on,
The EASYCARD eleclronic board incorporales a
main
switch lG, a button
and
three
LED'S.
The
unit is
normally supplied with
all
its control parameters pre-sel for correcl operation (Please see
the
"FACTORY SETTINGS"
attachment
ln the
tinal
part
ol thls
manual)
The
unit
works normallv when
it is
conneded
to
the mains power supply
and
the
main
switch lG
is
dosed
(l).
The electronic board must
not
indicate any alarm signals and
not
be
in
the parameter programming mode.
ln
these conditions, the LED's and the buttons
have
lhe following funclions:
LED'S:
L1

GREEN
Power on LED, lights
up
when lhe elecironic board
is
powered;
L2 Q
GREEN
Energy saving LED, lights
up
when the compressor
is off;
L3

RED
Alarm LED, lights
up
when the de\i,-point
is
loo high
or
when there
is a
fault
in
the elecironic
board.
BUTTONS:
O
pt
=
butlon for aclivating lhe condensale discharge solenoid valve
(if
the condensale discharge
is
timed); or programming bunon
During programming operations, the above LED's and button have different funclions.
For
further information, please
see
the following paragraphs.

TEMPERATURE PROBE
The
eledronic
board features
a
lemperalure probe which is inserled
into
the thermal
mass
lo
measure
lhe
dew-point temperature in order
lo
control the thermostat (S9

)
The probe
is
protected
to
lP67 (including the cable)
and
features an
NTC
sensor with
an
operating temperature range
of
-'t
0

The resistancetemperature ratio
must
correspond to thal described
by
lhe
resistance values (rated), expressed in

STARTING THE UNIT
Afler making electrical conneclions, close

the
main
s\nitch

to slart the
unil.
LED
Ll
1,,
indicating that the board is powered, and LED L2 Q, indicsting that the crmpressor
is
ofl
both light
up
The compressor always stads aner
a
timed delay set
by
the eleclronic control (S9.4
).
lf
the unil
has
not
been used
for
a long time and if
the
HAl
alarm
(59.7.3)
is enabled, LED
L3
*
also
lights
up
(flashing) as the lemperature measured by
the
probo,
initially
equal
to ambient lemperature,
is
grealer than the
HAI
threshold
(59
7.3).
The
unit starts
working automatically according
to the
temperature measured
by
th€ prob€.
When the compressor starts,
LED
L2
Q swilches off
and
when the
HA1
threshold
is
exceeded,
LED
L3
t
switches off
as
well
lf
there
is a
voltage failure when the machine
is
workng,
the
unit
slarls automatically af,er power
is
restored.

THERMOSTAT FUNCTION
The lhermostat funclion starts and stops lhe compressor by comparing the value measured
by
the probe with
the
SET
(0'C I
32.0"F) and DIF
(4'C
/ 7.2"F) values
on
the
eleclronic board
The folloiving graph illustrates the thermoslat function operating
logic.
Vlhen the compressor
is
enabled,
it
always sterts alter
a
limed delay set
by
the eleclronic control (S9.4
).
