Set the speed at which the heating medium pump is
to operate in the present operating mode. Select "auto"
if the speed of the heating medium pump is to be
regulated automatically (factory setting) for optimal
operation.
If "auto" is activated for heating operation, you can
also make the setting "max. allowed speed" which re-
stricts the heating medium pump and does not allow
it to run at a higher speed than the set value.
For manual operation of the heating medium pump
deactivate "auto" for the current operating mode and
set the value to between 1 and 100 % (the previously
set value for "max. allowed speed" no longer applies).
wait mode means heating or cooling operating modes
for the heating medium pump, when the heat pump
has neither a need for compressor operation nor elec-
trical addition and slows down.
5.12 - country
The country where the heat pump is installed is selected
here.
NOTE
Once you have selected country, you have 24
hours to undo the selection. Afterwards, it is
not possible to change the country selected.
