How do I use set formula mode?

To set formula mode for in app use, first find formula mode by:

  1. Selecting the network
  2. Select the iKettle
  3. Select features (top right of the screen)
  4. Select “formula mode”

When you are in formula mode, the first option is to enable formula mode. Once enabled, there will be two temperatures to set, “heat to” and “cool to”.  Select the temperature you wish the kettle to boil to by selecting “heat to” and selecting the temperature you wish to be notified that the water has cooled to.

The “cool to”, will be the default “cool to” temperature when you open the app.

Simply select “start” and the kettle will boil to your “heat to” temperature cool down to your “cool to” temperature and notify you.

You can change the “cool to” temperature, by changing the dial to the desired temperature when formula mode is enabled. The app will then ask you to adjust your “cool to” temperature.
