The selection buttons have a soft key func-
tion, i.e. their function can change.
If, for example, you press the left-hand
selection button
in the basic display,
the current function switches from
(hot
water temperature) to Back.
Adjustable values flash in the display.
You must always confirm a change to a
value. Only then is the new setting saved.
The display lights up when you switch the
product on or press a button.
If you do not press any button within one
minute, the display lighting goes out.
