4.1.4.5 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.

4.2 Operating concept
The controller is operated using two selector buttons and a
rotary knob (→ Page 8).
You can use the selector buttons to
– navigate through the selection levels and the setting
level in the menu structure,
– select a setting,
– confirm a value,
– activate an operating mode,
– cancel a change to a value.
You can use the rotary knob to
– navigate through the list entries of a selection level by
turning the rotary knob to the left or right
– highlight a selection level or a setting level,
– change a selected value.
The display shows a highlighted selection level, a setting
level or a highlighted value with white font on a black back-
ground. A flashing highlighted value means that you can
change the value.
Note
If you do not operate the controller during
a period of more than 5 minutes, the basic
display appears in the display again.
