The heat pump operating mode is usually set to "auto". It is also possible to set
the heat pump to "add. heat only", but only when an addition is used, or "manual"
and select yourself what functions are to be permitted.
Change the operating mode by marking the desired mode and pressing the OK
button. When an operating mode is selected, it shows what is permitted in the
heat pump (crossed out = not permitted) and selectable alternatives to the right.
To select selectable functions that are permitted or not, mark the function using
the control knob and press the OK button.
