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 in order to centrally operate all drive mechanisms.
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.
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.
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.

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.
D. Rain alarm After the setting of the wind alarm, now select whether the rain alarm shall be switched on or off. The rain alarm protects furniture and fixtures from damage. In case of rain, the window is automatically retracted and the manual operation is blocked. The rain message is maintained for 5 minutes.
Basic settings These are the basic settings of the device for the commissioning of the control system. The following settings are queried one after the other: 1. Radio connection to the weather station 2. Rotational direction of the motor 3. Operating direction 4.
Page 16
You may leave the basic settings at any time by pressing the key . The accomplished changes are not saved in this case. If you do not press any key in the basic settings for 5 minutes, the display automatically changes to temperature display. Accomplished settings are not saved either.
1. Radio connection to the weather station The first step is the teaching in (or later the deletion) of the radio connection. The teaching in may only be accomplished by a qualified person for electronics because the programming key is inside the weather station.
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.
3. Operating direction After the setting of the rotational direction of the motor, now select which key shall open the window. In this step, you change the allocation of the arrow keys so that they correspond with the operating direction of the window. You may directly test the setting with the arrow keys.
4 minutes or is permanently maintained as long as the alarm message exists. The permanent operating command is necessary if Arexa is used as control centre for wired motor drive units (e. g. IMSG 230) which control several drive mechanisms.
After the setting of the operating command in case of wind or rain alarm, you may now select, whether the meteorological data and the automatic commands of Arexa shall be submitted by radio to the motor control units of system XS. Leave this display at if Arexa is used as conventional single-channel control system.
6. Opening position After the setting of the sending of meteorological and automatic data, you may now teach in an opening position. You may determine an individual position for the window up to which it opens in automatic mode. Select the desired step with the key: (continue) in order to skip the setting of the opening position.
6.1. Closed position After having confirmed (learn), the command (close) appears. At first, completely close the window. Then press the key in order to access the next setting step. 6.2. Setting of the desired position The command (open) appears. Now open the window as far as the automatic shall do it later. Then press the key in order to access the next setting step.
7. Saving of basic settings At the end of basic settings, the symbol (save) asks whether the accomplished setting shall be saved. Press the key in order to save your entered data and to access the meteorological data display. With , you quit the basic settings without saving.

If cleaning and maintenance works in the environment of the awing(s) or blind(s) must be accomplished, the control system (weather station) must be switched to neutral by switching off the installed fuse and be prevented from unintentional restart. Thus you ensure that the connected drive mechanisms do not start operation.
The control must only be operated as stationary system, i.e. only in a fitted state and after completion of all installation and start-up works, and only in the environment intended for this purpose. Elsner Elektronik does not assume any liability for changes in standards after publication of this instruction manual.
Installation of weather station and connection of drive mechanism Position Select an assembly site at the building where wind, rain and sun may be collected by the sensors unobstructedly. Do not assemble any construction components above the weather station from where water may drop on to the rain sensor after it has stopped raining or snowing.

When pole mounting: curved side on pole, collar downward. An additional, optional accessory available from Elsner Elektronik is an articulated arm for flexible wall, pole or beam mounting of the weather station. Examples for the application of the hinge arm mounting: Ex.1: With the hinge arm mounting, the...
Preparation of the weather station The cover of the weather station with rain sensor is engaged at the lower rim to the right and to the left (see fig.) Remove the cover from the weather station. Be careful not to break away the cable connection between the circuit board in the bottom part and the rain sensor in the cover.
Cable connection to the rain sensor in the housing cover Connections for the drive mechanism (tension clamp, PE/N/up/down), suitable for solid conductors up to 1.5 mm² or conductors with fine wires Opening for the cable for the drive mechanism Connections for voltage supply (230 V AC, tension clamp, L1/N/PE), suitable for massive conductors of up to 1.5 mm²...
Check whether cover bottom correctly engaged! The figure illustrates the closed weather station from below. Mounting of the weather station Push the housing into the mounted holder from above. The journals of the holder must engage with the rails of the housing. If you want to remove the weather station, you must pull it out of the holder in upwards direction against the resistance of the engagement.
Installation of operating unit The operating unit is battery-powered and communicates with the weather station per radio. When you select the assembly site, please avoid direct sun because this would distort the measurements of the indoor temperature. The appropriate sensor is integrated in the lower part of the operating unit.

• Then check the function of the sensors (see next chapter). Sensor testing In case of malfunctions of the sensors, the display shows error messages instead of values. Please observe the chapter „Error messages“ on this. Sun sensor testing By the short pressing of the key on the operating unit you get to the lightness display (see chapter "Display of lightness and wind speed").
Service Service and maintenance Weather station The weather station must regularly be checked for dirt twice a year and cleaned if necessary. In case of severe dirt, the wind sensor may not work properly anymore, there might be a permanent rain message or the station may not identify the sun anymore.
Observe the correct polarity of the batteries. You need two standard batteries (1.5 V) or accumulators (1.2 V) of type AA (Mignon/ LR6). Close the housing by fitting the front panel with circuit board from above into the rear panel. The locking must engage with a clearly noticeable "click". Error messages Despite the values for temperature, lightness or wind speed, the display may indicate error messages in the meteorological data display.
