(REGENERATION
MODE)
CALENDAR
CLOCK
The unit will initiate a regeneration at the next pre-set
regeneration time based on the interval of regeneration days.
METER
IMMEDIATE
The unit will initiate a regeneration immediately after the
volume remaining reaches zero.
METER
DELAYED
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.
METER
OVERRIDE
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.
4
MO-DA-YE
(MONTH-DATE-YE
AR)
This setting is the current date. The date is used to track the
last time the system regenerated.
5
TIME
This setting is the current time of day.
6
REG. TIME
(REGENERATION
TIME)
This setting controls the time when a regeneration cycle will
start.
7
REG. DAYS
(REGENERATION
DAYS)
This value is the interval (days) between regenerations. It is
used to determine how many days between regenerations
9
REG. CAP.
This value is the total capacity between regenerations. It is
used to determine how many gallons can be used between
regenerations
10
BACKWASH
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.
11
BRINE
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.
12
RINSE
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.
13
REFILL
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.
14
LOAD DEFAULT
This setting allows the current settings to be erased and
changed back to the default settings.

Water Hardness Adjustment (Optional for Softener Valve)
Users can adjust the Water Hardness Adjustment Nut to get their desired water
hardness (optional for softener valve)
Operation methods:
Rotate the Water Hardness Adjustment Nut in a clockwise direction. The bigger
rotation angle, the higher water hardness.
