Preset
and
Scheduler
functions
for
temperature
inputs
With
MULTICAL®
603,
it
is
possible
to
program
(preset)
values
of
the
meter's
temperature
inputs.
The
primary
need
for
programmed
values
is
in
the
case
when
measuring
hot
water
energy
where
the
cold
temperature
is
required
to
be
programmed
as
it
in
practice
cannot
be
measured.
Read
more
about
application
examples
in
paragraph
7.1.
In
addition
to
programming
a
fixed
value
(preset),
it
is
also
possible
to
program
a
variable
value
that
varies
over
the
12
months
of
a
year
(Scheduler).
The
table
below
shows
which
temperature
inputs
of
which
meter
type
can
be
programmed.
Note:
The
temperature
inputs
t1
and
t2
are
the
two
legal
inputs,
which
means
that
they
cannot
be
programmed
on
an
approved
heat
meter,
cooling
meter
or
combined
heat/cooling
meter.

Differential
energy
and
volume
calculation
MULTICAL®
603
has
integrated
differential
calculation
of
energy
and
volume.
The
result
of
these
calculations
are
saved
in
the
following
four
registers:
-
dE:
difference
Energy
(E4
‐
E5
>
0)
-
cE:
control
Energy
(E4
‐
E5
<
0)
-
dV:
difference
Volume
(V1
‐
V2
>
0)
-
cV:
control
Volume
(V1
‐
V2
<
0)
All
four
registers
are
accumulated
registers
where
dE
and
dV
count
at
a
positive
difference
and
cE
and
cV
count
at
a
negative
difference.
A
reading
of
both
the
difference
and
the
control
registers
reveals
how
much
registers
have
been
counted
with
a
positive
or
negative
difference
over
a
given
period,
thus
it
is
possible
to
get
information
about
how
stable
the
system
has
been
throughout
the
selected
period.
The
calculations
follow
the
selected
integration
mode,
and
the
calculations
are
thus
carried
out
at
the
selected
integration
interval.
All
four
registers
can
be
displayed
in
the
meter's
USER
loop
and
are
saved
in
the
meter’s
loggers.
See
paragraph
3.2.4
about
display
setup
(DDD
‐
codes)
and
paragraph
3.2.10
about
possible
logger
profiles
(RR
‐
codes).
Below
is
a
calculation
example
of
the
dE
and
cE
registers
as
well
as
examples
of
display
readings.
