fluid
(B/W

This
setting
makes
it
possible
to
set
the
lowest
permitted
temperature
on
the
brine
fluid.
If
the
temperature
(measured
on
brine

gets
below

PI
‐
regulator
settings
for
charge
pump
The
charge
pump
operates
with
variable
speed
dependent
on
requested
flow
temperature.
The
control
is
achieved
with
a
software
PI
‐
regulator.
It
might
in
some
cases
be
necessary
to
adjust
the
parameters
of
the
regulator
depending
on
the
hydraulic
installation.
There
are
3
different
settings
available,
see
below.

Increased
values
will
fasten

but
can
result
in
overshooting
and
possible
high
