The electric boiler/indoor module operating mode is usually set to “auto”. It is
also possible to set the electric boiler/indoor module to “add. heat only”, when
only additional heat is used, or “manual” and then select 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, the system shows what is permitted
in the electric boiler/indoor module (crossed out = not permitted) and selectable
alternatives are presented to the right. To select which selectable functions are
to be permitted or not, mark the function using the control knob and press the
OK button.
