Explanation of functions

Factory settings

Encoding switch factory setting

1	Lower position	Alarm signal function ON.
2	Lower position	Driver controller.
3	Lower position	Roller shutter/awning mode.

Manual/Automatic sliding switch
In the “MANUAL “ mode, only manual control commands and alarm signals are executed (e.g.: by pressing UP, STOP, DOWN buttons and alarm button).
When the sliding switch is set to “AUTO”, automatic control commands are carried out (e.g. control signals via group control inputs.)

Alarm signal control light
An alarm signal is a continuous switching signal at the group or individual control inputs which lasts for more than 5 seconds.
If the alarm signal control light is illuminated, this indicates an alarm signal. The encoding switch 1 can be used to switch the alarm signal function on or off.

Reset button:
Press the Reset button (with a ballpoint pen or similar object) to delete the intermediate position and the ventilation/reverse position.

POS ∇:
The Pos ∇ button can be used to programmed an intermediate position.

POS ∆:
The Pos ∆ button can be used to program a ventilation/reverse position.

Group control:
Group control refers to the simultaneous operation of several drives.

Intermediate position:
The intermediate position lies between the upper and lower limits of the roller shutters/sun protection system and can be freely selected. The roller shutters/sun protection system can be moved into this position from the upper end limit after programming. To do so, press the DOWN button twice in quick succession.
When the system is in venetian blind mode, it is also possible to programme a reverse position. In this case, this command will be automatically executed following the intermediate position command.

Ventilation/reverse:
The ventilation/reverse position lies between the upper and lower limits of the roller shutters/sun protection system and can be freely selected. Your roller shutters can be moved into this position from the lower end limit until the ventilation slats are open.
In venetian blind mode, the blind slats are turned.
To do so, press the UP button twice in quick succession.

Drive controller:
If the VarioTec device is being used as a drive controller, the drive is directly connected to the VarioTec device, in which case external signals are converted into control commands. Encoding switch 2 must be set to the lower position.

Group controller:
If the VarioTec device is being used as a group controller, additional group and drive control devices can be connected. Encoding switch 2 must be set to the upper position.

Selecting roller shutter/awning or venetian blind:
Encoding switch 3 is used to select roller shutter/awning mode (lower position) or venetian blind mode.
In venetian blind mode, the blind moves in non-maintained command mode to ensure that the slats are positioned accurately.
Press and hold any control button for more than 1 second to operate the venetian blind in maintained command mode.
