[f] FREEZE COMPLETION CONTROL
1) The target integrated values (cube control thermistor temperature and freeze cycle
time) are set for freeze completion.
* The target integrated freeze completion temperature and time are adjustable in the
maintenance mode (see “3. [b] MAINTENANCE MODE”).
2) After the cube control thermistor senses a temperature below 0°C, the cube control
thermistor temperature and freeze cycle time are integrated every second.
3) When the integrated values reach the target, the freeze cycle completes.

As the previous freeze completion control depended on the freeze completion
temperature only, the dimple size varied in 1) spring/fall, 2) summer, and 3) winter even
at the same freeze completion temperature.
For example, when the freeze completion temperature is -18°C and the dimple size is
5 mm, the freeze cycle time becomes longer and dimple size smaller in summer, and
the freeze cycle time becomes shorter and dimple size larger in winter.
