Control Valve Function and Cycles of Operation
This glass filled 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 filter. When the WS1CS or WS1.25 control valve is manufactured as a softener, the control valve
can be ordered to perform downflow or upflow regeneration. When the WS1CS or WS1.25CS control valve is set up as a filter,
the control valve can be set to perform downflow 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
efficiency rating.
It is not recommended to change control valves from downflow to upflow brining or vice versa in the field. The valve bodies
for downflow and upflow 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 flow
of water in the necessary paths to regenerate or backwash water treatment systems. The injector regulates the flow of brine or
other regenerants. The control valve regulates the flow 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 firmly 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 flashes 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. The OEM has the option of having the regenerant refill
after the rinse cycle or have the regenerant prefill before regeneration. If the OEM chooses to have the regenerant prefill before
regeneration, the prefill 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, prefill option selected, downflow softener.
Fill occurs at 12:00 a.m., start of backwash cycle occurs at 2:00 a.m. Tables 2 and 3 show the length of the cycles when different
program codes are selected.

Table 4 shows the order of the cycles when the
valve is set up as a filter. If the control valve is set
to regenerate for a filter, the OEM has the option
of having the regenerant refill after the rinse cycle
or have the regenerant prefill before regeneration.
If the OEM chooses to have the regenerant prefill
before regeneration, the prefill 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, prefill option
selected, downflow filter. Fill occurs at 12:00 a.m.,
start of backwash cycle occurs at 2:00 a.m.
When the control valve is used as a non-
regenerating filter, the OEM has the option to
specify one backwash or two backwashes. If two
backwashes are specified, two rinses occur. Tables
5 and 6 show the length of the cycles when the
valve is set up as a filter. When used as a non-
regenerating filter, the downflow piston must be
installed, the regenerant piston removed, injector
plugs must be installed in both the DN and UP
injector locations and the refill elbow must be
replaced with a refill port plug.

The control valve with a water meter can be set for Demand Initiated Regeneration (DIR) only, Time Clock operation only or DIR and
Time Clock which ever comes first, depending upon what settings are selected for Day Override and Gallon Capacity.2See Table 7.
If a control valve does not contain a meter, the valve can only act as a time clock, and day override should be set to any number and gallon
capacity should be set to off.
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
specific number. If a specific 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 control valve 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. Pressing and release REGEN. “Regen Today” will flash 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. 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 flow 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.
3 Day 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 modified 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 field technician can access all settings. To “lock out” access to diagnostic and valve
history displays and modifications 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 five minutes the display returns to a normal user display. Any
changes made prior to the five minute time out are incorporated. The one exception is current flow rate display under the diagnostic
procedure. The current flow rate display has a 30 minute time out feature.
To quickly exit OEM Softener Setup, OEM Filter Setup, Installer Display Settings, Diagnostic 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 installed in 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 8S or Step 7F. To do a double regeneration:
1. Press REGEN once. REGEN TODAY will flash 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.

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 flowing through
the system) the word “Softening” or “Filtering” flashes 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.

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 flash 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” button 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, fill 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 flash 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 flashes on and off, the non rechargeable
battery should be replaced.
Error Message
If the word “ERROR” and a number are alternately flashing 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 flash 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 flashes on and off, the
time of day should be reset and the battery replaced.
