Display
The WS.. has a large, easy-to-read LCD with 7 digits to display different values (e.g. energy
or flow). This new type of dynamic display enables users to identify positive flow at a glance.
Icons for previous year values and previous month values support the easy-to-understand
display concept.
1 Activity indicator at flow 4 Icon for maximum

The meter's display is subdivided into several loops.
A short press on the button (<2 s) lets the current loop pass through line by line. The first line
displays again after the last line. A long press (>3 s) displays the first line of the next loop.
The first loop is displayed again after the last loop.
