All ARISTON glass-ceramic hobs have this function, which locks off the Touch Controls. Indispensable when small kids are around, it stops your settings being inadvertently altered.
The residual heat leds on all ARISTON glass-ceramic hobs warn you that the cooking zone is still hot even though the hob is switched off. These leds turn off when the temperature drops below 60° C.
