4. Configuration of the device
Please note:
When you are configuring the device and don’t press any button for more than 60 sec. the
configuration of the device will be cancelled. The changes you made will not be saved and will be lost!
Hint:
The buttons 2 and 3 are featured with a ‘roll-function‘. When pressing the button once the value will be raised
(button 2) by one or lowered (button 3) by one. When holding the button pressed for longer than 1 sec. the
value starts counting up or down, the counting speed will be raised after a short period of time.
The device also features a ‘overflow-function‘, when reaching the upper limit of the range, the device switches
to the lower limit, vice versa.
