2 Explanation of functions
2.1 Functions of the Lumo-868
• Sun function
When the value set at the sun threshold controller is
exceeded, the roller shutter moves until the Lumo-868 is
completely shaded and then moves back until the Lumo-
868 is exposed entirely again.

8 | EN Ⓒelero GmbH
• Twilight function:
The twilight function causes the roller shutter to move
down either at commencement of twilight or only at dark-
ness.
Interim steps can be set at the twilight threshold controller
and the function can be switched offentirely.
• Glass breakage function:
The glass breakage sensor, which can be deactivated,
recognises glass breakage on request at vibrations of
the Lumo-868 and will then move the roller shutter all the
way down.
2.2 Bidirectional radio system
A bidirectional radio system transmits radio signals to a
radio receiver and enables feedback from the radio receiver
to the radio transmitter. The radio signal can be sent directly
to the target receiver. If this is not possible, the radio sig-
nal will be routed via other bidirectional participants until it
reaches the target receiver. The target receiver executes
the command and then sends a confirmation back to the
radio transmitter - at programming and deletion processes.
The prerequisite for the bidirectional radio operation is a
radio-transmitter and a radio-receiver capacity for all prod-
ucts involved. The system thus only works unidirectionally.
2.3 Unidirectional radio system
A unidirectional radio system transmits radio signals to radio
receivers. However, unlike in a bidirectional radio system,
the radio receiver cannot send any message back to the
radio transmitter. It is also not possible to transmit radio
signals from one radio receiver to another radio receiver.

Ⓒelero GmbH EN | 9
2.4 Group control unit
A group is understood to mean the control of several radio
receivers at the same time. The selected group is controlled
by a travel command.
You can program any number of radio receivers in each
radio transmitter.
2.5 Commissioning
• The prerequisite for commissioning of the Lumo-868 is an
inserted functional battery (as in the delivery condition).
When the battery is discharged, replace it with a model of
the same type as described in chapter 2.11.
• Attaching to a suitable window position. For this, moisten
the location a little if required.
• Activate the Lumo-868 with any button; the status display
lights up.
Important:
Do not push the STOP-/P-button before the radio receiver
is ready for programming. In learning mode, the Lumo-868
chooses a radio system (uni- or bidirectional). When the ra-
dio receiver is not in learning mode, the Lumo-868 switches
to unidirectional mode.
To reach the starting condition again, push the 3 operat-
ing buttons UP, STOP-/Pand DOWN at the same time for
6 seconds until the status display lights up briefly.
2.5.1 Meanings of the status display
A radio signal is indicated by lighting up of the status dis-
play. The various colours of the status display mean:

Status indicator Meaning
Flashing
orange
Lumo-868 not programmed at any
radio receiver

mode
Operation of already programmed radio
receivers is not possible.
Orange Lumo-868 works bidirectionally:
Transmit signal is being sent
Green Lumo-868 works unidirectionally:
Transmit signal is being sent
The maximum sending range within a building is up to 10
metres. Reducing battery output reduces the transmission
output and thus the transmitter range.
If the performance of the battery drops, the status display
slowly loses its illuminative capacity.
If the status display no longer lights up when you press a
button, the battery must be replaced (cf. chapter 2.11).
2.5.2 Opening and closing the Lumo-868
• Turn housing lid (upper housing shell) approx. 2 mm
clockwise and lift it off.
• When closing the housing lid, observe the correct posi-
tion of the inner latching hooks and the intended cut-outs:
Put on the housing lid and turn it approx. 2 mm counter
clockwise.

Ⓒelero GmbH EN | 11
2.6 Programming Lumo-868
Requirements:
The radio receiver is installed.
• For bidirectional use, the device version of the installed
radio receiver is relevant:
elero Combio from version 75 onwards,
elero RevoLine from version 21 onwards or
elero radio receiver from manufacturing date May 2012.
Check whether the channel is deleted or in the correct
mode according to the status display.
Stand in front of the roller shutter to be programmed while
programming.
1. With electrical, previously installed drives, turn the safety
of the drive offand then on again after a few seconds.
The drive is now in programming mode for about 5 min-
utes.
2. Push the button STOP-/Pfor more than 2 seconds. The
status indicator is lit briefly. The roller shutter moves up
and down automatically briefly and continually for approx.
2 minutes to show that the drive is in programming mode.
3. To define the button assignment for moving the roller
shutter up and down, push the button UP of the Lumo-
868 right after an upwards movement starts (1 second).
The status indicator is lit briefly. The roller shutter stops
briefly and then moves up.
4. Push the button DOWN of the Lumo-868 at once after a
movement down starts. The status indicator is lit briefly.
The roller shutter will stop.
The Lumo-868 is now programmed.
Important:
Programming will have to be repeated if the roller shutter
does not stop.
When programming ist complete or after 5 minutes has
passed, the receiver will revert to normal operation.

12 | EN Ⓒelero GmbH
A bidirectional programming process in the Lumo-868 can
be cancelled by pressing the STOP button for 6 seconds.

The procedure for determination of the desired sun thresh-
old is done by setting, observing and, if required, correcting
a selected setting.
• If the brightness measured by the light sensor is exceed-
ed for more than 3 minutes in relation to the chosen sun
threshold, the roller shutter moves down.
• If the brightness measured by the light sensor is undercut
for more than 15 minutes in relations to the sun thresh-
old, the roller shutter moves up.
2.8.4 Setting twilight threshold
(encoding switch 2)
Important:

The procedure for determination of the desired twilight
threshold is done by setting, observing and, if required, cor-
recting a selected setting.
• If the brightness measured by the light sensor is under-
cut for more than 10 minutes in relations to the chosen
twilight threshold, the roller shutter moves down all the
way to the lower end position.
The roller shutter will not automatically move back to the top
end position - via the Lumo-868.
The roller shutter must be manually opened with the UP
button at the Lumo-868, a timer or another programmed
radio transmitter.
2.8.5 Encoding switch setting for regular operation

High Low

Ⓒelero GmbH EN | 19
In order to achieve a high sensitivity of the glass breakage
sensor, mount the Lumo-868 so that the script is horizontal
(in parallel with the window sill).
A low sensitivity can be reached by attaching it swapped by
180° (elero script upside-down).
When the glass breakage sensor is shaken (e.g. because
window pane breaks), the glass breakage sensor is acti-
vated and causes the roller shutter to move to the lower end
position.
In this case, all automatic switching commands of a radio
transmitter programmed for the roller shutter (hand-held
transmitter, wall-mounted transmitter or timer) are blocked.
Manual operation is possible at any time, however.
The block of the automatic running commands is revoked
by a manual running command at a radio transmitter pro-
grammed for the roller shutter.
2.8.7 No function (encoding switch 4)
Encoding switch 4 is without function, any position.
2.9 Deleting the programmed sensor
The communication of the Lumo-868 with a radio receiver
(e.g. drive) is permanently deleted.
• Push the buttons UP, DOWN; STOP and Pconcurrently
for at least 6 seconds
The status display flashes briefly.
The Lumo-868 is deleted from the radio receiver/s.
2.10 Replacing the battery
The Lumo-868 is supplied with power via a lithium button
cell of type CR-2032 with 3 V. When the battery is flat, the
Lumo-868 switches offautomatically. A weak battery is
indicated by a weaker status display.

20 | EN Ⓒelero GmbH
Important:
Replace battery only with batteries of the identical type.
1. Open the housing as described in chapter 2.5.2 and
loosen the lid.
2. Remove the battery.
3. Enter the new battery (of type CR2032) in the correct
orientation (observe polarity).
4. Close the housing.
