General information

The FD3 U2E wireless universal pushbutton dimmer can dim
a wide variety of lamps (LED, CFL, incandescent, LV halogen
with electronic or wound transformer, HV halogen).
Along with automatic detection of wound transformers
("Auto" dimming mode), the dimming mode can be set
manually to forward or reverse phase control if necessary
(especially for lamps with electronic ballasts or electronic
transformers). A special CFL dimming mode additionally pro-
vides an ignition and warm-up delay for compact fluorescent
lamps ("energy-saving lamps")
The compact dimensions of the FD3 U2E allow it be installed
in electrical boxes behind a button switch from any desired
product line, making it equally suitable for new installations
as well as for maintenance-free replacement of existing or
defective rotary or button dimmers.

Operation

A short button press toggles the lamp; a long press increa-
ses or reduces the brightness.

Functions

"Slumber" function (e.g. as an aid to help children fall
asleep)
When this function is activated by dimming the lamp, the
light level is dimmed down very slowly, with a duration that
depends on the brightness at the start of dimming (duration
from maximum brightness: 60 min.).
"Discreet dim in" function
In response to a long button press when the lamp is off, the
dimmer switches on and dims up from the minimum bright-
ness.
„Sync" function
If several dimmers are controlled by a single button, they
may become unsynchronised because the button command
(toggle) is not unambiguous.
Synchronisation is achieved by holding the button pressed
long enough (approximately 10 s) for all dimmers to dim
down to minimum brightness and then stop at maximum
brightness (maximum level).
