If
the
unit
is
in
standby
mode
(and
also
if
ON/OFF
contact
is
opened),
the
disinfection
occurs
with
the
same
control
logic
in
case
of
the
unit
is
in
operation.
If
the
unit
is
disconnected
from
the
power
supply,
the
disinfection
cycle
will
not
occure.
If
the
unit
is
left
without
power
supply
for
longtime,
DO
NOT
use
the
water
contained
inside.
It
is
recommended
to
emplty
the
tank
and
the
water
contained
inside
the
pipes
of
the
DHW
system.
It
is
also
recommended
that
you
let
the
water
flowing
for
enough
time
across
the
pipes
not
only
for
renewing
all
the
water
but
also
for
washing
the
pipes
themselves.
This
required
"washing"
time
is
inversely
proportional
to
the
temperature
of
the
water
flowing
in
the
pipes.
After
cleaning
and
renewing
all
the
water
contained
inside
the
unit
and
in
the
pipes
of
the
system,
you
should
proceed
with
a
disinfection.
The
disinfection
cycle
happens
only
in
water
tank.
Therefore,
it’s
recommended
to
perform
a
recirculation
of
the
water
system
especially
for
disinfecting
all
the
contained
water.
If
cannot
be
possible,
according
to
the
preceding
warning,
it
is
recommended
to
let
the
water
system
to
flow
for
a
enough
for
cleaning
the
pipes
and
renewing
the
water.
If
the
parameter
5
is
set
to
be
0,
the
disinfection
function
is
disabled.
Such
operation
is
strictly
unrecommended;
the
manufacturer
declines
any
responsibility
for
the
data
caused
by
a
lack
or
incorrect
unit
disinfection.
If
you
desire
to
disable
the
disinfection
cycle,
you
should
ask
the
maintainer
about
the
consequences
that
may
arise
from
this
operation
It
is
strictly
forbiden
to
change
the
default
value
of
parameter
4.
The
parameters
4
and
5
control
the
anti
‐
legionella
cycle
(temperature
versus
time).
We
recommend
to
respect
the
above
guidelines,
if
you
want
to
change
them.
Please
remember
that
to
keep
the
temperature
of
the
tank
water
between
55
‐
60°C
in
order
to
inhibit
the
bacterial
proliferation
(see
Annex
13
of
the
guidelines
mentioned
above).
The
plant
designer
must
keep
in
mind
the
legionella
risk
and
should
adopt
all
the
measures
for
prevention
and
control
of
water.
The
user
is
RESPONSIBLE
to
periodically
check
the
correct
operation
of
the
anti
‐
legionella
cycle
and
to
verify
that
during
the
disinfection,
the
setting
temperature
parameter
is
put
to
be
4
and
is
reached
for
the
duration
indicated
by
the
parameter
5.
11.5.3
ON/OFF
contact
When
ON/OFF
contact
is
closed,
and
the
controller
is
ON,
the
unit
can
work
and
the
running
mode
is
decided
by
the
setting
of
the
controller.
When
ON/OFF
contact
is
closed,
but
the
controller
is
OFF,
the
unit
can’t
work.
When
ON/OFF
contact
is
opened,
but
the
controller
is
ON,
the
unit
can’t
work.
If
the
controller
is
ON,
and
the
ON/OFF
status
is
changed
from
opened
to
closed,
the
unit
will
work
by
the
previous
settings
of
the
controller
(auto
‐
restart).
If
the
unit
was
previously
in
stand
‐
by,
in
case
the
ON/OFF
status
is
changed
from
opened
to
closed,
the
unit
remains
in
stand
‐
by.
For
setting
the
signal
remotely,
the
parameter
17
must
be
adjusted
to
be
0
(default).
The
temperature
setting
is
depending
on
the
parameter
20:
-
P.20
=
0
(default),
the
temperature
value
introduced
manually
is
compared
with
the
maximum
admissible
temperature
value
given
by
the
climatic
curve
(which
is
eventually
corrected
by
the
compensation
parameter
P.19),
and
then
the
unit
will
operate
according
to
the
lowest
one
of
the
comparison
between
both
values.
-
P.20
=
1,
the
setting
temperature
will
be
the
same
as
the
one
introduced
manually
on
the
unit.
