The iKettle 3rd generation is designed with one button on the base that when pressed will boil the kettle.
The kettle will by default boil to 100 degrees when used manually. You can change the default temperature in product settings.
To reset the defaults manually you can hold the button on the base for 5 seconds until it beeps.
