the cooking zone currently, and resumes the heating level after the temperature
drops.
✓ Residual heat protection: When the whole appliance stops heating, the indicator
light of the relative cooking zone will display, indicating that cooking surface
temperature is too high, please do not touch to avoid getting burned.
✓ Safety cut-off protection:For the models with plug,when cut off after 1S at any
time,the voltage between L/N of the plug should fall to below safe voltage range.
10. PCB board fault codes and solutions
When a PCB board failure occurs, the timer digital tubes on the display panel always
display the fault code, and all the burners that are being heated stop heating, and
automatically return to the shutdown state after 1 minute. For the burners that have
been worked, their indicator light continue to display slowly (display 1 time per
second) , indicating that cooking surface temperature is too high. When the fault code
appears, please refer to the scheme in the following table to solve.
How to use the hot plate
