4.1.3.2 Soft key function
Both selection buttons have a soft key function. The current
functions of the selection buttons are displayed in the bottom
display line. Depending on the selection level selected in
the menu structure, the list entry or the value, the current
function for the left- and right-hand selection buttons may be
different.
If, for instance, you press the left-hand function button, the
current function of the left function button switches from
Menu to Back.
4.1.3.3 Menu
If you press the left-hand selection button, Menu, you switch
from the basic display to selection level 1 of the menu struc-
ture.
4.1.3.4 Operating mode
If you press the right-hand selection button, Operating
mode, you access the settings directly from the basic display
under Operating mode.
4.1.3.5 Desired temperature
Depending on the operating mode, the desired temperature
may be greyed out on the basic display. This is the case, for
example, in Summer mode. As heating is not operational in
Summer mode, and therefore the heating circuit is off, there
is no desired temperature.
