CoolSelect ZoneTM Panel Circuit | Samsung RS2622, RS2544, RS2666

Circuit Descriptions

10-7) CoolSelect ZoneTM Panel Circuit

1) CoolSelect ZoneTM display panel and temperature sensor

1-1) CoolSelect ZoneTM is referred to as a storage drawer to implement features of Quick cool, Thaw, and Select (Soft Freeze, Chill, and Cool).

1-2) CoolSelect ZoneTM has an additional display panel. Panel LED are off while the doors are closed. When a door is open, micro-processor senses its signal and LEDs will be on.

1-3) The basic operational principle is the same as the key scan process.

1-4) The additional sensor can measure the temperature of CoolSelect ZoneTM. This sensor enables to control the features of CoolSelect ZoneTM.

2) Damper drive circuit
