Section 2

14 - CHILLING PROGRAM STORAGE

The user has the button (16), which allows the saving or 

recalling of 99 chilling cycles.
To store a chilling cycle the user must:
1) set a chilling type (button 1 - 2)
2) set the mode of chilling (by temperature or by time, 

button (5))
3) set the total time or the final tempe/- buttons.
4) press and hold (long press) the “PROGRAM” button 

(16) until the beeper emits a beep; the LED of the button 

starts to flash. On the basis of the first display it will flash 

signifying waiting for setting of the first letter/number.
5) then using the keys +/- set the first letter/number and 

confirm with the button (5). This will confirm the value, 

passing on to the next one. Arriving at the ninth character 

or even before, it is possible to press the START button for 

start and storage (ATTENTION, if a program with the same 

name already exists, it will be overwritten.)
6) press START/STP (22)
With Start the software stores the “type” and “mode” of the 

chilling selected.
To discontinue saving of the program, press the storage 

button again or wait for the TimeOut (approximately 10 

seconds). If time chilling has been set, the duration set is 

stored.
In the case of temperature chilling, it will store the 

time in which the insert probe reaches the PRODUCT 

TEMPERATURE SET, and will store this time as durtion of 

chilling.
In addition, if the chilling is Positive Hard, it also saves the 

time necessary to reach the core at 68°F (20°C) (Hard).
When saving a temperature (insert probe) chilling cycle, 

the LED of the programming button flashes to indicate 

that storage of the times is in progress. As soon as the 

temperature chiling cycle ends, the LED stops flashing to 

indicate that storage has been successful.
If storing a temperature cycle, this stops (due to alarms, 

button stop, etc.), the cycle times are not saved. The initial 

settings however remain saved.

15 - CHILLING PROGRAM EXECUTION

To call up and run a memory-resident program, the user 

must: 
1) press the “PROG” button (short press), the LED lights up 

and with the +/- buttons, select one of the saved programs.
2) press START

If the save button is pressed by accident, pressing it again 

will exit that function. 
While a program is running, by pressing the “PROG” button 

the display shows the name of the program in progress.

Cause: being outside the operation range (-58°F (-50°C) 

/ 212°F (100°C)) for more than 30 seconds with a 

temperature chilling cycle in progress.
Effect: Interruption of the temperature chilling cycle in 

progress resulting in automatic start of Time chilling.

212°F (100°C)) for more than 30 seconds.
Effect: If START is given to a positive chilling (both with Time 

and Temperature) or if the latter is already in progress, it 

immediately goes into pause-work positive storage mode 

(C5 and C6 parameters0 
If START is given to a negative chilling (both with Time
