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 uorescent
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).

Installation
The FD3 U2E dimmer has a neutral line connection, so the lower load limit is 0VA. However, the dimmer must be operated
without a neutral connection with (HV) incandescent lamp loads over 100W to avoid EMC problems. In this case the neutral
terminal is jumpered to the load output. This has no effect on operation.
Optional; for improved heat dissipation with heavy loads
Standard connection Connection without neutral line
For dimmable LED, CFL and LV halogen lamps (with electronic or wound
transformers) up to the maximum rated load, and for HV halogen and incan-
descent lamps up to 100W

2. Setting the minimum brightness
= Phasenanschnittsteuerung
= Phasenabschnittsteuerung
The minimum brightness should be set depending on the lamp so that the on state of the lamp can still be recognised at
minimum brightness.
Set the “Dimmart” control to a dimming mode suitable for the lamp (see table)
Switch on the dimmer and dim down as far as possible. Then set the minimum bright-
ness to the desired level with the “Min.Hell.” control.
1. Setting the dimming mode
All suitable dimmable lamps can usually be operated in dimming mode 3 (Automatic).
Exceptions:
- Dimming mode 5 must be selected for lamps with wound transformers in a circuit with an automatic demand switch (use
with wireless operation is not practical).
- Dimming mode 2 (or if appropriate mode 4) must be selected for CFLs (compact uorescent lamps) which require an igniti
on and warm-up time.
CFL mode (dimming modes 2 and 4)
Most CFLs need full mains voltage for ignition. For this reason, this mode provides an ignition phase at half brightness before
adjusting to the last (saved) brightness level. A warm-up phase with elevated minimum brightness is also provided because
most CFLs have signicantly reduced minimum dimming capability (without going out) when cold. The minimum brightness
is gradually reduced to the normal value during the warm-up phase. The warm-up time depends on the off time, so the full
warm-up time (max. 1 minute) is only used when the lamp has been off for an extended time. If a CFL is switched off at very
low brightness and then switched on again when cold, the previous minimum brightness will be attained only after the warm-
up phase.
Automatic detection of wound transformers (dimming mode 3)
Wound transformers must be dimmed with forward phase control because reverse phase control generates inductive reverse
voltages that can destroy the dimmer if it does not detect them and switch off on time.
In this dimming mode the dimmer automatically changes to forward phase control after being switched on as soon as overvol-
tages (not yet dangerous) are detected. This setting is retained until loss of mains voltage. This dimming mode is not suitable
for use with automatic demand switches because the mains voltage is always disconnected after the lights are switched off.

mum brightness
„Sanft-EA“ (=soft on/off)
Soft switch-on and switch-off if activated (prolongs lamp life)
„Schlummer“ (=slumber)

4. Conguring wireless transmitters
The FD3 U2E is congured with the default settings when it is delivered. The following settings are pre-dened in this congu-
ration:
Input 1 Function: Toggling and dimming
Button 1 of a wireless transmitter with default settings Function: Toggling and dimming
5. Default settings
The FD3 U2E has a wired control input (terminal 1) and a “wireless input”.
In its default conguration, the FD3 U2E already responds to button 1 / channel 1 from transmitters that are also congured
with their default settings (address: DIP switches 1-8 in position “-”, level “A”, channel 1). The dimmer can already be switched
on/off (short push) or up/down dimmed (long push) using button 1 on the transmitter. Similarly, a wired button on terminal 1
may also be used for switching and dimming (as described above).
You can nd an overview of the default settings in Section 5.
Conguration process:
1) Press the Prog button briey → LED lights up
2) Press the desired button on the wireless transmitter → LED goes out
Restore default settings:
Press and hold the Prog button for 10s until the LED ashes 5 times.
The LED briey ashes red each time the operating mode changes.

Ambient conditions and troubleshooting
The LED is lit red in the on state (going out briey during the on/off ramp, going out
every 1s during Slumber mode, and going out every 2s during the CFL warm-up
phase). If a valid radio signal is received, it is (in addition) lit green. When input 1
receives a signal, the LED ickers green.
If a fault occurs, it displays a fault code.
The efciency of wound transformers and electronic loads (LEDs, CFLs and
electronic transformers) must be taken into account. The (primary) VA value is the
critical parameter for the dimmer. Electronic loads must be approved by the manu-
facturer for dimming with forward or reverse phase control dimmers.
The dimmer heats up during operation, depending on the connected load. The
connected load must be reduced if this heat cannot be dissipated adequately. Do
not mount dimmers close to heat sources.

General information:
Lamps approved for the same dimming mode can usually be used together. Incandescent lamps may always be operated in parallel. How-
ever, functional impairments occur fairly often when electronic loads from different manufacturers are operated in parallel, due to mutual
interference of manufacturer-specic ballasts and/or electronic transformers. Wound transformers may not be combined with electronic
loads. The dimmer is designed to work with as many different types of lamps as possible. However, it is not possible to guarantee trouble-
free operation of every dimmable lamp with the dimmer, since this can be affected by the design or construction of the lamp ballast or
transformer. Flickering or erratic dimming in the low brightness range with LED lamps and CFLs is usually due to the lamp being designed for
higher minimum input power. We recommend raising the minimum brightness setting in such cases. Ripple control signals from electricity
plants can lead to perceptible ickering of the lighting. The magnitude of this effect varies from one region to the next.
