This document is a user manual for the Smeg SI1M7643B induction hob. It provides comprehensive information on safety, installation, operation, maintenance, and technical specifications.

Function Description

The Smeg SI1M7643B is a built-in induction hob designed for cooking purposes. It features four induction cooking zones and a control panel with sensor fields for operation. The hob utilizes induction technology, which generates heat directly in the bottom of the cookware, leading to efficient and fast cooking.

Key functions include:

Heat Setting: Allows users to set and adjust the heat intensity for each cooking zone using a control bar.
MultiZone: Connects two left-side cooking zones to operate as one, ideal for larger cookware.
Accelerator: Activates a desired heat setting in a shorter time by initially operating at the highest setting.
Power Function: Provides additional power to induction cooking zones for a limited period, useful for rapid heating.
Timer: Includes a Count Down Timer for setting specific cooking durations and a CountUp Timer for monitoring cooking time. A Minute Minder function is also available.
Pause: Sets all operating cooking zones to the lowest heat setting and locks other control panel symbols.
Lock / Child Safety Device: Prevents accidental operation of the hob and locks the control panel during cooking.
Auto-Vent: An advanced automatic function that connects the hob to a special hood via infrared signals, automatically adjusting fan speed based on cooking mode and cookware temperature. Manual fan speed adjustment is also possible.
Eco-Heat (3-step Residual heat indicator): Shows the level of residual heat, allowing for continued cooking or keeping food warm.
Automatic Switch Off: Deactivates the hob automatically under certain conditions, such as no heat setting after activation, spills on the control panel, overheating, or incorrect cookware.
OffSound Control: Allows deactivation or activation of the hob's operational sounds.
Power Limitation: Enables users to decrease or increase the hob's overall power level, which is useful for adapting to house installation fuses and managing electricity loading.
Eco-Logic: Manages power distribution between cooking zones, especially when total electricity loading exceeds 3600 W on a single phase, by reducing power to other zones.
