The second raw shows regeneration time.

D-07

02:00 AM

●Meter Immediate, Meter Delayed, Meter Override:

The first raw is the volume remaining of one regeneration cycle in meter. “G”

refers to Gallon

The second raw is total usage.

PARAMETER

OPTIONS

DESCRIPTION

REGIONAL

METRIC

This option controls which unit format should be displayed in

the valve display.

(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.

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.

TIME

This setting is the current time of day.

REG. TIME

(REGENERATION

TIME)

This setting controls the time when a regeneration cycle will

start.

REG. DAYS

(REGENERATION

DAYS)

This value is the interval (days) between regenerations. It is

used to determine how many days between regenerations

REG. CAP.

This value is the total capacity between regenerations. It is

used to determine how many gallons can be used between

regenerations

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.

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.

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.

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.

LOAD DEFAULT

This setting allows the current settings to be erased and

changed back to the default settings.

Valve will be advanced to the rest of the regeneration (RINSE and REFILL) just like the

above steps.

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.
