Setting range: 0.1 – 10.0
Default value: 1.0
mixing valve step delay
Setting range: 10 – 300 s
Default values: 30 s
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.

start delta-T, stop delta-T: Here you can set the temper-
ature difference between solar panel and solar tank at
which the circulation pump is to start and stop.
max. tank temperature, max. solar collector temp.:
Here you can set the maximum temperatures in tank
respectively solar panel at which the circulation pump
is to stop. This is to protect against excess temperatures
in the solar tank.
If the unit has an anti-freeze function and/or solar panel
cooling you can activate them here. When the function
has been activated, you can make settings for them.
freeze protection
anti-freeze temperature: Here you can set the temper-
ature in the solar panel at which the circulation pump is
to start to prevent freezing.
solar panel cooling
start solar collector cooling: If the temperature in the
solar panel is greater than this setting at the same time
that the temperature in the solar tank is greater than
the set maximum temperature, the external function for
cooling is activated.
