This ensures that the mixer operates before the pump starts.
Stop level, mixer
The stop level must be selected so that the mixer is submerged
during operation.
Start ratio, mixer
It must be set how often the mixer is to operate before the first
pump is started.
Max. runtime, mixer
The mixer stops at the end of its set operating period (minutes or
hours).
Mix while pumping
Tick the box in this field if the mixer is to operate when a pump
operates. The mixer stops when "Stop level, mixer" or "Max.
runtime, mixer" is reached.
If the box is not ticked, the mixer starts at "Start level, mixer" and
stops again when the first pump starts.
Mix on falling level only
The mixer starts only when the water level falls. If the water level
goes up again, the mixer does not start before the start level of the
mixer is reached again.
