LOGICS
11.5.1
Thermal
protections
First
step
protection:
when
the
tank
water
goes
up
to
80°C,
the
unit
will
stop
and
the
corresponding
error
code
(E03)
will
appear
on
the
controller
display.
This
is
an
auto
‐
reset
protection.
When
tank
water
temperature
goes
down,
the
unit
can
start
again.
Second
step
of
protection:
in
case
of
first
step
failure,
when
the
water
temperature
of
the
tank
becomes
equal
or
higher
than
85°C,
the
electrical
heater
stops,
unless
the
protection
is
manually
reset.
For
the
manual
reset
of
the
protection,
remove
the
bottom
cover
and
press
the
red
button
of
reset
on
the
thermostat.
11.5.2
Disinfection
weekly
cycle
(Anti
‐
legionella)
The
unit
is
programmed
to
activate
a
weekly
anti
‐
Legionella
cycle
that
brings
the
tank
water
at
a
temperature
of
70°C.
This
system
allows
to
reduce
the
risk
due
to
bacteria
that
causes
various
diseases,
commonly
known
as
"Legionella".
It
‘s
recommended
to
read
this
paragraph
and
to
ask
explanations
to
your
installer/plant
designer
in
order
to
be
properly
informed
about
the
risk
of
spreading
this
disease.
We
strongly
advised
you
to
read
the
"Guidelines
for
prevention
and
control
of
legionnaires'
disease
‐
Approved
in
the
State
‐
Regions
Conference
of
May
7,
2015
‐
Italy
and
subsequent
amendments,
which
must
be
taken
as
a
reference
for
designing
the
plant.
The
operation
of
the
disinfection
cycle
is
as
follows:
The
heater
will
start
each
week
at
the
setting
time
(parameter
13)
automatically,
regardless
if
the
machine
is
ON
or
in
standby
mode
(i.e.
the
unit
is
off
but
remains
connected
to
the
power
supply)
When
the
upper
tank
temperature
(TS3)
becomes
higher
than
the
values
set
by
the
parameter
4
(by
default
set
at
70°C,
the
user
is
not
allowed
to
change
this
value),
the
electric
heater
stops.
When
the
previous
temperature
decreases
below
TS3
‐
1°C
and
TS3
for
the
set
disinfection
time
(parameter
5,
by
default
30
minutes
and
cannot
be
changed
by
the
user),
therefore
the
unit
quits
the
disinfection
cycle.
When
parameter
5
is
set
to
be
0,
the
disinfection
function
is
disabled
(user
cannot
set
it).
The
control
logic
program
starts
to
calculate
the
duration
of
the
cycle
when
the
temperature
of
the
water
tank
reaches
the
value
of
TS3.
The
icon
shown
below
blinks
during
the
anti
‐
legionella
cycle.
