STR-4D
Roller blind controller
for 12/24 V DC
The STR-4D controller is designed to control roller blinds (
) or other objects (e.g. gates) that are driven with DC elec-
tric motor supplied by 12 V or 24 V with momentary switch (eg.
bell).
The controller can operate as a stand-alone device (for opening/
closing of a single roller blind), but it is also possible to combine
controllers into groups to control multiple roller blinds. Roller
blind motor starts after momentary passing of the "+" signal to
one of the control inputs. The motor activates for the user-pro-
grammed time that allows to fully lift or lower the roller blind.
Roller blind can be stopped on the user-selected level (incomple-
te opening or closing of the roller blind).

Do not dispose of this device in the trash along with other waste! According
to the Law on Waste, electro coming from households free of charge and
can give any amount to up to that end point of collec� on, as well as to sto-
re the occasion of the purchase of new equipment (in accordance with the
principle of old-for-new, regardless of brand). Electro thrown in the trash or
abandoned in nature, pose a threat to the environment and human health.

Controller control inputs are divided into two groups: local con-
trol and central control.

Depending on how you connect the controller, it can operate in
one or two local buttons mode.
One local button
Local control input  is connected permanently to the "+"
(plus) line. Local control input  is connected to a button that
alternately switches the roller blind to move up or down. Short
press (<0.5 s) switches on the blind for a programmed time.
Pressing the button when the roller blind is already in motion
causes the roller blind to stop. Long press (>0.5 s) switches on
the roller blind for as long as the button is pressed. Each time
you press the button the roller blind will move in the direction
opposite to the previous one.
Two local buttons
Each direction of movement has its own local button. Short press
(<0.5 s) switches on the roller blind to move in a given direction
for the programmed period of time. Pressing the button when
the roller blind is already in motion causes the roller blind to
stop.
Long press (>0.5 s) switches on the roller blind to move in a gi-
ven direction for as long as the button is pressed (this allows for
example to adjust the tilt of slats).
Control

- 3 -
Memory of direction applies both to local and central
control. For example, if the controller carries out a
 command, then the next press of a local
button will move the roller blind down.
Memory of direction is not retained after a power fa-
ilure.

The controller always works with two central control inputs.
Central control allows the roller blinds to move only in the de-
sired direction. Roller blind will stop only after a preset time or
by pressing any of the local control buttons.
If during the execution of one center control command another
one is issued with the instruction to move in the opposite direc-
tion, the roller blind will stop at first and after 1.5 s will then start
to move in the opposite direction. Time of roller blind activation
can be randomly delayed in the control center (up to 1 s) – to
minimize the current surge in the grid in case of simultaneous
activation of multiple controllers.

 button can also close and lock the roller
blind in the closed position. If the  button
is pressed and left in the  position, the controller will
close the roller blind and will not allow for its opening
until the  button is released (other inputs
will then be locked). This function allows you to lock the
roller blinds e.g. when the alarm is armed or when the
rainfall (if the additional STR-R rain sensor is used) or
too strong wind (if the additional STR-W wind sensor is
used) is detected.
When preparing the installation powered with 12/24 V
voltage, it is necessary to provide a power source with
sufficient current capacity to supply all receivers. Too
small power supply may lead to improper operation of
motors and roller shutter controllers. Additionally, vol-
tage drops on cables (mainly power cables) should be
taken into account and, if necessary, the diameter of the
cables should be increased to reduce the voltage drop.
1. Disconnect the power supply.
2.Mount the controller on the rail in the distribution box.
3.Connect the controller accordingly to the selected scheme of
operation.
4.Switch on the power supply.
5.Program the time of lifting/lowering the roller blind.
Assembly

- 5 -
Time of activation can be programmed upon the assumed time
of roller blind operation or by activating the roller blind for the
test run.
Scheduling for the specified time
1.Press and hold (for approx. 4 s) the  button until the
green U LED will begin to flash slowly. The controller is now
ready for programming.
2.Short press  button – the controller starts to measure out
the activation time, which is indicated by rapid flashing of U
LEDs.
3.After the time has been measured out, press the  button
again. The controller will save the elapsed time in non-volatile
memory and then exit the programming mode, which is indi-
cated by the constant U LED light.
Test run
1.Place the blind in the outmost top or bottom position.
2.Press and hold (for approx. 4s) the  button until the green
U LED will begin to flash slowly. The controller is now ready for
programming.
3.Short press the local control  or  button (in the oppo-
site direction to the current position of the roller blind). The
controller starts the motor and begins to measure out the
time.
4.After the time has been measured out, press any of the local
control buttons. The roller blind motor will stop and the con-
troller will save the elapsed time in "non-volatile" memory and
then exit the programming mode.

If during the first 30 seconds of the learning mode (slow
flashing of U LED) the time measuring will not start (the
 button is pressed or the roller blind is activated
from the local control input), the controller will exit the
learning mode.
The controller is designed to measure time span shorter
than 15 min. Attempting to set the controller for longer
span will result in exit from the learning mode.
The controller learning mode can be started only when
the roller blind motor is turned off.
Operation with factory settings (activation time set to 30
seconds) is indicated in standby mode by short (0.1 s)
blinking of U LED repeated every 4 s.
