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 device displays the temperature of the cabinet, the program name (if envisioned) and the time
taken to complete deep freezing successfully.
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 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.
6.8 Temperature-controlled 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:

2. Make sure that the keyboard is not locked and that no procedure is in progress.
3. Press and release the key (1), press and release the key (2) and then press and release the key (3).
The device will display the deep freezing end temperature and the work set-point during deep-freezing.
