12.HIGH TEMPERATURE WARNING
✓ Press and hold power key " " manually for 3s till switch off, the whole appliance will stop
heating, but the cooking surface still has high temperature, the indicator digital tube of
corresponding cooking zone which stop heating will show residual heat warning symbol " ", to
indicate corresponding cooking surface high temperature.
✓ As long as the cooking zone has heated before, the high temperature warning symbol " " will
display for 35 minutes continually after the hob turn off.
✓ High temperature protection: The electronic temperature sensor on the control panel will
transmit the real-time temperature to the chip of the control panel. The control sensor starts
protection when the electronic temperature sensor gauge the current temperature is higher than
a certain value, to reduce the heating level of the cooking zone currently, and resumes the
heating level after the temperature drops.
✓ Residual heat protection: When the whole appliance stops heating, the digital tube of the
relative heating zone will display high temperature warning symbol " ", 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.
13.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, the corresponding digital
tube continues to display the high temperature warning sign " ". When the fault code appears,
please refer to the scheme in the following table to solve.

NTC.
2.short circuit of the display board
NTC.
High temperature protection on the
display board.
The communication line failure of
power supply board or display board
can cause communication anomalies.
Replace the display board first. If the
fault persists, replace the power supply
board.
Replace the power supply board.
Replace the display board
Replace the Insulated silicone strip of
circuit zona first. If the fault persists,
replace the display board.
