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 As so ci a tion (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 com pa ra ble
products currently on the market. Control valve in stal la tion 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 re gen er a tion. If the OEM chooses to have the regenerant pre ll before regeneration, the
pre ll starts two hours before the re gen er a tion 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.

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 show the length of the
cycles when the valve is set up as a softener.

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
re gen er at ing 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.
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.

These are reference numbers that approximate the amount of salt needed. The actual capacity in grains per pound of salt is
used in cal cu la tions.

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.

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 rst, depending upon what settings are selected for Day Override and Gallon
Capacity.5 See 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.
