2-6-3. OptiChill Temperature Control
1. The Optichill is in the bottom of the refrigerator compartment and allows the user to select and adjust the temperature
based on the type food stored there. Selections include meat, fish, fruits and vegetables, etc. Storing foods at the proper
temperature allows them to be stored for longer periods.
2. The Optichill consists of a temperature sensor, a damper between the Optichill and the freezer, and a temperature
control/display at the top.
3. At initial power-up, the Optichill defaults to FRUIT VEGE. If the refrigerator door is opened, the Optichill LED will be on.
4. When you press the SELECT button on the left, the LED will light and indicate the setting. The time for the selected
function will be shown. You can cycle through the options in this order: FRUIT VEGE (4°C)
→
CHILLED ROOM
→
PARTIAL
FREEZING
→
FRUIT VEGE. The display will indicate the temperature for the selected setting.
5. The Optichill sensor detects the temperature and relays that information to the MICOM. When the set temperature is
reached, the Optichill damper is closed. If the temperature rises, the damper is opened to allow the temperature to fall
again.
6. If the Optichill damper hasn’t moved within an hour, it is automatically moved and returned to its original setting once
every hour to keep it from freezing in one position.
