Set when the addition is to start, the minimum run time
and the minimum temperature for external addition with
shunt here. External addition with shunt is for example
a wood/oil/gas/pellet boiler.
You can set shunt valve amplification and shunt valve
waiting time.
Selecting "prioritised additional heat" uses the heat from
the external additional heat instead of the heat pump.
The shunt valve is regulated as long as heat is available,
otherwise the shunt valve is closed.

use in heating mode: If the heat pump is connected to
a climate system(s) for cooling, any condensation can
take place in this/these. Check that "use in heating
mode" has been selected for the climate system(s) that
is/are not adapted for cooling. This setting means that
the sub-shunt for the extra climate system closes when
cooling operation is activated.
use in cooling mode: Select "use in cooling mode" for
climate systems that are adapted to handle cooling. For
2-pipe cooling you can select both "use in cooling mode"
and "use in heating mode", while for 4-pipe cooling you
can only select one option.
Caution
This setting option only appears if the heat
pump is activated for cooling operation in menu
5.2.4..
mixing valve amplifier, mixing valve step delay: Here,
you set the shunt amplification and shunt waiting time
for the various extra climate systems that are installed.
Contr. pump GP10: Here, you can set the speed of the
circulation pump manually.
