Introduction
The ST2134 Blind Control Module SC 4-fold is a special control for blinds with SC 3-wire connection
(e.g. SL MB blinds). Due to the fully digital and bidirectional communication between ST2134 and the
blind motor control unit (inside the blind/motor controller) the ST2134 realize precise position control
and feedback and therefore allows perfect sun tracking and integration into building management
systems.
Due to the standard network interface (Ethernet LAN with RJ-45 socket) the necessary network
infrastructure is built up with most common and efficient Ethernet network technology or can even be
integrated in existing network infrastructure.
Without any analog timing or manual operations, the blinds can easily be controlled to any target
position (height and angle). Smart homes and smart buildings can integrate blinds controlled by
ST2134 perfectly with visual user interface and scenes.
IMPORTANT NOTICE
Some functions in this manual depend on special blind types and maybe not available for any blind
type and must be confirmed from control and blind manufacturer and need in any case detailed
knowledge of the entire blind system. Please contact control, blind and glass supplier for details.

Quick Start
Focus of ST2134 and ScreenTronic® app is easy and intuitive configuration and operation of smart
blind control for everybody without special technical knowledge.
Only two touch operations on the ST2134 and one touch operation in the ScreenTronic® app (or
operation of local switch connected to ST2134) are necessary to make full configuration of one blind:
Preparation
1) Download ScreenTronic® app from Apple App Store, start application and confirm standard
configuration.
In development:
A small project is automatically created (if there is not already an old project in the app) and
first blind control is added to first zone and the corresponding graphical blind control is shown.
2) Connect the blinds and power supply to ST2134 and integrate the ST2134 in same network
(Wi-Fi) of the iOS device (iPod touch, iPhone or iPad) and power the ST2134.
Note: The network must provide a DHCP server.
Warning: Take installation instructions in consideration!
The connected blinds are automatically initialized (Init): checked, addressed and blind
configuration read (e.g. blind type (venetian, roller, …), tilt only, tilt time, …) and the channel
behavior of ST2134 matched to the connected blind.
Note: this may take up to one minute (until green LED “Init” switches off).
Configuration
(Assignment of a blind to a control group or a local control switch)
3) Press Blind select button of ST2134 -> Blind 1 is selected
(cyan LED indicates selected blind / another touch selects next blind)

4) Press Group add/set button
(cyan flashing LED indicates activation of group learning mode for the selected blind)
5) Operate the graphical blind control in ScreenTronic® app or operate a local control switch
connected to ST2134 to link the blind to the control group or the local control switch
(confirmation tone indicates successful adding of the control group or switch to the blind)
6) Configuration for first blind is ready and you can control the blind with the ScreenTronic® app
or the local control switch already.
For adding another blind to the same control group repeat step 3) – 5) with next blind.
For a new control group in the ScreenTronic® app select menu / edit (pen symbol) / + in the app and
repeat step 3) – 5) for desired blind.

Operation
With the ST2134 an easy and powerful operating concept on the surface of each ST2134 is
introduced. All necessary configurations can be performed with few touch operations direct on the
device.
User Interface
The user interface consists of:
 5 x RGB LED
 3 x RG LED
 6 x Touch button
 Acoustic touch and status confirmation (PIEZO)
After powering the ST2134 the connected blinds are initialized. During this sequence (up to one
minute) the Init LED is green and Power LED shows cyan for blind initialization (Init) operation.
In normal operation the Power LED is green.

Direct Blind Operation
After installation of ST2134 and connection of blinds it is very helpfull to be able to test the blind
function direct on the user interface of the ST2134.
To operate a blind for test purpose:
1) Select blind (1, 2, 3, 4 or ALL) with Blind select button
(cyan LED indicates selected blind / another touch selects next blind)
2) Press Arrow Up or Down button for blind operation of the selected blind
short touch (<0,6s): Move blind fully up / down
long touch (>0,6s): Tilting of blind (as long as pressed) / stop

13
Initialization (Init)
The initialization (Init) of all connected blinds is performed always after power on of the ST2134
device. The sequence can be additional started at any time as follows.
To start the Init sequence manually:
1) Press Blind select and Switch select button exactly at same time for min. 1s
(green Init LED (between the 2 buttons) indicates the processing of the Init sequence)
Make sure to press the 2 buttons exactly at same time to avoid starting the separate functions of the 2
individual buttons.
During initialization (Init) the ST2134 is addressing the blinds with address 1 to 4 corresponding to the
output channel number, is reading the blind parameter for correct control setting (e.g. blind type, tilt
time, …) and is activating the setting of the parameter 3-Wire-Only in the blind configuration.
New connected blinds
After connecting a new blind (e.g. changing a blind/channel or using the ST2134 with new blinds) an
initialization (Init) must be performed - otherwise the new connected blinds won’t work.

ST2134 Operation and Installation Manual
14
Diagnostic
The initialization (Init) function is as well very helpful for diagnostic of the correct blind wiring. If during
Initialization (Init) the communication to a blind is not possible or faulty (e.g. no blind connected, wiring
problem, …) the corresponding Blind LED lights red after initialization (Init) procedure.
IMPORTANT
Take in consideration that the blinds once connected to ST2134 are not reacting on 2-pole controls
(e.g. ST2121 or mechanical switch of ST1811) any more until parameter 3-Wire-Only is changed back
to OFF value (with CTS for blinds software).

15
Referencing (Ref)
With the referencing the positions of the virtual end limits (top and bottom) are cleared and set to a
defined distance from the mechanical end stops of the blind. For this purpose, an automatic sequence
with movements to the end positions is performed with the blind.
To start referencing of end limits for a blind:
1) Select blind (1, 2, 3, 4 or ALL) with Blind select button
(cyan LED indicates selected blind / another touch selects next blind)
2) Press Group add/set and Group delete button exactly at same time for min. 1s
(green Ref LED (between the 2 buttons) confirms the starting of the Ref function)
Make sure to press the 2 buttons exactly at same time to avoid starting the separate functions of the 2
individual buttons.

ST2134 Operation and Installation Manual
16
Referencing
1) Blind moves up to virtual top end stop.
2) Blind goes on moving up to mechanical top end stop (slat package pressing).
3) Blind moves down to virtual bottom end stop.
4) Blind goes on moving down to mechanical bottom end stop.
5) Blind moves up to a position above the virtual bottom end stop (slats are tilting to inside).
6) Blind moves down to the virtual bottom end stop (slats are tilting to outside).
IMPORTANT
After starting referencing (Ref) function of a blind do not send any control (move or tilt) commands to
the blind until referencing of the blind is finished.
Due to the forces to the mechanical system and the cords, referencing should be performed only
whenever necessary and, in any case, not regularly.

Lock
With the Key Lock function it’s possible to block the user interface and avoid the ST2134 device from
involuntary operations.
To activate / deactivate the Lock:
1) Press Arrow up and Arrow down button exactly at same time for min. 1s
(green Lock LED (between the 2 buttons) confirms the active Lock function)
Make sure to press the 2 buttons exactly at same time to avoid starting the separate functions of the 2
individual buttons.
After power down and repowering of the ST2134 device the same Lock state as before is activated.

18
Control Groups
To each of the 4 blinds connected to a ST2134 it is possible to assign different control groups. In
general the logic of group assignment starts from blinds side view:
For each blind (=output channel of ST2134) it is necessary to assign all control groups (graphical
control in the ScreenTronic® app or local control switch) on which the blind should react.
A control group is defined by its control group ID. In the settings of each blind control in the
ScreenTronic® app the ID can be changed before using it. The local control switches of each ST2134
has a predefined and unique control group ID. See chapter Local Control Switches and Remote Input
for details.
Control Group add
To add a control group or local control switch to a blind:
1) Select blind (1, 2, 3, 4 or ALL) with Blind select button
(cyan LED indicates selected blind / another touch selects next blind)
2) Press Group add/set button
(cyan flashing LED indicates activation of group learning mode for the selected blind)

3) Operate blind control group in ScreenTronic® App or local control switch to add the control
group to the blind.
(long confirmation tone indicates successful adding of the control group to the blind)
(short confirmation tone indicates that the control group was already assigned to the blind)
