COMPRESSOR DELAY
The compressor always
starts
with
a
delay cr
120
seconds from when lt last stopped.
The compressor start
delay cannol be
modmed.
The compressor, therefore, c€nnol starl
until
the delay
has
elapsed
in the
following cases (even
if the
temperature measured by
the probe
is higher than SET+DIF):
.
when the machine
is
switched
on;
.
from
when
the compressor last stopped;
.
when
the machine
is
powered again afler
an
interruption while
it
was working

CONDENSATE DISCHARGE
The eleclronic board
is
litted with a
relay
for crntrolling condensale discharge.
It
controls opening and closing
of
the solenoid valve.
The elecironic board manages the condensate discharge relay in two different ways depending on how the RLE
parameter
is set:
1.
Relay permanently energised (if
the condensate discharger is
"intelligent');
2.
Timed relay (if the condensate discharger
is "timed");
For
information on
RLE
parameler settings, please
see
paragraph 9.6
Permanently energlsed relay:
The relay conlacl remains permanently closed (relay energised)
and the
P
l
S
button has no
funclion apart from programming.
Timed relay:
The relay
is
energised every
'l
20 seconds (TOFF)
for a
time equal
to
TON seconds.
When lhe machine is switched on, the cycle will always start with the energising phase.

ACCESS TO ELECTRONIC BOARD PROGRAMMING
The
TABLE
OF
PARAMETERS indicates
all
the information relative
to
the programmable conlrol parameters.
The eleclronic board must be switched off before the programming
mode
can be accessed.
The machine remains
inadive during the programming phase.
To proorammo
a
parameter ISEE TABLE OF PARAMETERS):
Press the butlon indicated
in
the
BUTTOIVS column against the chosen parameter, power the electronic board (tum on the main swilch lG) and keep the button pressed
do\ ,n for th€
time indicated in the HOLD TIME column.
The LED conesponding to
the chosen parameter, indicated
in
lhe LED
column
of
the table, slarts flashing to conlirm the programming mode
has
been accessed (S9.7
