the

This
frequency
will
be

(
the

3
seconds).
With
a
long

for
5
seconds,
the
system
will
automatically
search
for
radio

sequentially.
Heating
system:
After
the
control
systems
are
ready
to
work,
the
heater
will
start
working
60
seconds
after
the
circulation
pump
is
activated,
unless
the
temperature
sensor
detects
that
the
set
temperature
is
lower
than
the
detected
one.
When
the
water
temperature
reaches
a
set
temperature,
the
heater
will
stop
working
automatically.
When
the
water
temperature
is
under
2°
of
the
preset
one,
the
heater
will
reactivate.
The
symbol
for
the
heater
is
located
above
the
circulation
pump
symbol
,
it
appears
as
pulsing
bubbles.
NOTE:
The
heater
will
not
be
activated
if
there
is
not
enough
water
flow.
Interlocked
system
between
the
heater
and
pumps:
Pressing
and
holding
the
ON/OFF
key
again
for
20
seconds
will
change
the
system
between
interlock
mode
or
non
‐
interlock
mode
(the
indicator
light
on
the
ON/OFF
key
shows
RED
in
interlock
mode;
while
it
shows
GREEN
in
non
‐
interlock
mode).
When
in
interlock
mode,
the
heater
will
stop
when
you
press
any
of
the
pump
and
bubble
keys.
This
feature
is
meant
to
reduce
the
power
needed
for
the
spa
so
that
it
can
match
the
power
limit
of
some
countries
(1
x
16A).
In
non
‐
interlocked
mode,
the
heater
will
keep
running
when
the
other
pumps
are
activated
unless
the
water
temperature
reaches
the
set
temperature.
NOTE!
That
requires
at
least
a
2
‐
phase
connection
if
the
total
effect
for
pumps
and
heating
exceeds
3680
W.
Temperature
sensor
self
‐
checking
system:
If
E1
is
displayed
on
the
panel,
then
the
temperature
sensor
is
disconnected.
In
this
situation
check
the
wiring
of
the
temperature
sensor
to
see
if
it’s
properly
connected.
If
E0
is
displayed
on
the
panel,
then
the
temperature
sensor
has
short
‐
circuited.
In
this
case,
the
temperature
sensor
must
be
replaced.
The
heating
system
cannot
be
activated
under
the
two
above
situations.
Water
‐
lacking
protection
system
for
circulation
pump
and
heater:
In
daily
usage,
a
blockage
of
the
filtration
medium
(cartridge
filter
or
filter
bag)
will
eventually
occur.
A
severe
blockage
will
lead
to
a
lack
of
water
for
the
filtration
pump.
Air
in
the
system
often
leads
to
the
same
problem.
For
instance,
during
startup
if
aeration
has
not
been
performed
according
to
the
instructions
in
the
manual.
When
there
is
a
lack
of
water,
the
filtration
pump
and
heater
will
stop
working
automatically.
At
this
moment,
the
symbol
of
the
filtration
pump
on
the
control
panel
will
flash
continuously,
to
remind
the
user
that
it
is
time
to
clean
or
replace
the
filtration
medium.
After
cleaning
or
replacing
the
filtration
medium,
press
ON/OFF
several
times
to
expel
the
air
inside
the
pipe
until
the
filtration
pump
works
normally.
Frost
protection
mode:
If
the
water
temperature
drops
below
10°C
and
the
circulation
pumps
pressure
switch
has
not
been
activated
(may
occur
during
filling
if
there
is
air
in
the
system),
the
system
enters
"Frost
protection
mode"
and
the
air
pump
starts.
When
Frost
protection
mode
is
activated,
no
symbols
appear
on
the
display.
NOTE!
The
system
goes
into
Frost
protection
mode
only
if
the
pressure
switch
is
not
activated.
Then
the
pump
symbol
flashes
in
the
lower
right
corner,
when
the
On/Off
button
is
pressed
the
air
pump
starts.
To
restart
the
pump,
the
power
must
be
disconnected
and
reconnected
via
the
service
switch.
When
the
pump
pressure
switch
is
activated,
the
system
will
normally
resume.
Manual
working
mode:
Turn
on
the
spa,
then
press
and
hold
the
key
for
3
seconds
to
enter

mode
(the
indicator
light
on
the
key
will
show

when
in
manual
mode,
indicator
key
3
will
light
up).
If
is
selected
the
filtration
pump
(and
thus
the
filtration)
is
on
continuously,
24h
per
day
without
stopping
in
between.
Automatic
working
mode:
Automatic
working
mode
is
on
by
default.
Press
and
hold
the
key
for
3
seconds
to
switch
over
to
automatic
mode
(The
button
will
light
up).
The
circulation
pump
starts
and
runs
for
1
hour
(the
display
panel
will
cycle
between
"ON"
and
water
temperature,
indicator
key
1
will
light
up).
After
1
hour
the
pump
will
stop
for
3
hours
(the
display
panel
will
cycle
between
"OFF"
and
water
temperature,
indicator
key
2
will
light
up).
As
long
as
the
system
is
in
automatic
mode
this
filtration
cycle
will
repeat
indefinitely.
The
keys
1,
2
and
3
(FILTER
PROGRAM)
are
non
‐
functional
keys
and
only
act
as
indicators.
