max step
Setting range (binary stepping deactivated): 0 – 3
Setting range (binary stepping activated): 0 – 7
Default value: 3
fuse size
Setting range: 1 - 200 A
Factory setting: 16 A
transformation ratio
Setting range: 300 - 3000

Select this option if the step controlled additional heat
is connected and is positioned before or after the revers-

additional heat is for example an external electric boiler.
When binary stepping is deactivated (off), the settings
refer to linear stepping.
Here, you can set the maximum number of permitted
additional heat steps, whether there is internal additional
heat in the tank (only accessible if the additional heat is
positioned after the reversing valve for hot water char-
ging (QN10)), whether binary stepping is to be used, the
size of the fuse and the transformer ratio.
TIP
In order to select location before or after QN10,
you need to tick "hot water production" in menu
5.2.4 - accessories and add a docking in menu
5.2.3 - docking. (Only one air/water heat pump
in the system applies for this option.)
