The
temperature
sensor
enables
the
observation
of
the
temperature
to
switch
according
to
the
measured
temperature
the
communication
objects.
So
it
is
possible
to
switch
heatings
or
air
ventilatins
on/off
according
to
the
temperature.
The
measured
temperature
value
can
be
corrected
by
this
setting
“alignment
value
for
temperature
sensor”.
By
choosing
a
negative
value
for
this
parameter,
the
measured
value
will
be
lowered
and
by
choosing
a
positive
value,
the
measured
value
will
be
lifted.
The
value
is
multiplied
by
0,1K,
so
the
current
value
can
be
lowered
or
lifted
up
to
5K.
This
setting
is
useful,
when
the
sensor
measures
wrong
values.
When
this
function
is
activated,
the
temperature
controller
will
also
send
the
corrected
values.
All
sensors
are
matched
in
‐
plant
to
0,1K.
Two
tresholds
are
availbale
for
the
parameterization
of
the
temperature
sensor,
which
can
send
as
well
for
the
execeedance
as
for
the
undercut
switching
telegrams.
These
are
done
by
the
communication
objects
“Status
of
threshold
value
1”
and
“Status
of
threshold
value
2”.
The
evaluation
of
the
tresholds
can
also
be
done
cyclic.
The
communication
objetcs
of
the
temperature
sensor
are
