1. General safety instructions
The use of defective equipment can lead
to personal injur y and damage to property.
Never use defective or damaged equipment.
Please contact our Customer Service department in this event .
2. Correct usage
Correct usage
Only use the DuoFern wall controller 3216 02 21 / 3216 02 11
for the remote control of:
◆ Shutters / Blinds
◆ Electrical consumers (for instance lighting)
Operating conditions
◆ Only use the DuoFern wall controller in dry rooms.
◆ The installation and operation of the DuoFern radio sys-
tem and its components (e. g. DuoFern tubular motor
actuator) is only permitted for systems and devices
where a malfunc tion in the transmitter or receiver
would not cause a danger to personnel or property or
where this risk is already covered by other safety equipment.
3. Incorrect use
Never use the DuoFern radio system and its components for
the remote control of appliances and systems with increased
safety-relevant requirements or where there is an accident
risk. This would require additional safety equipment. Observe the respective statutory regulations for the installation
of such systems.
IMPORTANT
Do not install the DuoFern wall controller outside.

4.1 Functional description
Use the DuoFern wall controller to manually operate diverse
DuoFern actuators remotely. To do so, connect the DuoFern
wall controller to the required DuoFern network.
Use the two rocker switches to send manual control commands to the connected DuoFern actuators.
A bi-coloured indicator light shows whether the DuoFern
actuators connected to the wall controller have received and
conrmed the control commands. The indicator light is concealed behind the two rocker switches.

4.2. Two operating modes
1. Tubular motor mode
The following control commands are sent in Tubular
motor mode: UP/STOP/DOWN
NOTE
Every DuoFern actuator reacts to these commands. Please additionally read the operating instructions for the DuoFern actuator.
2. Lighting/Devices mode
The following control commands are sent per rocker
switch: ON/OFF
NOTE
◆ The DuoFern actuator is in Tubular motor mode when
it leaves the factory.
◆ The individual channels of an actuator can be distributed
to the two rocker switches in Lighting/Devices mode.
◆ Only the DuoFern actuators that suppor t On/O switch-
ing commands react to the Light/Devices mode (e. g.
the DuoFern universal actuator or the DuoFern socket
actuator.)

5. Installation procedure
1. Perform all of the setting s req uired with the
keypad.
2. Select a suitable installation site.
The installation site should preferably be at and free
of dust.
3. Pull one of th e two protec tive films from the

6. Dismantling
1. Dismantle the wall controller in reverse order.
7. Login of DuoFern end devices
You must assign the wall controller to every required
DuoFern actuator so that the DuoFern wall controller can
control a DuoFern actuator.
You can login a maximum of 32 DuoFern actuators at the
wall controller, for instance RolloTron Standard or Comfort
DuoFern; D uoFern actuators (Tubular motor actuator or
universal actuator) etc.
1. Switch the DuoFern actuator to Login
mode (please refer to the correspon ding operating instructions).
2. Switch the wall controller to Login mode.
- To do so, press keys 1 and 2 simultaneously and
hold down for approx. 5 seconds.
3.a The wall controller is in Tubular motor mode
(factory setting)
No further conguration is needed - all of the channels
of an actuator are operated at the same time.
3.b The wall controller is in Lighting/Devices mode.
Every channel of the actuator must be assigned to a
rocker switch. The indicator light will continue to show
orange until all of the channels of an actuator are assigned.
Proceed as follows:
- Key 1 to operate the channel with the left
rocker switch.
- Key 2 to operate the channel with the right
rocker switch.
- Press key 3 or 4 in order not to operate the channel.
NOTE
Refer to the table in chapter 4.3. for the changeover
between Tubular motor mode and Lighting/Devices
mode.
3.c Pay attention to the indicator light:
Green: Login was successful.
Red: Login failed.
4. Login the next DuoFern actuator.

motors or switches the function of switching actuators.
NOTE
◆ The direction of rotation/reversal of function is only
available if precisely one actuator is logged in on the
key. With multichannel actuators, all of the channels
logged in on the key are switched over.
◆ Not every actuator supports this functions, so
please read in the relevant operating instructions for the actuator whether this function is
available.
