6. 5 major safety protection, heater fault protection, temperature sensor protection, dry burn protection, water shortage protection, communication fault protection;
7. Software evaluation level B: for the control system with protective electronic circuit, the software can prevent the danger caused by non software fault.
Performance & function introduction
Menu function: you can choose the menu mode function of the steamer, or you can set the best heating mode and time of the food by yourself to store it. Next time the machine is started, the menu program can be used for processing.
Child lock function: prevent misoperation;
Fault alarm function: stop the machine for alarm after the fault occurs, and display the fault code to ensure the safety of human and machine;
Timing and clock function: preset time selection of steamer mode.
