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.
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.
