BOSCH PKN645FP2E

What is the difference between flexi, combi zone, and round inductors?
Round zones have a fixed size. A combi zone bridges two separate zones into one larger area. A flexi zone, on the other hand, adapts to the shape and size of the cookware anywhere on the surface.

Can I connect the hob to 400V?
Yes, most induction hobs can be connected to 400V (two phases), which is actually recommended for reaching full power.

Why can't I connect a hob with a power input of 4.6 kW to two phases?
A 4.6 kW power input is designed to run on a single, stronger phase. Splitting the load across two phases usually requires a higher total power rating, around 7 kW.

On your website, you state Voltage 220-240 V, can the hob be connected to a multi-phase connection?
Yes, the 220-240V figure refers to the voltage per phase. The hob can typically be connected to two phases (400V) as well.

Which hobs are designed for flush installation?
These are frameless models with polished edges, listed in the range as suitable for flush-mount installation.

The hob is noisy, it clicks loudly.
The clicking comes from switching relays or the power management function. It's a normal operating characteristic of induction technology, not a fault.

Is it possible to turn off the sound signals on the hob?
Yes, on Bosch and Siemens models this can be done in the "Basic Settings" menu (C2). Confirmation tones can be muted, but warning signals stay active regardless.

What is the smallest diameter of cookware that will work on an induction hob?
The minimum diameter depends on the size of the zone, and typically falls somewhere between 9 and 12 cm.
