Pipe
system
When
a
divided
pipe
system
is
used,
both
operations
can
be
parameterized
individually.
Consequently
two
communication
objects
for
the
control
value
exist.
So
it
is
possible,
to
control
the
heating
process
e.g.
via
a
PI
‐
control
continuous
and
the
cooling
process
e.g.
via
a
2
‐
step
control,
because
both
processes
are
controlled
by
different
devices.
So
for
every
of
the
both
processes
are
the
settings
available,
which
are
described
from
“4.5
controller
settings”.
The
following
illustration
shows
the
setting
options
for
a
4
Pipe
system:
