In menu 5.3.3, you choose the climate system (2 - 8) you
wish to set. In the next menu you can make settings for
the climate system that you have selected.
If the heat pump is connected to more than one climate
system, condensation may occur in these, if they are not
intended for cooling.
To prevent condensation, check that "use in heating
mode" is checked for the climate systems that are not
intended for cooling. This means that the sub-shunts to
the extra climate systems close, when cooling operation
is activated.
Caution
This setting option only appears if "passive/act-
ive cooling 2-pipe" or "passive cooling 2-pipe"
is activated in menu 5.2.
The shunt amplification and shunt waiting time for the
different extra climate systems that are installed are also
set here.
See the accessory installation instructions for function
