Troubleshooting
MULTICAL
403
has
been
constructed
with
a
view
to
quick
and
simple
installation
as
well
as
long
and
reliable
operation
at
the
heat
consumer.
Should
you,
however,
experience
an
operating
problem,
the
table
below
can
be
used
for
troubleshooting.
Should
it
be
necessary
to
repair
the
meter,
we
recommend
only
to
replace
battery,
temperature
sensors
and
communication
modules.
Alternatively,
the
whole
meter
should
be
replaced.
Major
repairs
must
be
made
by
Kamstrup
A/S.
Before
sending
us
a
meter
to
be
repaired
or
checked,
please
use
the
error
detection
table
below
to
help
you
clarify
the
possible
cause
of
the
