Hot
water
settings
This
menu
gives
possibility
to
set
temperatures
in
the
tanks
that
affect
the
hot
water
comfort.
Max
tank
temperature
This
setting
decides
the
set
temp
that
tank
2
will
hold
at
all
conditions.
Observe
that
higher
values
will
decrease
system
efficiency
and
possibly
make
it
impossible
for
the
heat
pumps
to
charge
the
tank.
Always
start
at
default
setting
(53C)
and
increase
later
if
higher
domestic
hot
water
temperatures
is
needed.
Min
tank
temperature
This
setting
decides
the
lowest
allowed
temperature
in
tank
1.
As
tank
1
operates
according
to
the
heating
curve
the
temperature
will
differ
dependent
on
ambient
conditions.
At
summer
time
there’s
no
or
small
heating
need
and
therefore
no
meaning
to
keep
a
high
temperature
for
the
heating
system.
However,
tank
1
is
also
used
for
pre
heating
of
the
domestic
hot
water.
This
setting
set
the
lowest
temperature
that
tank
1
will
have
at
all
conditions,
despite
the
heating
curve.
