Flowmax 44i

3.2.4 General Adjustment

Reset Counter
The volume counter of Flowmax 44i can be reset.
Example of operation see appendix.
Important!
Once reset, counter values cannot be restored. After a reset the counter works
normally.
Hysteresis
The limit values can be provided with a hysteresis. This is to avoid frequent
switching of the outputs when the flow moved to a limit around.
