Simple operation instructions

Temperature control range: -20℃-20℃ (-4℉∽68℉)
Temperature display range: -30℃-40℃ (-22℉∽104℉)
Standard voltage input range: DC12V/24V, up to DC30V

1. Open and close the refrigerator: Connect the correct DC12/24V power supply. If the refrigerator is in the standby state, the “OFF” symbol will appear in the middle of the display after the refrigerator self-test is completed. At this time, you need to press and hold the “Power button” for 3 seconds to complete the startup. After the refrigerator is turned on, the display will show the current temperature and working mode of the refrigerator. After waiting for the power-on delay (the factory default is 1 minute), the refrigerator enters the working mode, and the compressor starts to work to cool down. To turn off the refrigerator, press and hold the “Power button” for 3 seconds while the keyboard is unlocked.
2. Refrigerator keyboard locking and unlocking operations: For example, when the keyboard is locked (the child lock icon is on in the lower right corner of the display screen), long press the “UP/DOWN” button for 3 seconds to unlock, and the child lock icon will not light up, and the keyboard will be locked automatically if there is no operation for 30 seconds.
3. Compressor working mode setting: In the unlocked state of the keyboard, press the “Set button” to freely switch the compressor working mode “ECO/MAX”, if you need to quickly cool down to a lower temperature, switch to “MAX” mode, if you only need to refrigerate or keep warm, you can set the It is set to “ECO” mode to save energy.
4. Low voltage protection function setting: This product has a low voltage protection function. When it detects that the battery voltage is lower than the set value, it will automatically turn off the compressor to prevent over-discharge from damaging the battery or causing the car to fail to start normally. At this time, the “EI” code prompt will be displayed on the display screen, such as 1 minute after the voltage returns to normal, the refrigerator will automatically enter the working state. The factory default is “Mid-Range”, if you need to change it, follow the steps below: Unlock the keyboard Press and hold the “Set button” for 3 seconds, release it after hearing the “di” sound of the buzzer, and then briefly press the “Set button” again, and one of the battery protection level icons “L, M, H” on the display will flash. Display and then press the “UP/DOWN” to change the setting. Refer to the following table for specific values: a： b:
   battery protection| 12V disconnect| 12V start| 24V| 24V start
   ---|---|---|---|---
   L| 9.6 V| 10.9 V| 21.3 V| 22.7 V
   M| 10. 4 V| 11. 7 V| 22.8 V| 24.2 V
   H| 11.1 V| 12.4 V| 24.3 V| 25.7 V

Note: If your refrigerator enters battery protection early, it is likely that the low voltage protection value is set too high due to insufficient power supply voltage. Or your DC power supply is wired incorrectly and cannot provide enough current. Check whether the power wiring is suitable, and consider lowering the battery protection gear appropriately. In order to ensure that the car can be started normally, it is recommended to set the protection level to “H” when using the refrigerator in the car.

5. Refrigerator temperature setting operation: In the unlocked state of the keyboard, the temperature settings of the L temperature zone and the R temperature zone can be set by pressing the “Set button”, and then the “UP/DOWN button” can be used to adjust the temperature rise or fall of the refrigerator (a group of temperature values on the display screen flashes to display the current setting value, the temperature rises or falls by 1 degree each time), if you press and hold it, you can quickly adjust to the required temperature value, if there is no change within 5 seconds, the set value will be automatically saved.
6. Refrigerator L temperature zone and R temperature zone close setting operation: (L and R temperature zones cannot be closed at the same time) In the unlocked state, when setting the temperature, press the “Set button” to switch,the L temperature zone and the R temperature zone will flash, if the L temperature zone is flashing, press the “power button” at this time, the L temperature zone will be turned off, and “OFF” will be displayed. Press the “power button” again to switch to the normal temperature value display. Press “SET” again, the R temperature zone flashes, press the “Power button” at this time, the R temperature zone is turned off, the display “OFF” is turned off and then press the “Power button” to turn to the normal temperature value display.
