b) Installation
When installing the device please make absolutely sure that you carry out the
steps in the following order.
1. The ‘FS20 S4UB’ flush-mounted battery transmitter is normally installed in a deep
installation box. Before installing the device, you can mount an installation button, which
you can then use to operate the ‘FS20 S4UB’.
When choosing an installation location, make sure that there are no voltage-
carrying conductors in the immediate vicinity of the transmitter as these may
restrict the transmission range.
No sharp edges, sharp points or similar should be located at the installation
location. These could damage the insulating film and cause short circuits,
which could then destroy the flush-mounted battery transmitter.
Also make sure that you do not place the transmitter in a metal casing that is
closed on all sides (no radio signals possible).
If voltage-carrying conductors are laid in the designated installation box (or a socket or a
switch needs to be removed, in the case of multiple covers, for instance), then you should
take the following necessary measures:
First, switch off the respective electrical circuit by turning and removing
the relevant fuse or switching off the circuit breaker.
Make sure that nobody accidentally switches on the electrical circuit (safety
warning on the in-house distributor, mechanical block, etc.).
Then use a suitable measuring device to check whether the affected electric
circuit is fully voltage-free.
Only then should you continue (by removing the socket/switch covers, for
example).
2. Wire the flush-mounted battery transmitter with the external buttons as shown in figure 1
in section 5. a). Make sure that all the connections are securely fixed to the terminals of the
buttons.
All the unused wire ends of the ‘FS20 S4UB’ must be insulated using the
supplied covers and should not be connected anywhere else. Never shorten
the cables. If you require longer cables, use suitable terminal strips/junction
box terminals.

10
3. Insert the flush-mounted battery transmitter into the installation box.
Ensure that you leave enough space between any voltage-carrying cables/
terminal strips/junction box terminals and the ‘FS20 S4UB’ or that the cables/
terminal strips/junction box terminals are laid correctly. The insulation of older
power cords, in particular, is often damaged.
Not only do you risk destroying the ‘FS20 S4UB’, there is also the danger of
explosion or fire!
Insert or install the flush-mounted battery transmitter so that the integrated
buttons are not inadvertently pressed, when presetting an installation button,
for example, or laying cables.
Otherwise, switching operations could be accidentally triggered and the
battery life may also be reduced.
4. Install the desired number of control buttons in the installation box or boxes.
You can install as many buttons as you choose (you may only wish to install one button,
for example). If fewer than four buttons are installed, programming can only be carried out
via the buttons (‘TA1’, ‘TA2’, ‘TA3’ and ‘TA4’), which are integrated into the device.
Caution!
If the ‘FS20 S4UB’ is installed in a flush-mounted socket that also contains
voltage-carrying cables/terminal strips/junction box terminals, then certain
precautions need to be taken when operating the buttons.
Ensure that all voltage-carrying parts in the terminal box or distributor are laid
so that they cannot be contacted when the buttons on the ‘FS20 S4UB’ are
pressed.
Only press the buttons: Do not reach into the terminal box! When in doubt, use
an insulated VDE-approved screwdriver to press the buttons.
Otherwise there is the possibility of a life-threatening electric shock!
If you are operating the flush-mounted battery transmitter ‘FS20 S4UB’ as a 2-channel
transmitter, then the button combinations ‘TA1’/’TA2’ and ‘TA3’/’TA4’ each jointly belong
to a function unit. Bear this in mind when installing/setting up the connected buttons.

6. The FS20 address system
To enable several FS20 components (including the ‘FS20 S4UB’ flush-mounted battery
transmitter) to be operated in the same area, extensive coding is used to protect the radio
transmission.
The code consists of a ‘house code’ and an ‘address’. The house code serves to differentiate
between multiple FS20 systems operating simultaneously. This means that your neighbour
can use the same wireless control system and the two systems will not interfere with each other
(provided that the house code has been programmed differently).
The house code consists of 8 base-four digits (1, 2, 3, 4) meaning that in total 48(= 65536)
different house codes are possible. This makes it extremely unlikely that your neighbour will
use the same house code (assuming that you do not use ‘simple’ house codes).
The second part of the code is the so-called ‘address’. Every address is a four-digit number
made up of the following 16 numbers: 11, 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34, 41, 42, 43,
44
Example: Address 11 22
This means that there are a total of 256 different addresses (16x16 = 256). The addresses are
divided into four address types (available number is in brackets):
• Single addresses (225)
• Function group addresses (15)
• Local master addresses (15)
• Global master address (1)
Each address consists of two parts. Part 1 is the ‘address group’, part 2 is the ‘subaddress’.
Example: Address 11 22 = address group ‘11’, subaddress ‘22’
The number ‘44’ has a special meaning. Please see the table on the next page.

12
Address group Subaddress
Single address 44 44
Function group address 44 44
Local master address 44 44
Global master address 44 44
44 = This value must be set to ‘44’.
44 = This value must not be set to ‘44’.
Possible values are:
11, 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34, 41, 42, 43
Every receiver can be assigned one address from each of the four address types (single
address, function group address, local master address, global master address).
This means that each receiver can respond to up to four different addresses, but only ever to
one address per address type.
If you need a receiver to respond to more than one transmitter, you can program
the transmitters to the same address or, if different transmitter address types
have been set, you can program the receiver consecutively to these different
addresses.
The individual address types have the following function:
• Single addresses
Each receiver should be set to a single address so that it can be controlled separately.
• Function group addresses
Several receivers are defined as a functional unit by being assigned to a function group
address. If, for example, all the lamps in a house are assigned to a function group, then all
the lamps in the entire house can be switched on or off by pressing one button.
• Local master addresses
Several receivers are spatially defined as one unit and controlled via the local master
address. If, for example, all the receivers in a room are each allocated to a local master
address, then all you need to do is press one button when leaving the room to switch off
all the consumer loads in the room.

13
• Global master address
Several receivers are assigned to the global master address and are jointly controlled via
this address. All the consumer loads can easily be switched off simply by pressing one
single button when leaving a house, for example.

Figure 2: Example of an address assignment

14
A different address group has been assigned to each room:
• Room A: 11
• Room B: 12
An awning is also allocated to room B.
• Room C: 13
• Room D: 14
When you require a large, extended system, it is advisable to select addresses systematically
so that you have an overview of the addresses that have already been assigned and so that
you can jointly control the programmed receivers simply and logically in groups.
If you plan to use a number of different FS20 components, draw a diagram of
the rooms and make a note of the location of the devices to be controlled and
their addresses in the diagram.
In the example, each room has been assigned its own address group (room A: 11, room B: 12,
room C: 13, room D: 14). The awning is also allocated to room Bwith address group 12.
15 address groups are possible:
11, 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34, 41, 42, 43
This value must not be set to ‘44’.
In order to be able to separately control each receiver, you need to program each one to a
single address. In addition to the address group that is already selected (room A: 11, room B:
12, room C: 13, room D: 14), a subaddress is also needed.
The following 15 subaddresses are possible for each address group:
11, 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34, 41, 42, 43
This value must not be set to ‘44’.
In the example the awning is programmed to the single address 1211, which is comprised of
the address group 12 and the subaddress 11.
All the receivers in room A have also been programmed to a local master address (1144 in the
example).
For the local master address 44 must always be used as the subaddress. The
address group can be set to 11, 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34, 41,
42, or 43.
Example: 1144, address group 11, subaddress 44
All the lamps in the house can be controlled via the global master address 4444.

15
The awning was deliberately not programmed to this address and can therefore only be
addressed via its single address (1211). It must be operated separately in this example.
The ceiling lamps in all the rooms are also combined in a function group (4411 in the example,
address group 44, subaddress 11) and can therefore be jointly controlled.
For a function group 44 must always be used as the address group. The
subaddress can be set to 11, 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34, 41, 42,
or 43.
Example: 4411, address group 44, subaddress 11

7. Operation
Please note:
In the delivery state the components of the FS20 wireless control system (a
wireless switch socket, for example) do not respond to remote control com-
mands from the flush-mounted battery transmitter. They must first be ad-
dressed according to the instructions provided in the respective device’s user
manual.
Only afterwards can the functions be controlled.
a) Basic functions
Buttons are pressed briefly (to switch) or for longer than 0.4 seconds (to dim), as required.
In the delivery state each of the four buttons is allocated to a different channel; the ‘FS20
S4UB’ is factory set to ‘4-channel operation’.
• Switching
Pressing a button briefly (for fewer than 0.4 seconds) sends a ‘TOGGLE’ command
(changing between two switch states).
• Dimming
If a button is pressed for longer than 0.4 seconds, the corresponding dim command (‘DIM-
UP & DIM-DOWN’) is sent until the button is released.
When the ‘DIM-UP & DIM-DOWN’ command is issued, a lamp is dimmed up to the
maximum and then dimmed down to the minimum, etc.
The ‘dim direction’ is always the opposite direction to the command that was previously
sent. If, for example, the last command caused a lamp to dim up, then pressing the button
again would result in the lamp dimming down.
Now you can program and operate the basic functions of the FS20 components.
If you require an extended system with several components or you wish to use
the additional functions, please also read the following sections.

17
b) Using several transmitters
In the delivery state each transmitter in the FS20 wireless control system has its own, randomly
set house code.
If you want to jointly control one or several receivers via different transmitters,
you first need to coordinate the transmitters’ house codes. The same house
code must be set for each transmitter.
Make sure you coordinate or set this shared house code for all the
transmitters before programming the receivers for the first time, as the
associated house code is also sent to the receiver during this procedure.
The transmitters’ channels are already set to the same addresses and only need to be changed
if required, for example, if you are using an extensive FS20 wireless control system with
numerous receivers/transmitters.
Please also see the example in section 6.
c) Timer function in 4-channel operation
Buttons ‘TA1’/‘TA2’ or ‘TA3’/‘TA4’ constitute a button combination for
programming a receiver’s timer function.
Proceed as follows to program the device:
• Press and hold down the button that is assigned to the receiver.
• Press the other button of the button combination for one to five seconds (1s to 5s) and then
release it.
• Only afterwards should you release the button that you pressed first.
These steps apply to starting as well as to stopping the timer programming.
For information on how to program the timer, see the instructions in the receiver’s user manual.

18
d) 2-channel operation
The ‘FS20 S4UB’ flush-mounted battery transmitter can be operated as a 2-channel transmit-
ter as well as 4-channel transmitter (factory default setting).
In the case of 2-channel operation a button combination is assigned to each channel.
Channel 1:Buttons ‘TA1’ and ‘TA2’:
Channel 2:Buttons ‘TA3’ and ‘TA4’:
The button assignment for the four buttons is as follows:
Button ‘TA1’ or ‘TA3’: Function ‘OFF’ or ‘dim down’
Button ‘TA2’ or ‘TA4’: Function ‘ON’ or ‘dim up’
e) Switching between 2-channel and 4-channel operation
• Switching to 4-channel operation (four individual switching channels)
Press buttons ‘TA2’ and ‘TA3’ simultaneously for at least 5 seconds.
• Switching to 2-channel operation (two switching channels with two buttons each)
Press buttons ‘TA1’ and ‘TA4’ simultaneously for at least 5 seconds.
Please note:
Different operating and programming instructions apply when a double number
of channels has been set!
f) Timer function in 2-channel operation
In order to program a receiver’s timer function, proceed as follows:
•Simultaneously press the button combination that is assigned to the receiver for one to
five seconds (1 sec to 5 sec).
This command is used to start as well as to stop the programming of the timer.
For information on how to program the timer, see the instructions in the receiver’s user manual.

8. Integrating the ‘FS20 S4UB’ into the address
system, programming
A house code, an address group and a subaddress are used for coding the flush-mounted
battery transmitter ‘FS20 S4UB’ and its switching channels. You can also use special address
group assignments to program the wireless transmitter as a local or global master.
The 4 buttons ‘TA1’, ‘TA2’, ‘TA3’ and ‘TA4’ are used for entering the eight-digit
house code, the two-digit address groups and the two-digit subaddresses, see
figure 1.
This addressing makes 225 single addresses, 15 function groups, 15 local master addresses
and 1 global master address available for use by the ‘FS20 S4UB’ within each house code.
a) Setting the house code
Once the operating voltage has been switched on, the ‘FS20 S4UB’ flush-mounted battery
transmitter selects a random house code. As the transmitter is supplied with a preinstalled
lithium battery, its random house code is also preset at the factory.
If required, this house code can be changed as follows:
• Keep the ‘TA1’ and ‘TA3’ buttons on the flush-mounted battery transmitter pressed for 5
seconds.
• Now use the ‘TA1’, ‘TA2’ , ‘TA3’ and ‘TA4’ buttons to enter your system’s eight-digit house
code. This must be identical for all the remote control transmitters in the FS20 wireless
control system (as a precaution, make a note of this code and keep it safe).
Example: 23141342 1 = Button ‘TA1’, 2 = Button ‘TA2’,
3 = Button ‘TA3’, 4 = Button ‘TA4’,
• The programming mode ends automatically once you have entered the eighth digit.

20
b) Setting the addresses
A channel’s address is comprised of a 2-digit address group and a 2-digit subaddress (for
example, 1131, address group 11, subaddress 31).
The address group ‘11’ is factory set for all channels.
If several transmitters are to be operated at the same time and control different receivers, then
different addresses need to be set on the transmitters.
1. Programming a single address in 4-channel operation
For programming purposes buttons ‘TA1’/’TA2’ and ‘TA3’/’TA4’ constitute a
button combination.
To change the single address (address group/subaddress) for a single button, proceed as
follows:
• Press and hold the button to be programmed.
• Then press the other button of the button combination and keep both buttons pressed
simultaneously for a minimum of five seconds.
• Then release both buttons.
• Use the ‘TA1’, ‘TA2’ , ‘TA3’ and ‘TA4’ buttons to enter a two-digit address group and a two-
digit subaddress.
Example: 1431 (address group 14, subaddress 31)
• The programming mode ends automatically once you have entered the fourth digit.
The following address combinations are preassigned to the buttons:
Buttons 1 2 3 4
Address 11 11 11 12 11 13 11 14
Please note:
The address group 44 and the subaddress 44 both have a particular meaning.
See section 6.
