The controller is operated by three pushbuttons below the
display. Button 1 is for scrolling forwards through the menu
options or for increasing the adjustment values. Button 2
performs the opposite function.
Button 3 is for the adjustment of individual parameters.
By pressing button 3 you will get to the next submenu or
the SET-mode. It is also used for the confirmation of the
adjustments made.
In order to get to the main menu the backward button
has to be set to „back" and has to be confirmed with the
SET/OK button. If no button has been pressed for more
than 60 seconds, the controller is automatically set back to
the main menu.
Important notice: The selectable values and options are
function-dependant and will only appear on the display if they
are available for the adjusted start parameter and activated
via the operation code.
Operator code: Expert-Code 119
The expert menu is accessible after entering the operator
code, here the values can be changed.
