How do I set the temperature?
From the home screen, tap the Action button on the Nomiku to start the water circulation, and then turn the knob to change the setpoint temperature (the target temperature that you want the water to reach). The Nomiku was automatically save the temperature that you set it to, and will begin heating the Nomiku to that temperature.
If the temperature isn't changing, make sure the setpoint temperature is highlighted, not the timer. Press the right action button to exit the timer menu if you are in it.
