Here you set the start and stop temperature of the hot
water for the different comfort options in menu 2.2 as
well as the stop temperature for periodic increase in
menu 2.9.1.
For a higher charge output click the high output selec-
tion.
With "high power" activated, the hot water is charged
at a higher output than in the standard mode and thus
gives a higher hot water capacity.
Menu 5.1.2 - max flow line temperature
climate system
Setting range: 5-70 °C
Default value: 60 °C
Set the maximum supply temperature for the climate
system here. If the installation has more than one climate
system, individual maximum supply temperatures can
be set for each system. Climate systems 2 - 8 cannot be
set to a higher max supply temperature than climate
system 1.

Here you set the maximum permitted difference
between the calculated and actual supply temperature
during compressor respectively add. heat mode. Max
diff. additional heat can never exceed max diff. com-
pressor

When the current supply temperature deviates from
the set value compared to that calculated, the heat pump
is forced to stop irrespective of the degree-minute value.
If the current supply temperature exceeds the calculated
flow with set value, the degree minute value is set to 0.
The compressor in the heat pump stops when there is
only a heating demand.
max diff addition
If "addition" is selected and activated in menu 4.2 and
the present supply temp exceeds the calculated with
set value, the additional heat is forced to stop.
Menu 5.1.4 - alarm actions
Select how you want the heat pump to alert you that
there is an alarm in the display here.
The different alternatives are that the heat pump stops
producing hot water (default setting) and/or reduces
the room temperature.
Caution
If no alarm action is selected, it can result in
higher energy consumption in the event of an
alarm.
