1 Introduction
This user manual describes the functions and features
of the Combio-868 LI system. Combio-868 LI enables
appropriate illuminants to switched and dimmed. Appro-
priate illuminants are as follows:
• standard light bulbs
• high-voltage halogen light bulbs
• low-voltage light bulbs with electronic transformer
• LED light bulbs with a suitable electronic dimmer
(ECG, electronic control gear)
An elero handheld/wall-mounted transmitter (at least 1)
is also required. The Combio-868 LI can be controlled
by several transmitters.
Follow the instructions in these manuals to ensure
proper and safe use.

5.5 Commissioning
The elero handheld/wall-mounted transmitter has to be
programmed to the Combio-868 LI radio receiver.
The functions of the Combio-868 LI are controlled using
the buttons [OPEN ▲], [STOP ■], [DOWN/CLOSE ▼],
programming button [P] and the slider of the handheld/
wall-mounted transmitter.
The + sign in the text indicates pressing the buttons
simultaneously.

5.7 Asynchronous programming mode
(standard)
Asynchronous programming mode is the standard pro-
gramming mode. In asynchronous programming mode,
the switch-on duration of the ON times vary in case of
several receivers. After a few ON/OFF cycles, the illu-
minants of the receivers will no longer light up synchro-
nously. This will enable the hits for a certain receiver to
be set better.
Asynchronous programming mode is suitable for
• programming the fi rst transmitter
• programming an additional transmitter
• programming individual receivers in case of several
receivers ready for programming (e.g. several
receivers using one fuse).
Asynchronous programming mode (standard)
Operating procedure Result
1 Activate asynchronous
programming standby:
Switch the mains voltage
off and on again or press
the buttons [OPEN ▲] +
[DOWN/CLOSE ▼] + [P]
simultaneously and hold
them down for 3 seconds
on a transmitter that has
already been programmed.
The receiver changes to
asynchronous program-
ming standby for 5 minu-
tes. Ready to receive the
programming button [P].

Ⓒ elero GmbH EN | 13
Asynchronous programming mode (standard)
2 Start programming mode:
Press the [P] programming
button for approx. 1 second.
Combio-868 LI changes
to asynchronous program-
ming mode and the light
source begins to change
intensity (between 100%
and 30%) periodically.
3Set fi rst hit:
Immediately after the light
source lights up, push
the [OPEN ▲] button or
[DOWN/CLOSE ▼].
• If luminous intensity is
high (100%) press the
[OPEN ▲] button.
• If luminous intensity is
low (30%) press the
[DOWN/CLOSE ▼]
button.
Hit successful:
The light source goes out
briefl y.
Hit failed:
The light source does not
go out. → repeat action
"Set fi rst hit"!
4 Set second hit:
Prerequisite:
First hit has been set.
Immediately after the light
source with the opposin-
gintensity lights up, push
the [OPEN ▲] button or
[DOWN/CLOSE ▼].
• If luminous intensity is
high (100%) press the
[OPEN ▲] button.
• If luminous intensity is
low (30%) press the
[DOWN/CLOSE ▼]
button.
Hit successful:
The light source goes out
permanently and indica-
tes that the programming
procedure is over.
Hit failed:
The light source does not
go out. → repeat action in
"Set second hit"!

• Programming can only ever be performed in one
selected channel.
• When programming is complete or after 5 minutes has
passed, the receiver will revert to normal operation.
• Programming mode can be stopped by pressing the
[STOP ■] button for at least 6 seconds.
• Up to 16 transmitters can be programmed.
• Several receivers can be programmed to one channel.
• If more than 10 receivers at once are in programming
mode, the transmitter changes to group program-
ming mode. Once programming is complete, group
programming mode has to be terminated manually in
the transmitter by pressing the [STOP ■] button for at
least 6 seconds.
5.8 Synchronous programming mode
Synchronous programming mode is a special program-
ming mode. In synchronous programming mode, the
switch-on duration of the ON times will be constant with
several receivers. Even after a few ON/OFF cycles, the
illuminants of the receivers will light up synchronously.
As a result, the hits for all participating receivers can be
set simultaneously.
Synchronous programming mode is suitable for
• programming an additional transmitter
• programming several receivers simultaneously to one
transmitter or one channel.

6.1 Adapting an illuminant
The factory setting of the Combio-868 LI allows a power
setting between 10% and 100%. The power cannot be
set below 10%. Some illuminants require more than
10% of the power at the lowest operating limit. This
could lead to the illuminant not lighting up yet a low level
of current fl owing regardless. In such cases the absolute
lower dimming limit should be adapted to the illuminant.
When adapting an illuminant, the absolute lower
dimming limit can be set or this can be reset to the
factory setting (10%).
In addition the Combio-868 LI can also be confi gured as
a light switch.

Requirement for adapting an illuminant
Operating procedure Result
Activate adaptation
of illuminant:
Switch the mains voltage off
and on again or press the
buttons [STOP ■] + [OPEN ▲]
+ [P] and hold them down for
6 seconds on a transmitter that
has already been programmed.
Combio-868 LI changes to
illuminant adaptation mode
for 5 minutes. Within this
time, settings can be made
for the absolute lower
dimming limit.
Setting the absolute lower dimming limit
Operating procedure Result
1 Set lowest user-defi ned
brightness value:
Using the [OPEN ▲] +
[DOWN/CLOSE ▼] buttons,
set the desired brightness
value and then briefl y press
the [DOWN/CLOSE ▼]
buttons + [STOP ■] button.
The set brightness value
is saved as the lowest
user-defi ned brightness
value.
2 Set absolute lower
dimming limit:
Press the buttons [OPEN ▲]
+ [DOWN/CLOSE ▼] briefl y.
The illuminant goes out.
The lowest user-defi ned
brightness value is set
as the absolute lower
dimming limit.

Confi guring the Combio-868 LI as a light switch
Operating procedure Result
Press the buttons
[OPEN ▲] + [DOWN/
CLOSE ▼] for 3 seconds.
The illuminant lights up. The
absolute lower dimming limit
is set to 100%. Combio-868 LI
now functions as a light switch.
Dimming will no longer work.
Restoring the absolute lower dimming limit
Operating procedure Result
Press the buttons
[OPEN ▲] + [DOWN/
CLOSE ▼] for 6 seconds.
The illuminant goes out. The
absolute lower dimming limit
of 10% is restored.
6.2 Deleting the programmed handheld/
wall-mounted transmitter
Deleting a transmitter does not eff ect the brightness
values set. Deleting a transmitter will cause the factory
setting to be restored.
Deleting the handheld/wall-mounted transmitter
Operating procedure Result
Press the [STOP ■] + [P]
buttons for at least
6 seconds until the
status LED lights up red.
On the transmitter:
The selected channels are
deleted entirely.
On the receiver:
