Operating logic with "AQUA PRIMA" filter for Primea Ring
When use of the "aqua prima" filter is selected on the user menu or via the control panel, the
system water count logic is as follows:
If the "aqua prima" function has been enabled, the electronics perform a pulse count of the
turbine, recording one pulse every 2 revolutions.
If the "aqua prima" function has been disabled, the electronics perform a pulse count of the
turbine, recording one pulse every revolution.
The graph below illustrates this function:
