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.

The basic position of the operating unit of the control system displays the
current outdoor temperature (upper line) and the indoor temperature (lower line)
as well as the function mode (automatic or manual), the battery load and the
current alarm messages for rain or wind. The meteorological data are updated
once per minute (and in case of a keystroke).

Automatic mode activated
Manual mode activated. The connected drive mechanism was
operated manually (with arrow keys) or key was pressed. Thus,
the automatic functions are deactivated, there is no control in terms
of temperature. The safety functions rain alarm and wind alarm are
still activated. The control is in manual mode until you change to
automatic mode with key.
Rain alarm. The window is closed, manual operation is blocked. The
rain protection function may be turned on and off in the automatic
settings.
Wind alarm. The window is closed, manual operation is blocked.
The wind protection function may be set up or turned off in the
automatic settings.
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
automatic (display ).
If the sending of meteorological data and automatic commands has been
activated (see chapter 5 of the basic settings), you additionally obtain the
following display after the manual mode:

8
In order to get to the display, press key twice shortly in automatic mode ( )
and once shortly in manual mode ( ).
As long as the display shows , manual operating commands of this
operating unit are submitted to all drive mechanisms in system XS. During this
display, use the keys , and in order to centrally operate all drive
mechanisms.
With the SET key and by pressing shortly, you access the display of lightness
and wind speed.
By pressing long, you access the setting menu of the automatic and the basic
setting. For this purpose, please read chapters “Setting of automatic” or „Basic
settings“.

Setting of automatic
For an optimal aeration, the values for automatic operation must be adjusted to
the local conditions. The following settings are queried one after the other:
A. Indoor temperature for opening
B. Outdoor temperature block
C. Wind alarm
D. Rain alarm
E. Storage
This is how you access the automatic settings:
In meteorological data display, press the key for at least 3
seconds in order to access the automatic setting.
You are in the automatic settings as soon as the symbols and are shown
left in the display. You can see the first parameter (lightness) which must be set.
