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.
On expiry of the deep freezing duration, the device automatically passes to storage mode and the buzzer is activated
for the time period established with parameter AA.
Press and release a key to silence the buzzer.
During storage, the 3 digit display shows deep freezing duration, the 4 digit display shows the cabinet temperature
and the LED is on.
Parameter r11 establishes the work set-point during storage.
6.10 Time-controlled soft deep freezing and storage
The time-controlled soft deep freezing and storage cycle is divided into the following three phases:
- soft deep freezing phase
- 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 HARD/SOFT key: the HARD LED will switch off.
5. Press and release the TIME/TEMPERATURE key: the LED flashes and the LED will switch off.
6.1 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.
6.2 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.
6.3 Press and release the UP or DOWN key within 60 s to modify the parameter value:
7. Press and release the START/STOP key: the LED, the LED and the LED will remain permanently on
and the cycle will be started.
Operate as indicated to stop the cycle:
8. Hold the START/STOP key down for 2 s.
During the soft deep freezing phase, 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:
9. Press and release the UP or DOWN key again to modify the time value: the display will flash.
10. Do not operate for 4 s: the display will stop flashing and remain on permanently.
The successive parameters establish the following values:
- parameter r7 establishes the work set-point during the deep freezing soft phase.
- parameter r14 establishes deep freezing soft phase duration.
On expiry of the soft deep freezing phase duration, the device automatically passes to deep freezing.
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.
The successive parameters establish the following values:
- parameter r2 establishes deep freezing duration
- parameter r8 establishes the work set-point during deep freezing.
