The successive parameters establish the following values:
- parameter r4 establishes the deep freezing end temperature
- parameter r6 establishes the maximum deep freezing duration
- parameter r8 establishes the work set-point during deep freezing.
To display the cabinet work set-point during deep freezing, 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 60 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 established with parameter AA.
Press and release a key to silence the buzzer.
During storage, the 3 digit display shows the time taken to complete deep freezing successfully, the 4 digit display
shows the cabinet temperature and the LED is on.
Parameter r11 establishes the work set-point during storage.
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.
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.
6.9 Time-controlled deep freezing and storage
The time-controlled deep freezing and storage cycle is divided into the following two phases:
- deep freezing
- storage.
On conclusion of a phase, the device passes automatically to the next.
Operate as indicated to start the cycle:
1. Make sure the device is in the "on" status.
2. Make sure that the keyboard is not locked and that no procedure is in progress.
3. Press and release the DEEP FREEZING key: the LED, the LED, the LED and the HARD LED will flash.
4. Press and release the TIME/TEMPERATURE key: the LED flashes and the LED will switch off.
5.1 If parameter r19 is set at 0, the 4 digit display will show the work set-point during deep freezing; this value can
also be set via parameter r8.
5.2 If parameter r19 is set at 1, the 3 digit display will show the deep freezing duration; this value can also be set
via parameter r2.
5.3 Press and release the UP or DOWN key within 60 s to modify the parameter value:
6. Press and release the START/STOP key: the LED, the LED, the LED and the HARD LED will remain
permanently on and the cycle will be started.
Operate as indicated to stop the cycle:
7. Hold the START/STOP key down for 2 s.
During deep freezing, the 3 digit display shows the residual time of the deep freezing duration and the 4 digit display
shows the cabinet temperature.
To modify the residual time, operate as indicated:
8. Press and release the UP or DOWN key again to modify the time value: the display will flash.
9. Do not operate for 4 s: the display will stop flashing and remain on permanently.
The successive parameters establish the following values:
- parameter r2 establishes deep freezing duration
- parameter r8 establishes the work set-point during deep freezing.
