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.
Remote regen start:
The controller initiates the regeneration when an external dry signal is acquired on the S2
terminal (see Electrical connections [
