The Anova app is the best way to help you cook like a pro, but you can set the temperature directly on your Anova Precision Cooker Nano.
Select the Target Temp icon located on the top middle of the display.
Press + or - buttons until desired temperature is selected.
Press the Start button located between + and - buttons to initiate a cook.
Front light indicator will fade until desired temperature is achieved. Once temperature is achieved the light indicator will turn solid.
