; Two-button function
With this function - only with the two-button function - values can be shifted up or down within the set

Functional principle
The "Shift value" function shifts the set datapoint type within the set limits. When the "Down" button is
pressed, the set step width is subtracted from the last value and when the "Up" button is pressed, the set
step width is added to the last value.
Lower/Upper limit
The value is shifted within these limits. The function never falls below the lower limit value and never
exceeds the upper limit value.
Step width
The step width indicates the distance between two sent telegrams. If the value 10% was sent during the
previous transmission, the value 20% is sent with the next "Up" command - with a set step width of 10%.
Repeated sending with pressed button
Repeated sending while holding down the button allows the function to increase/decrease the value until
the upper/lower limit is reached.
