Description
The Arexa window control system has been developed for the automatic control
of a window (or a group of windows) and for comfortable manual operation. The
control system offers a highest degree of flexibility for installation and setting
and may therefore be adjusted individually to different conditions. Please
anxiously use this instruction manual in order to adjust the automatic function to
your requirements.
Scope of supply
The Arexa window control system consists of weather station and operating
unit. Batteries for the operation of the operating unit are included in the scope of
delivery (2 pcs.).
Commissioning procedure
Installation, inspection, commissioning and troubleshooting
of the control system must only be arried out by a competent
electrician.
Proceed as follows when commissioning the Arexa control system:
1. Installation and connection (see chapter „Installation and commissioning")
2. Basic setting (see chapter „Basic settings“)
3. Setting of the automatic (see chapter „Setting of automatic")
Options for connection and control
A drive mechanism for windows may be connected to the Arexa control system.
If several windows shall be controlled together, the connection via a group
control relay is possible.
The following environmental parameters are measured and displayed:
•Outdoor and indoor temperature
•Lightness
•Wind speed
•Precipitation

4
Arexa may be deployed in the control system XS as control centre and as
transducer. In this case, the control is upgraded with motor control units and
operating units of system XS.
Overview of available automatic functions
•Open when a selectable indoor temperature is reached
•Close and keep closed below a selectable outdoor temperature (outdoor
temperature block)
•Open until a programmable position is reached
•Close when a selectable wind speed is reached (wind alarm, function may
be deactivated)
•Close in case of rain (rain alarm, function may be deactivated)
The window is closed in automatic mode as soon as the value of a set indoor
temperature falls below or in case of rain/wind alarm.
The wind and rain protection functions are also active in manual mode if they
have been set in automatic.

Display of lightness and wind speed
Press the key during temperature display once for a short moment, and
current lightness (in kilolux, kLux) and wind speed (in meters per second, m/sec)
are displayed. The values are updated every 4 seconds.
Note: During the first approx. 90 seconds after the return of voltage at the
weather station, the wind value is not displayed correctly (e.g. after a power fail
or in case of a first start). Therefore, manual operation is blocked in this period of
time in case of activated wind alarm.
If you press the key again for a short moment, you get back to the
temperature display (or to the central command display, see next chapter). After
approx. 60 seconds, the display switches automatically to the temperature
display.

Manual operation
Manual control as well as the presetting of the automatic functions and the basic
setting of the connected shading is accomplished with the keys of the operating
unit.
Up Stop Down
The connected window may be manually operated with the keys , and .
The arrow keys are provided with a time automatic. By short pressing (less than
1 second), the window may be exactly positioned. If the key is pressed more
than 1 second, the drive mechanism moves automatically to the final position. If
you press , the drive mechanism stops.
In case of rain or wind alarm, the manual operation is blocked.
Manual/automatic
Key switches between automatic mode (display ) and manual mode
(display ). After the manual operation with the keys , or , the control
system is in manual mode. The automatic functions then are deactivated, there
is no control in terms of temperature. With key , the control is reset to

You may leave the automatic settings at any time by pressing the key . The
accomplished changes of the values are not saved in this case.
If you do not press any key in the automatic settings for 5 minutes, the display
automatically changes to temperature display. Accomplished settings are not
saved either.
A. Indoor temperature for opening
In the automatic settings, you must indicate at first the lightness from which
shading shall start.
As soon as the value indicated here is exceeded, the automatic opens the
window (unless the blocking value for the outdoor temperature has fallen below,
see next parameter)
The presetting is 25°C.
Adjust the value with (higher) and (lower) or select (off) in order to
switch off the function. You reach the setting by pressing once more
when the display shows “5°C”. If you select , there is no control in terms of
temperature. Therefore, the following automatic parameter (chapter B) is
skipped. The window may be operated manually and the protection against wind
and rain is active (if set accordingly, see chapter "C. Wind alarm” and “D. Rain
alarm”).
Press in order to get to the setting of the next parameter.

11
B. Outdoor temperature block
After the setting of the indoor temperature, now select the maximum outdoor
temperature up to which the window shall remain closed.
The outdoor temperature block keeps the window closed as long as the
temperature is below the selected value. This means that in automatic mode, an
opened window is closed and not opened again if the indoor temperature value
(chapter A) is exceeded. Thus avoids energy losses during ventilation and
protects plants from cold external air.
The presetting for the outdoor temperature block is 5°C.
Adjust the value with (higher) and (lower) or select (off) in order to
switch off the outdoor temperature block. You reach the setting by pressing
once more when the display shows “-20°C”.
Press in order to access the setting of the next parameter.
C. Wind alarm
After the setting of the outdoor temperature block, now provide the value for the
wind protection function.

12
The wind alarm protects the window and furniture and fixtures from damage. If
the indicated wind value is exceeded, the window closes and the manual
operation is blocked.
Wind speed is indicated in m/sec (meters per second). The wind alarm is
maintained for 5 minutes. If the set wind value is exceeded within these 5
minutes, the stop time starts from the beginning.
The following table (see next chapter) serves as indication in order to set the
wind value. Depending on the position of the winter garden and the assembly
position of the weather station, different wind values may be optimal. Observe
the behaviour of the window in case of wind and correct the wind value
accordingly.
The presetting for the retraction in case of wind is 4 m/sec.
Adjust the value with (higher) and (lower) or select (off) in order to
deactivate the function.
Then press in order to access the setting of the next parameter.

stops flashing and the radio waves are animated (they “run”).
Now press the orange programming key inside the weather station in order to
teach in the radio connection (you can find a diagram of the circuit board in the
chapter "Preparation of the weather station”).
The learning has been successful if the LED next to the programming key shortly
flashes twice and the display skips to step 2 of the basic settings (rotational
direction of the motor).
As soon as you have confirmed (clear) with the key, the radio
connection is deleted. The display automatically skips to (learn) in order to
enable the teaching in of a new connection.

17
2. Rotational direction of the motor
After the teaching in of the radio, you may now set the rotational direction of the
motor.
If the up and down connection cables have been mixed up when connecting the
drive mechanism, this may be corrected in this step. First open the window a
little bit for the rotational direction test. Check both arrow keys and make a
setting in the display, whether the window closes again with or with .
