General information
SFE-EV-VIRIDION can grant significantly water savings during slow rinse and fast rinse phases.
The Viridion functionality is totally transparent for the user, it is activated automatically plugging
probe K-10058, no other settings are required.
At the beginning of the backwash phase, controller checks conductivity (C
through the drain of the valve and stores this information.
During the brine draw, the slow rinse and fast rinse controller compares the instantaneous
conductivity in the water (C
measured value (C
) is in a range in between C
j
passed by the resin bed.
When this condition happens, controller executes the following operations:
1. If the condition happens during a fast rinse, controller ends the rinse and returns in service
status.
2. If the saving happens during a slow rinse, controller switch to a fast rinse. In this case fast rinse
duration is 20% of the programmed time for a full fast rinse operation (minimum duration is
1 minute).
•
In battery-operated mode, regeneration is not carried out and the parameters cannot be edited;
•
the SFE-EV-VIRIDION controller allows you to manage your installation via time clock control,
volumetric (immediate or delayed) control or external signal start. The controller will
automatically initiate regenerations cycles based upon the programmed regeneration mode and
the programmed parameters;
•
the SFE-EV-VIRIDION controller offers the possibility to manually start regeneration simply by
pressing the regeneration button, as well as initiate a regeneration from an external signal;
•
the controller is able to receive an external signal for inhibition of regeneration cycles, that will
block any regeneration start as long as the inhibit signal is received by the controller;
•
the SFE-EV-VIRIDION controller can manage a chlorine production cell that will be activated
during the brine draw cycle of the regeneration.
The variable brining function is designed to save water and salt by optimizing the brine to be used for
resin regeneration when the controller is set up for a volumetric delayed mode (see chapter 5.3.
Installation environment, page 35 for more information on programming of this option).This function
requires that the brine for regeneration is prepared just before the regeneration cycle so that the
controller takes into account the effective water volume that has been treated compared to the total
volume capacity, and based on this value, it calculates the percentage of exhaustion of the resin bed
before starting the regeneration.
As a result the regeneration will in that case always start by the refill cycle. The quantity of water to
refill will be automatically calculated by the controller and adjusted by the percentage of exhaustion
of the resin bed so that only the required volume of brine is prepared. As an example we can assume
that if the controller registered 70% exhaustion of total resin bed capacity when starting a
regeneration, in that case it calculates the theoretical amount of water needed to prepare brine for a
complete regeneration and multiply this value by 0.7. Consequently the 30% of brine will be saved.
The percentage of brine saved for each regeneration can be displayed in the diagnostic mode of the
controller. See chapter 6.5. Statistics, page 65 for more information.
