4.1

Press and release the MENU key and then press and release the

key or the

key to select the deep

freezing end temperature and the work set-point during deep freezing.

4.2

Press and release the

key or the

key to modify these values and then the ESCAPE key to memorise them;

these values can also be memorised through parameters r4 and r8.

Press and release the START/STOP key (1): the test to verify the correct insertion of the needle probe will be

started; see paragraph 6.14 " Test for verification of the correct insertion of the needle probe".

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 is below that established with parameter r15.

5.2

If the test is not completed successfully, the buzzer will be activated for 5 s every 60 s and the cycle will

be started with timed-control; see paragraph 6.10 "Time-controlled soft deep freezing and storage".

During the soft deep freezing phase the device displays the temperature detected by the needle probe, the cabinet

temperature, the program name (if envisioned) and the time passed since the start of deep freezing.

Operate as indicated to stop the cycle:

Press and hold the START/STOP key 3 s.

The successive parameters establish the following values:

parameter r3 establishes deep freezing soft phase end temperature.

parameter r6 establishes the maximum deep freezing duration

parameter r7 establishes the work set-point during the deep freezing soft phase.

When the temperature detected by the needle probe reaches the end temperature of the soft deep freezing phase, the

device automatically passes to deep freezing.

During deep freezing the device displays the temperature detected by the needle probe, the cabinet temperature, the

program name (if envisioned) and the time passed since the start of deep freezing.

The successive parameters establish the following values:

parameter r4 establishes the deep freezing end temperature

parameter r6 establishes the maximum deep freezing duration
