) is a compo-
nent in an ezDALI system. It is the source of all
commands to the ballasts. In addition, it provides a
simple tool for creating ballast groups (a set of bal-
lasts that act in unison, also referred to as a zone),
and manual dimming of each group to create a pre-
ferred scene or preset. Automatic shut-off, in
compliance with energy codes, is achieved by con-
necting an occupancy sensor via the ezDALI Power
Supply.
Button Options
The ezDALI Group Controller is available in 2- or 4-
group models, both of which fit within a standard
single-gang wallbox. With the 2-group model, users
can create two different lighting groups, while the 4-
group model enables control of up to four groups.
Both the 2- and 4-group controllers allow the occu-
pant to create a preferred lighting level. Using the
Master button provides OFF/Restore capability.
Applications
The ezDALI Group Controller is ideal for use in
private offices, open offices and hallways. In each of
these applications, ezDALI allows the lighting to be
tuned to the needs of the occupant while also provid-
ing enhanced energy savings. Since it requires no
special tools or commissioning software, it can be
easily installed by an electrical contractor in any
building.
Operation
The ezDALI Group Controller operates with an
ezDALI Power Supply and one or more DALI bal-
lasts. Once each ballast has been assigned to a
group button on the ezDALI wallbox controller, a
user can raise or lower group light levels by press-
ing and holding the group button. This allows the
occupant to set each group to a preferred lighting
level. The Master button will toggle between the last
setting and off for normal daily operation.

Release. LEDs will
sequence while ballasts
are addressing.
Step 2. Create Groups
Press Select button. First ballast will turn on at
maximum level and all others will turn off. Press
