the arrow keys. If no key is pressed for a few seconds, the display switches back to measuring mode.
If you hold down the respective arrow key for a few seconds, the display starts to run faster.
After tapping the SET button again, the display goes to the setting for the control accuracy and saves the
previously entered value. Use the arrow keys to set the desired value in 1 °C steps. If you press the SET button
again, the unit goes to the alarm value.

also set with the arrow keys. The entered values are saved as soon as no button is pressed for a few seconds.
