the display will show the deep freezing end temperature;
If it has been decided to start the cycle with timed-control, the display will show the duration of time-controlled
deep freezing;

Press and release the UP or DOWN key within 15 s to modify the parameter value:
5.
Press and release the START/STOP key: the LED, the
LED and the HARD LED will remain permanently
on and the test to verify the correct insertion of the needle probe will be started;
If has been decided to start the cycle with timed-control, also the will remain permanently on and the cycle
will be started with timed-control.
5.1
If the test is completed successfully, the cycle will be started.
The maximum deep freezing duration count is started on condition that the temperature detected by the
needle probe.
5.2
If the test is not completed successfully, the cycle will be started with timed-control.
During deep freezing, the display shows the residual time of the deep freezing duration and the LED
is on.
To modify the residual time, operate as indicated:
5.2.1
Press and release the UP or DOWN key again to modify the time value: the display will flash.
5.2.2
Do not operate for 4 s: the display will stop flashing and remain on permanently.
Operate as indicated to stop the cycle:
6.
Hold the START/STOP key down.

The successive parameters establish the following values:
To display the cabinet temperature, press and release the BLAST CHILLING, DEEP FREEZING or the HARD/SOFT key;
to restore the normal display, press and release the same key again or do not operate for 15 s.
If the temperature detected by the needle probe reaches the deep freezing end temperature within the maximum deep
freezing duration, it means that deep freezing has been completed successfully, the device will automatically pass to
storage and the buzzer will be activated for the period of time.
Press and release a key to silence the buzzer.
During storage, the display shows the temperature detected by the cabinet and the LED is on.
If the temperature detected by the needle probe does not reach the deep freezing end temperature within the
maximum deep freezing duration, deep freezing will not be completed successfully but will continue, the
LED will
flash and the buzzer will be activated.
Press and release a key to restore normal display and to silence the buzzer.
To display the cabinet temperature, press and release the DEEP FREEZING key; to restore the normal display, press
and release the DEEP FREEZING key again or do not operate for 15 s.
When the temperature detected by the needle probe reaches the deep freezing end temperature, the device
automatically passes to storage in the same way as illustrated previously.

Soft deep freezing and storage
The temperature-controlled soft deep freezing and storage cycle is divided into the following three phases:
-
deep freezing soft phase
-
deep freezing
-
storage
On conclusion of a phase, the device passes automatically to the next.
Operate as indicated to start the cycle:
