4.4 Ice cream hardening
Pressing this area enables selection of an ice cream
hardening cycle.
This is a time controlled blast-freezing cycle with the set point
provided by parameter r8 and the duration by parameter r24. At
the end of the time set by r24, there is no move to a conservation
phase, the hardening cycle continues until the key
is pressed.
If the door is opened the time count stops and restarts when the
door is closed.
4.5 Cabinet sterilisation
Pressing this area enables selection of a
sterilisation cycle.
This function can be activated by parameter and can only be used
if u1=1. If the needle probe heating function has also been
enabled, the sterilisation icon is shown if the temperature recorded
by the needle probe is above 0°C .
The cabinet door must be closed to start up a sterilisation cycle.
Pressing the key starts up the sterilisation cycle.
Sterilisation ends when the time set by parameter u6 has elapsed,
after the key has been pressed or if the door is
opened.
During sterilisation the cabinet sterilisation relay is active. If
parameter u11 is set to 1, the evaporator fans are also active. If
the fans are run at variable speeds, there will be 100% ventilation
during sterilisation.
The display will show the count-down for the remaining time. At
the end of the cycle the buzzer sounds and the screen returns to
the Home screen.
