When the temperature measured by the pin probe reaches the chilling endpoint temperature:
- the device switches to storage mode
- the LED will continue to flash and the LED will stay on
- the display will show the message "End"
- the buzzer will sound for the period of time set by parameter AA
- press any key to mute the buzzer; press once more to cancel the message "End".
During storage:

the display shows the cabinet temperature

if chilling had a positive outcome, the LEDs and and will be on; if chilling had a negative
outcome, the LEDs and will be on and the LED will flash

the parameter r9 sets the operational set point

press several times to:
- display the message "PoS"
- exit the procedure, or leave for 15 s.
To interrupt the cycle:

press for2 seconds.
SET-TEMPERATURE NEGATIVE CHILLING AND STORAGE CYCLE
To start the cycle:

ensure the device is in "stand-by" mode and no procedures are running

press to select "nEg" and ensure the LED is flashing

press or within 15 seconds: the display will show the blast chilling end- point
temperature

press or within 15 s to change the value (the setting re- mains active until another cycle
is selected, when the value assigned by parameter r4 is restored)

press : after 2 minutes , run set-temperature negative chilling and storage cycle
Prior to starting the cycle:

the test is run in order to check correct pin probe insertion
- if the outcome of the test is positive, the cycle will be started
- if the outcome of the test is positive, the cycle will be started.
During chilling:

the display shows the temperature measured by the pin probe

the LED is on

the parameter r4 sets the chilling endpoint temperature

the parameter r6 sets the maximum chilling time duration

the parameter r8 sets the operational set point

press several times to:
- display the maximum residual chilling time remaining
- display the message "nEg"
- flashing display the cabinet temperature
- exit the procedure, or leave for 15 seconds
