Control Valve Function and Cycles of Operation
This glass lled Noryl1(or equivalent) fully automatic control valve is designed as the primary control center to direct and
regulate all cycles of a water softener or lter. When the WS1 or the WS1.25 control valve is manufactured as a softener, the
control valve can be ordered to perform downow or upow regeneration. When the WS1 or WS1.25 control valve is set up
as a lter, the control valve can be set to perform downow regeneration or simply backwash. The control valve can be set
to regenerate on demand (consumption of a predetermined amount of water) and/or as a time clock (passage of a particular
number of days). The control valve can be set so that a softener can meet the Water Quality Association (WQA) Standard
S100 or NSF/ANSI Standard 44 efciency rating.
It is not recommended to change control valves from downow to upow brining or vice versa in the eld. The valve bodies for
downow and upow are unique to the regeneration type and and should not be interchanged. A mismatch of valve body and
regeneration piston will result in hard water bypass during service.
The control valve is compatible with a variety of regenerants and resin cleaners. The control valve is capable of routing the
ow of water in the necessary paths to regenerate or backwash water treatment systems. The injector regulates the ow of
brine or other regenerants. The control valve regulates the ow rates for backwashing, rinsing, and the replenishing of treated
water into a regenerant tank, when applicable.
The control valve uses no traditional fasteners (e.g. screws); instead clips, threaded caps and nuts and snap type latches are
used. Caps and nuts only need to be rmly hand tightened because radial seals are used. Tools required to service the valve
include one small blade screw driver, one large blade screw driver, pliers and a pair of hands. A plastic wrench is available
which eliminates the need for screwdrivers and pliers. Disassembly for servicing takes much less time than comparable
products currently on the market. Control valve installation is made easy because the distributor tube can be cut ½”above
to ½”below the top of tank thread. The distributor tube is held in place by an o-ring seal and the control valve also has a
bayonet lock feature for upper distributor baskets.
The AC adapter power pack comes with a 15 foot power cord and is designed for use with the control valve. The AC adapter
power pack is for dry location use only. The control valve remembers all settings for up to 8 hours if the power goes out and
the battery is not depleted. After 8 hours, the only item that needs to be reset is the time of day; other values are permanently
stored in the nonvolatile memory. If a power loss lasts less than 8 hours and the time ashes on and off, the time of day
should be reset and the non rechargeable battery should be replaced.
Table 1 shows the order of the cycles when the valve is set up as a softener. When the WS1 or WS1.25 control valve is used
as a downow softener, two backwashes always occur. When the WS1 or WS1.25 control valve is used as an upow softener,
only one backwash occurs after brining. The OEM has the option of having the regenerant rell after the rinse cycle or
have the regenerant prell before regeneration. If the OEM chooses to have the regenerant prell before regeneration, the
prell starts two hours before the regeneration time set. During the 2-hour period in which the brine is being made, treated
(softened) water is still available. For example: regeneration time = 2:00 am, prell option selected, downow softener. Fill
occurs at 12:00 a.m., start of backwash cycle occurs at 2:00 a.m.

Table 4 shows the order of the cycles when the valve is set up as a lter. When the control valve is used as a downow
regenerating lter, the OEM has the option to specify one backwash or two backwashes. If the control valve is set to
regenerate for a lter, the OEM has the option of having the regenerant rell after the rinse cycle or have the regenerant prell
before regeneration. If the OEM chooses to have the regenerant prell before regeneration, the prell starts two hours before
the regeneration time set. During the 2-hour period in which the regenerant is being made, treated water is still available. For
example: regeneration time = 2:00 am, prell option selected, downow lter. Fill occurs at 12:00 a.m., start of backwash
cycle occurs at 2:00 a.m. There is only one rinse. Backwashes can be set to normal or longer. The option selected will apply to
all backwashes. Tables 5 and 6 show the length of the cycles when the valve is set up as a lter.
2These are reference numbers that approximate the amount of salt needed. The actual capacity in grains per pound of salt is
used in calculations.
3 Total time does not include ll time, which is dependent upon the amount of salt needed. When in the ll mode the system
is providing treated water.
When the control valve is used as a non-regenerating lter, the OEM has the option to specify one backwash or two
backwashes. If two backwashes are specied, two rinses occur. Tables 5 and 6 show the length of the cycles when the valve
is set up as a lter. When used as a non-regenerating lter, the downow piston must be installed, the regenerant piston
removed, injector plugs must be installed in both the DN and UP injector locations and the rell elbow must be replaced with
a rell port plug.

For DIR Softeners, there are two options for setting the Gallons Capacity. The Gallons Capacity is automatically calculated if
set to AUTO. Reserve Capacity is automatically estimated based on water usage if AUTO is used. The other option is to set the
Gallons Capacity to a specic number. If a specic number is set, reserve capacity is zero, unless the value is manually set (i.e. the
manufacturer intentionally sets the gallon capacity number below the calculated capacity of the system).
The WS1 & WS1.25 control valves can also be set to regenerate immediately or at the next regeneration time by changing the
Regeneration Time Option. There are three choices for settings:
1. “NORMAL” means regeneration will occur at the preset regeneration time.
2. “on 0” means regeneration will occur when the gallons capacity reaches zero.
3. “NORMAL + on 0” means the regeneration will occur at the preset regeneration time unless the gallons capacity reaches zero.
If the gallons capacity reaches zero the regeneration will begin 10 minutes after no water usage.
The user can initiate manual regeneration. The user has the option to request the manual regeneration at the delayed regeneration
time or to have the regeneration occur immediately:
1. Press and release REGEN. “Regen Today” will ash on the display and the regeneration will occur at the delayed regeneration
time. The user can cancel the request by pressing and releasing REGEN. This method of manually initiating regeneration is not
allowed when the system is set to “on 0”, i.e. to immediately regenerate when the gallon capacity reaches zero.
2. Pressing and holding REGEN for approximately 3 seconds will immediately start the regeneration. The user cannot cancel this
request, except by resetting the control by pressing NEXT and REGEN simultaneously for 3 seconds.
A unique feature of this control valve is the ability to display actual water usage for the last 63 days. The values are initially stored as
“----”. This means the value is unknown. As days pass values are stored as “0” for no ow or the actual number of gallons. The
counting of the gallons starts at the regeneration time. If no regeneration time can be set (i.e. when the valve is set for immediate
regeneration) the counting of gallons starts at 12 a.m. Day 1 is yesterday, day 2 the day before yesterday, etc.
Another unique feature is that the valve automatically calculates a reserve capacity when set up as a softener with “Gallons
Capacity” set to “AUTO” and the “Regeneration Time Option” set to “Normal” or “Normal + on 0”. The actual reserve capacity
is compared to the gallons capacity remaining immediately prior to the preset regeneration time. A regeneration will occur if the
actual reserve capacity is less than the gallons capacity remaining. The actual reserve capacity is calculated by using the estimated
reserve capacity and adjusting it up or down for actual usage.
The estimated reserve capacity for a given day of the week is the maximum value stored for the last three non-trivial water usages
(i.e. more than 20 gallons/day) in seven day intervals.
6Day Override and Gallon Capacity cannot be set to “oFF” at the same time.

OEM General Instructions
The control valve offers multiple procedures that allow the valve to be modied to suit the needs of the installation. These
procedures are:
OEM Softener Setup
OEM Filter Setup
Installer Displays & Settings
User Displays & Settings
Diagnostics
Valve History
These procedures can be accessed in any order. Details on each of the procedures are provided on the following pages.
At the discretion of the manufacturer, the eld technician can access all settings. To “lock out” access to diagnostic and valve
history displays and modications to settings except hardness, day override, time of regeneration and time of day by anyone
but the manufacturer, press ▼, NEXT, ▲, and SET CLOCK in sequence after settings are made. To “unlock”, so other
displays can be viewed and changes can be made, press ▼, NEXT, ▲, and SET CLOCK in sequence.
When in operation normal user displays such as time of day, gallons remaining or days remaining before regeneration are
shown. When stepping through a procedure, if no buttons are pressed within ve minutes the display returns to a normal user
display. Any changes made prior to the ve minute time out are incorporated.
To quickly exit OEM Softener Setup, OEM Filter Setup, Installer Display Settings, Diagnostics or Valve History press SET
CLOCK. Any changes made prior to the exit are incorporated.
When desired all information in Diagnostics may be reset to zero when the valve is moved to a new location. To reset to zero,
press NEXT and ▼simultaneously to go to the Service/OEM 1 screen, and release. Press ▲and ▼simultaneously to reset
diagnostic values to zero. Screen will return to User Display.
Sometimes it is desirable to have the valve initiate and complete two regenerations within 24 hours and then return to
the preset regeneration procedure. It is possible to do a double regeneration if the control valve is set to “NORMAL” or
“NORMAL + on 0” in Step 9S or Step 7F. To do a double regeneration:
1. Press REGEN once. REGEN TODAY will ash on the display.
2. Press and hold REGEN for three seconds until the valve regeneration initiates.
Once the valve has completed the immediate regeneration, the valve will regenerate one more time at the preset regeneration
time.

General Operation
When the system is operating one of two displays will
be shown. Pressing NEXT will alternate between the
displays. One of the displays is always the current time
of day. The second display is one of the following: days
remaining or gallons remaining. Days remaining is the
number of days left before the system goes through a
regeneration cycle. Capacity remaining is the number
of gallons that will be treated before the system goes
through a regeneration cycle. The user can scroll
between the displays as desired.
If the system has called for a regeneration that will
occur at the preset time of regeneration, the words
REGEN TODAY will appear on the display.
When water is being treated (i.e. water is owing
through the system) the word “Softening” or
“Filtering” ashes on the display if a water meter is
installed.

Regeneration Mode
Typically a system is set to regenerate at a time of low water usage. An example of a time
with low water usage is when a household is asleep. If there is a demand for water when
the system is regenerating, untreated water will be used.
When the system begins to regenerate, the display will change to include information about the step of the regeneration
process and the time remaining for that step to be completed. The system runs through the steps automatically and will reset
itself to provide treated water when the regeneration has been completed.
Manual Regeneration
Sometimes there is a need to regenerate the system sooner
than when the system calls for it, usually referred to as manual
regeneration. There may be a period of heavy water usage
because of guests or a heavy laundry day.
To initiate a manual regeneration at the preset delayed
regeneration time, when the regeneration time option is set to “NORMAL” or “NORMAL
+ on 0”, press and release REGEN. The words “REGEN TODAY” will ash on the
display to indicate that the system will regenerate at the preset delayed regeneration time. If
you pressed REGEN in error, pressing the button again will cancel the request. Note: If the regeneration time option is set to
“on 0” there is no set delayed regeneration time so “REGEN TODAY” will not activate if REGEN is pressed.
To initiate a manual regeneration immediately, press and hold REGEN for three seconds. The system will begin to regenerate
immediately. The request cannot be cancelled.
Note: For softeners, if brine tank does not contain salt, ll with salt and wait at least two hours before regenerating.
Power Loss
If the power goes out, the system will keep time for up to 8 hours or until the battery is depleted. If a power outage of more
than 8 hours occurs, the time of day will ash on and off which indicates the time of day should be reset. The system will
remember the rest. If a power outage lasts less than 8 hours and the time of day ashes on and off, the non rechargeable
battery should be replaced.
Error Message
If the word “ERROR” and a number are alternately ashing on the display
contact the OEM for help. This indicates that the valve was not able to function
properly.
Set Time of Day
The user can also set the time of day. Time of day should only need to be set after power
outages lasting more than 8 hours, if the battery has been depleted and a power outage
occurs, or when daylight saving time begins or ends. If a power outage lasting more than
8 hours occurs, the time of day will ash on and off which indicates the time of day
should be reset. If a power outage lasts less than 8 hours and the time of day ashes on
and off, the time of day should be reset and the battery replaced.
