Control Valve Function and Cycles of Operation
This glass-filled Noryl 1(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 WS1 or WS1.25 control valve is manufactured as a
softener, the control valve can be ordered to perform downflow or upflow regeneration. When the WS1 or WS1.25
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.
* NOTE: 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 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 screwdriver, one large blade screwdriver, 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 0.5 inch above to 0.5 inch 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 (below) 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 downflow softener, two backwashes always occur. The WS1.25 control valve may not be
used as an upflow softener. When the WS1 control valve is used as an upflow softener (1 inch only), only one
backwash occurs after brining. The regenerant can refill after the rinse cycle or prefill before regeneration. When the
regenerant prefills 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: If a downflow
softener regeneration time is set for 2:00 a.m. with the prefill option selected, then the fill cycle occurs at 12:00 a.m.
and the start of the backwash cycle occurs at 2:00 a.m.

When set up as a softener, the backwash and rinse cycles automatically increase with increasing salt dosage.
Backwashes can be set to be NORMAL or LONGER. The option selected will apply to all backwashes. Tables 2
and 3 (below) show the length of the cycles when the valve is set up as a softener.

** Total Time does not include Fill Time, which is dependent upon the amount of salt needed. When in the Fill mode the system is providing treated water.
Table 4 (page 5) shows the order of the cycles when the valve is set up as a filter. When the control valve is used as
a downflow regenerating filter (i.e. both backwash and regeneration), it allows the option to specify one backwash or
two backwashes. Regenerating filters also have the option of having the regenerant refill after the rinse cycle or
prefill before regeneration. If the regenerant prefills 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: If a downflow filter regeneration time is set for 2:00 a.m. with the prefill option selected, then the fill
cycle occurs at 12:00 a.m. and the start of the 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
(page 5) show the length of the cycles when the valve is set up as a filter.
When the control valve is used as a non-regenerating filter (backwash only), it has the option to specify one
backwash or two backwashes. If two backwashes are specified, two rinses occur. Tables 5 and 6 (page 5) 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 whichever comes first, depending upon the settings selected for Day Override and
Gallon Capacity.2See Table 7 (page 6).
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.”

DIR/Time Clock Options
* Day Override and Gallon Capacity can not both be set to “oFF” at the same time.
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
0 (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 Tech 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 0 (zero).
3. “NORMAL” and “on 0” (NORMAL + on 0) means the regeneration will occur at the preset regeneration time
unless the Gallons Capacity reaches 0 (zero). If the Gallons Capacity reaches 0 (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 releasing the REGEN button will flash “Regen Today” on the display and the regeneration will occur
at the delayed regeneration time. The user can cancel the request by pressing and releasing the REGEN button.
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 the REGEN button 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 buttons
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. As new values are added, the oldest history disappears.
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.

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:
1. Softener Setup
2. Filter Setup
3. Installer Displays & Settings
4. User Displays & Settings
5. Diagnostics
6. 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 the current flow rate display under the diagnostic procedure. The current flow rate display has a
30 minute time-out feature.
To quickly exit Softener Setup, Filter Setup, Installer Display Settings, Diagnostics, or Valve History, press SET
CLOCK. Any changes made prior to the exit are incorporated.
All information in Diagnostics may be reset to 0 (zero) when the valve is moved to a new location. To reset to
0 (zero), press NEXT and buttons simultaneously to go to the Setup screen, and release. Press and 
simultaneously to reset diagnostic values to 0 (zero). The 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 9-SS (page 8) or Step 7-FS (page 10). To do a double regeneration:
1. Press the REGEN button once. “REGEN TODAY” will flash on the display.
2. Press and hold the REGEN button for 3 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.

User Display Settings
General Operation
When the system is operating, one of two
displays will be shown. Pressing the NEXT
button 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 capacity
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.
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.
When the regeneration time option is set to “NORMAL” or “NORMAL + on 0,” press and release the REGEN button
to initiate a manual regeneration at the preset delayed regeneration time, The words “REGEN TODAY” will flash on
the display to indicate that the system will regenerate at the preset delayed regeneration time. If the REGEN button
is pressed 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 the REGEN button is pressed.
To initiate a manual regeneration immediately, press and hold the REGEN button for 3 seconds. The system will
begin to regenerate immediately. The request cannot be cancelled.
NOTE: For softeners, if the brine tank does not contain salt, fill with salt and wait at least 2 hours before regenerating.
OR
REGEN TODAY
will be displayed if
a regeneration is
expected “Tonight.”
REGEN TODAY
will flash if a
regeneration is
expected “Tonight.”

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.
STEP 1-UD – Press SET CLOCK.
STEP 2-UD – Current Time (hour): Set the hour of the day using or 
buttons. AM/PM toggles after 12. Press NEXT to go to Step 3-UD.
STEP 3-UD – Current Time (minutes): Set the minutes of the day using or 
buttons. Press NEXT to exit Set Clock. Press REGEN to return to previous step.
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, this
indicates that the valve was not able to function properly. See Troubleshooting &
Error Code Guide for Tech Control Valves for help diagnosing error codes or
contact manufacturer for help.
