Heat
curve
point
A
There
are
3
basic
settings
for
the
heating
curve,
points
A,
B
and
C.
With
these
3
points,
you
can
adjust
the
gradient
and
vertical
position.
The
aim
is
always
to
set
the
curve
as
low
as
possible.
Point
A
describes
the
temperature
of
the
water
to
be
sent
to
the
heating
system
if
the
outdoor
temperature
is
‐
15
°
C.
The
factory
default
setting
for
this
item
is
55
°
C.
In
other
words,
when
it
is
‐
15°C
outside,
the
mixing
valve
open
in
order
to
transmit
55
°
C
hot
water
to
the
heating
system.
When
you
adjust
this
point,
you
change
the
angle
of
the
entire
heating
curve.
The
biggest
changes
occur
when
outdoor
temperatures
are
cold
‐
see
the
graph
below.

point
A
on
the

factory
default
setting

is
marked
with
a
cross)
