This option controls which unit format should be displayed in
the valve display.
The unit will initiate a regeneration at the next pre-set
regeneration time based on the interval of regeneration
days.
This is the most common setting. When the volume
remaining reaches zero, the system will initiate a
regeneration at the next pre-set regeneration time.
This setting is the current date. The date is used to track the
last time the system regenerated.
This setting controls the time when a regeneration cycle will
start.
This value is the interval (days) between regenerations. It is
used to determine how many days between regenerations.
This value is the total capacity between regenerations. It is
used to determine how many gallons can be used between
regenerations.
This setting controls the length of time for the unit to clean
the bed by reversing the flow of water upwards through the
bed and out to the drain.
This setting controls the length of time for the unit to draw
regeneration (brine for softeners) from the brine tank and
slowly rinse it from the top to bottom of the media tank.
This setting controls the length of time to give the tank a final
rinse from the top to the bottom in order to remove any last
traces of the regeneration from the tank.
This setting controls the length of time which the brine valve
will open to refill the brine tank with water in order to produce
the regeneration solution for the next regeneration cycle.
The water accurately measured through the valves brine line
flow control to make a precise quantity of regeneration
solution.
This setting is the current time of day.
When the volume remaining reaches zero, the system will
initiate a regeneration at the next pre-set regeneration time.
If the days between regeneration are reached before the
volume remaining reaches zero, the system will override the
meter setting and initiate a regeneration.
The unit will initiate a regeneration immediately after the
volume remaining reaches zero.
PARAMETER OPTIONS DESCRIPTION

V. Manual Regeneration
• Press and hold the key “ ” for 3 seconds to unlock screen.
• Press and hold the key “ ” for 3 seconds to initiate a manual regeneration. Screen will display:
“BACKWASH” starts flashing. When the valve reaches “BACKWASH” position, “BACKWASH” stops flashing. Dash line (the
second raw) will be shortened on the way of regeneration. Pressing any key will automatically advance the valve to the
next cycle position: BRINE, Screen will display:
Valve will be advanced to the rest of the regeneration (RINSE and REFILL) just like the above steps.
