Metered immediate:
The controller monitors the volume of water used. As soon as the capacity is
exhausted, the controller starts the regeneration process.
Metered delayed:
The controller monitors the volume of water used. When the remaining capacity is less
than the programmed reserve, the controller queues a regeneration that will start at
the programmed regeneration time.
Time clock:
The controller initiates the regeneration at regular preset time interval at the
programmed regeneration time.
