2 Safety
The Unio-868 is not intended to be used by people (in-
cluding children) with limited physical, sensory, or mental
aptitude, or lack of experience and/or knowledge, unless
they are supervised by a person responsible for their safety
or have received instruction from this person as to how the
Unio-868 is used.
• Never allow children to use electrical devices unless
they are supervised.
2.1 General safety instructions
The Operating Instructions contain all safety instructions
which must be observed in order to prevent dangers inher-
ent to handling the Unio-868 in connection with the compo-
nents to be switched. A safe use of the Unio-868 can only
be ensured when all given safety instructions are observed.
The Unio-868 is maintenance-free.
• Do not open the Unio-868; it does not contain any parts
that need to be serviced by you.
• Only operate the Unio-868 in dry inner rooms and avoid
inuence of moisture, dust and direct sunlight. Avoid any
wetness or high humidity, extreme cold or heat, dust or
ammable gases, steams or solvents, strong vibrations
and strong magnetic elds at the site of use or during
transport.
• Never use the Unio-868 when it has been taken from a
cold to a warm room. The resulting condensation may
destroy the Unio-868. First let the product reach room
temperature without switching it on.
• Do not touch the Unio-868 and the mains plug of the de-
vice that you want to plug in to the Unio-868 with moist
or wet hands!
• Only load the Unio-868 to the indicated power limit.
Overload may cause destruction, re or electrical ac-
cident.
• Before each use, check the Unio-868 for damage. If you
nd any damage, the Unio-868 must not be connected
to the mains voltage. There is a danger to life!
• Before cleaning, disconnect the Unio-868 from the mains
socket and any connected device from the Unio-868.
• Clean the Unio-868 with a dry and lint-free cloth, which
may be moistened slightly in case of severe contamina-
tion, and only after disconnection from the mains outlet.
Do not use any solvent-containing cleaning agents for
cleaning. The plastic housing and labels may be at-
tacked.
2.2 Requirements for the personnel

3 Product description
3.1 General information
The Unio-868 is an easy to handle radio switching outlet
with many usage options that permits the comfortable wire-
less switching of electric mains-powered devices across
large distances. The Unio-868 has (bidirectional) routing
functions.
The Unio-868 is connected between the outlet of the electri-
cal household installation and the electrical consumer to
be controlled. Only such devices must be used that have a
mains plug and mains voltage range that ts the specica-
tions of the Unio-868. The connected consumer must not
exceed the maximum switching output of the Unio-868 (see
nameplate).
The environment for intended application of the Unio-868 is
the residential and business area, as well as small industry.
The Unio-868 must not be used to control devices where
malfunction may cause a danger to persons, animals or
property.
Interferences from other radio and telecommunication
systems that work on the same frequency band cannot be
fully excluded.
Radio operation is only permitted with released transmitters.
3.2 Scope of supply
The purchased product includes the following:
• Unio-868
• Operating instructions
3.3 Accessories
• elero radio transmitters
• elero radio sensors
3.4 Bidirectional radio system
The term bidirectional radio system means the transmission
of radio signals to radio receivers and the response option
for the radio receivers to the transmitter. The radio signal
can be sent directly to the target receiver. If this is not pos-
sible, the radio signal will be routed via other bidirectional
participants until it reaches the target receiver. The target
receiver carries out the command and sends a conrmation
back to the transmitter. The prerequisite for a bidirectional
radio system is hence the radio transmitting capability as
well as the radio reception capability of all participating
components.
3.5 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
transmitter. It is also not possible to transmit radio signals
from radio receiver to radio receiver.
3.6 Prerequisites for operation
• 230-volt socket outlet
• (one or more) elero radio transmitter
3.7 Preparations for operation
WARNING!
Danger of injury due to electric current.
Protect yourself from electrical shock. Use the corre-
sponding care when handling electrical current.
Plug the Unio-868 into a mains socket and connect a con-
sumer, e.g. a lamp, to the outlet of the Unio-868.

ing the operating button (switching condition switches from
ON to OFF or from OFF to ON).
3.8.3 Operation by hand-held transmitter
STOP button (■) OFF (xed)
UP button (▲) ON or OFF,
depending on teaching direction
DOWN button (▼) OFF or ON,

3.8.4 Operation by automatic devices
(clocks and/or sensors)
• Up to 16 transmitters (sensors, hand-held / wall transmit-
ters) can be taught in to the Unio-868. Permitted radio
sensors are: Lumo, Lumero, Sensero and Aero. The
Sensero and Aero only evaluate the light telegrams.
• The last command received is executed.
• An automatic switching function that is overwritten by
the hand-held / wall transmitter is executed according to
the SmartStart/semi-automatic rules. SmartStart/semi-
automatic causes condition changes of the Unio-868 to
be performed only when the condition of the transmitting
sensors has changed rst.
• If the automatic function is switched o󰀨, the Unio-868
will only react to the operation button and the hand-held
transmitters anymore. The Unio-868 will then not react to
sensor and timer commands, except for prioritised alarm
and clock commands.
• The Unio-868 controls the twilight function of the trig-
gered sensors. When using the twilight function of the
Lumo, a manual switching command or a clock switching
command is to be used to revoke the twilight switching
condition.

14 | EN Ⓒelero GmbH Ⓒelero GmbH EN | 15
• Double commands (double UP or double DOWN) are
treated like "single" running commands (UP or DOWN).
This means that the Unio-868 is generally not suitable
for ventilation and interim position running strategies.
Switching times never limit themselves independently.
Automatic STOP commands are ignored.
• Switching from manual mode to automatic mode resets
all sensor functions.
• Central channel switching commands are ignored.
3.9 Teaching in (programming)
The purpose of teaching in is programming one or several
transmitters for the Unio-868.
By teaching in the rst transmitter, the radio operating mode
of the Unio-868 is specied for the elero ProLine mode or
elero ProLine 2 mode - according to the transmitter to be
taught in.
• Mixed operation of ProLine 1 transmitters and
ProLine 2 transmitters is not possible.
Connect the Unio-868 to a mains outlet.
The Unio-868 is in teaching mode for 5 minutes.
Teaching mode is signalled by one ash of the LED:
When the Unio-868 receives the radio signal from a
pushed programming button P (or teaching button P)
during these 5 minutes, the Unio-868 is put in learning
mode for 2 minutes.
Learning mode is signalled by the ashing LED.
• Fast ashing (approx. 10 Hz) = ON
• Slow ashing (approx. 2 Hz) = OFF
In learning mode, the Unio-868 switches its switching condi-
tion (OFF / ON) every 3 seconds. Between the switching
conditions, there is a break of one second each. The learn-
ing sequence is started with the switching condition ON.
3.9.1 Teaching in hand-held/wall transmitters, clock
transmitters
When teaching in hand-held/wall transmitters and trans-
mitters with clock function, the switching condition (ON or
OFF) may be taught in in any assignment to the UP/DOWN
running commands of the sensors.
Teaching in switching condition ON:
Push the button UP or DOWN once while the light is
ashing quickly to set a hit.
Teaching in switching condition OFF:
Push the button DOWN or UP once while the light is
ashing slowly to set a hit.
Teaching is completed.
If several transmitters from the group of the hand-held/
wall transmitters and from the ground of clock transmitters
are taught in to the Unio-868, the last transmitter taught in
determines the assignment of all transmitters to this group.
• Important:
The Unio-868 does not react to manual central channel
commands.
3.9.2 Teaching of sensors (sensor transmitters)
When teaching in sensors (sensor transmitters), the switch-
ing condition (ON or OFF) may be taught in in any assign-
ment to the UP or DOWN buttons of the Unio-868.
Teaching in switching condition ON:
Push the button UP or DOWN once while the light is
ashing quickly to set a hit.
Teaching in switching condition OFF:
Push the button DOWN or UP once while the light is
ashing slowly to set a hit.
Teaching is completed.

16 | EN Ⓒelero GmbH Ⓒelero GmbH EN | 17
If several sensors have been taught in to the Unio-868, the
last sensor taught will determine the assignment of all sen-
sors from the sensor transmitter group.
• Important:
Wind sensors have a higher priority than light sensors
where assignment of the switching conditions is con-
cerned.
