Switch on
When the display switches on it performs a lamp-test (flashing of
all segments and dots for 5 seconds).
When switched on for the first time, the display is in stand-by mode
(three horizontal dashes “---” are shown on the display, one for each
digit). The next time it is switched on, or when the power supply
is restored, the blast chiller status varies depending on its status
befo
re the power supply failure.
If there is no program running, activate standby mode by press-
ing and holding
SEL
for 4 seconds.
Important information
The display shows programs for managing the following blast
chiller functions:
positive blast chilling
or cooling (automatic or manual),
negative blast chilling
or freezing (automatic or manual)
+
For automatic programs, the reference value is the tem-
perature detected by the needle probe.
For manual programs, the reference value is the time.
Both the automatic program and the manual program include
a blast chilling cycle, automatically followed by a storage phase,
which is positive or negative depending on the cycle chosen.
At the end of the blast chilling cycle, when the storage phase
starts automatically, a buzzer sounds intermittently (this can be
modified by the user under parameter P 0).
To silence the buzzer in advance, press the DOWN key.
During the execution of a program:
- the
LED L2
is off if a positive blast chilling cycle was selected,
or is on if a negative blast chilling cycle was selected;
- the
L3 LED
is on during the blast chilling cycle and flashing
during the storage phase;
- pressing the
UP
key determines the display of the temperature
measured by the cell probe for a duration of 5 seconds;
- press ing and holding the
SET
key determines, until the key is
released, the display of the time elapsed since the start of the
blast chilling cycle if the blast chilling cycle is still in progress,
the duration of the previous blast chilling cycle if the storage
phase is in progress.
At the end of a program, before starting the next program, the
display shows the data relative to the last program run.
Automatic program
To select and start an automatic program (Fig. 8 on page 18), pro-
ceed as described below:
- Pr es s the SEL key until the display shows the
positive blast
chilling
cycle (d3°C - P13 parameter) or
negative
blast chilling
cycle (default -18 °C - P14 parameter).
-
+
The repeated pressing of the SEL key causes the display
to alternately flash between the value set for the posi-
tive blast chilling cycle and the value set for the nega-
tive blast chilling cycle.
- Wait 5 seconds or press the
SET
key to confirm (the tempera-
ture display becomes fixed).
- Press th e
SET
key to start the program: during the execution
of an automatic program the display shows the temperature
measured by the needle probe.
+
The temperature parameters can be modified by the
User.

STARTING
At the end of the blast chilling cycle the display shows the tem-
perature measured by the needle probe, flashing if the target set
has not been reached (P13 -P14
parameters ).
The duration of the blast chilling cycle is determined by one of
the following conditions:
- rea
ching the selected temperature setpoint (P13 -P14 parame-
ters ) ;
- exceeding the set time, even if the temperature has not been
reached (parameters P19-P20) .
At the end of the blast chilling cycle, the
storage
phase starts
(signalled by a beep). The temperature measured by the cell
probe is shown on the display.
Storage phase characteristics:
- a fter a positive blast chilling cycle (parameter P19) room tem-
perature setting equal to the value set for parameter P17;
- after a negative blast chilling cycle (parameter P20) room
temperature setting equal to the value set for parameter P18.
Manual program (by time)
To select and start a manual program (Fig. 9 on page 20) proceed
as described below:
- pr
es s the
SEL
key until the display shows the
positive blast
chilling cycle
(display of P13 parameter, d3 °C) or nega-
tive blast chilling cycle (display of P14 parameter, default -18 °C).
+
The repeated pressing of the SEL key causes the display
to alternately flash between the value set for the posi-
tive blast chilling cycle and the value set for the nega-
tive blast chilling cycle.
- Wait 5 seconds or press the
SET
key to confirm (the tempera-
ture display becomes fixed).
