1, you can press and hold the temperature zone, and then adjust the temperature of each position one by one. If it can't be opened, press and hold the unlock key for a long time to unlock it and then readjust it. In the unlocked state, press the freeze adjustment and artificial intelligence keys for 3 seconds at the same time, and the lock icon will be displayed to enter the locked state. In the case of locking, press the freeze adjustment and artificial intelligence keys for 3 seconds at the same time, the lock icon disappears and the lock is unlocked. The following settings can be made. 2. Adjustment method of thermostat knob: Generally, the thermostat knob of refrigerator has 0, 1, 2, 3, 4, 5, 6, 7. The larger the number, the lower the temperature of the freezer. Generally, we put it in the third gear in spring and autumn, depending on your requirements, whether the freezer can reach below MINUS 18 degrees. In order to keep food fresh and save electricity, you can play second or third gear in summer and fourth or fifth gear in winter. Some people may ask, the temperature is low in winter, but the temperature setting is low (the thermostat value is large), and the temperature is high in summer, but the temperature setting is high (the thermostat value is small). 3. When the ambient temperature fluctuates greatly, artificial intelligence can ensure the refrigerator to work normally by itself. According to the change of ambient temperature, the refrigerator automatically adjusts the temperature setting without manual adjustment. Press and hold the artificial intelligence button for 3 seconds, and the artificial intelligence icon will be displayed to enter the artificial intelligence state. If you exit this state artificially, press the artificial intelligence key for 3 seconds in the unlocked state, and the artificial intelligence icon will disappear. Under artificial intelligence, refrigeration, freezing temperature adjustment or quick freezing cannot be set, but the temperature of variable greenhouse can be adjusted. If you press the cold storage temperature adjustment button or the freezing temperature adjustment button, the artificial intelligence icon flashes 3 times, indicating that you are currently in the artificial intelligence state. 4. Press the refrigeration adjustment key, the refrigeration temperature icon flashes, and enter the temperature setting state of the refrigerating room. Subsequently, every time the refrigeration adjustment key is pressed, the temperature value increases by 1℃ until 10℃.

Press this key again, and the temperature will return to 2℃, and so on; If there is no key operation within 5 seconds after setting, or other key operations are performed immediately, the refrigeration temperature display area will stop flashing and confirm, and the average temperature value OF the refrigeration room will be displayed or the "of" icon will be displayed. When the "OF" gear is selected and confirmed, the refrigerating chamber is closed, and when the non-"OF" gear is selected and confirmed, the refrigerating chamber resumes cooling. 5. Press the freezing adjustment key once, and the freezing room temperature icon flashes to enter the freezing room temperature setting state. Subsequently, every time the freeze adjustment key is pressed, the temperature value will decrease by 1℃ until it reaches -26℃. Press the key again, and the temperature value will return to-16℃, and so on.
