Nowadays almost all pans are suitable for induction. You can easily test whether your old pans can also be used on induction by holding a magnet against the bottom of the pan. If the magnet stays on the pan, your old pan is suitable for induction.
Most induction hobs can be reset by disconnecting the hob from power by unplugging it from the power outlet. You will then have to wait at least 60 minutes.
A Perilex connection is a special connection that can handle more power than a normal connection. This connection has five holes instead of two and is often used for induction hobs.
