3、 Requirements for electronic control system

1. Display function:

(1) Four yellow/red digital displays, with a display range of -40 ℃ to 50 ℃/-40 ℉ to 104 ℉; When the temperature inside the box is below -40 ℃ (-40 ℉),it displays -40 ℃ (-40 ℉); When the temperature inside the box is above 50 ℃ (104 ℉),it displays 50 ℃ (104 ℉).

(2) After the refrigerator is powered on, the power indicator light shows red, and the compressor on indicator light shows green.

2. Temperature display accuracy: ± 1 ℃, ± 2 ℉

3. Control temperature (shutdown temperature) adjustment: Short press the set button to display the control temperature, then press the △ or ▽ button to change the value and memorize it. If no key is pressed, the temperature inside the display box will be restored after 3 seconds.

4. Switching LED lights: Short press the ON/OFF button to turn on or off the LED lights.

5. Power on/off: Press the ON/OFF button for 3 seconds to turn off the cooling mode. If there is no display on the digital display, stop all control outputs. Press the ON/OFF button again for 1 second to display the measured temperature. After a delay, start the cooling mode.

6. The three level switch selects the battery protection voltage, as shown in the table below.
