Operating
mode
changeover
There
are
2
possibilities
for
the
changeover
of
the
operating
modes:
On
the
one
hand
the
operating
modes
can
be
switched
on
by
their
1
Bit
communication
object
and
on
the
other
hand
by
a
1
Byte
object
(from
Version
1.2).
The
selection
of
the
operating
modes
by
their
1
Bit
communication
object
occurs
via
a
direct
selection
of
their
individual
communication
object.
With
consideration
of
the
adjusted
priority,
the
operating
mode,
which
was
selected
via
the
1
Bit
communication
object,
is
switched
on
or
off.
When
all
operating
modes
are
switched
off,
the
controller
changes
to
the
standby
mode.
Example:
The
priority
was
set
as
Frost/Comfort/Night/Standby.
