4.3 Operating concept
The operator input in the default display is described in
Section 4.3.3.
The operating concept described below applies to the
basic display (Fig. 4.2) and to the various different dis-
play/input screens of the user level.
The two dials (Fig. 4.1 Items 2 and 3 ) function according
to the Vaillant "turn and click" principle.
When turned (clockwise or anticlockwise), the dials audi-
bly engage at the next position. Each index step also
moves the cursor one position forwards or backwards in
the display.
By clicking (pressing) you can highlight or accept chang-
es to a parameter.
