8.2. Recommendations
• Use only regeneration salts designed for water softening EN973;
• for optimal system operation, the use of clean salt free from impurities is recommended (for
example salt pellets);
• do not use ice melt salt, block, or rock salts;
• the sanitizing process (both with liquid and electrochlorination) may introduce chlorine
compounds which may reduce the lifetime of the ion exchange resins. Refer to media
manufacturer specs sheets for more information.
8.3. Manual regeneration
To initiate a manual regeneration:
A Press and hold for 5 seconds.
→ The SFE-EV-VIRIDION controller can be used to either start regeneration immediately or
delay it until the programmed time.
B Use and to scroll between immediate regeneration (AI) or
delayed regeneration (Ad) at the programmed time.
C Confirm with .
→ When Delayed manual regeneration is chosen, the current day of
the week and the service icon will blink until regeneration starts.
8.4. Cancelling a regeneration
A If a regeneration has started, the regeneration can be cancelled by pressing for 5 seconds.
→ The controller will then place the valve back in the service position.
8.5. Regeneration with remote start signal and regeneration inhibit signal
With the SFE-EV-VIRIDION controller, the regenerations can be remotely started by an external signal
(dry contact) by short-circuiting the terminal block 15 and 16 at the back of the controller. The
duration of contact closure must be at least 60 seconds. The controller allows two different methods
of launching regeneration with remote start: immediate or delayed, see “Remote regeneration start
mode”, page 62 for more information on how to program it.
In the same way, any regeneration may be inhibited by short-circuiting pins 13 and 14 of the terminal
block at the back of the controller. As long as the contact between these 2 pins is closed, no
regeneration of any type can start.
