MANUAL REGENERATION
NOTE: For softeners, if brine tank does not contain
salt, fill with salt and wait at least 2 hours before
regeneration.
If you need to initiate a manual regeneration, either
immediately, or tonight at the preprogrammed time
(typically 2 a.m.), complete the following steps.
For Immediate Regeneration:
Press and hold UP and DOWN simultaneously until
valve motor starts (typically 3 seconds).
Arrow will point to Regen if a
regeneration is expected “Tonight.”
To shut off water to the system, please position arrow handles as shown in the bypass operation diagram
below. If your valve doesn’t look like the diagram below, contact your service technician for instructions
on how to shut off water.

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 downflow regeneration water softener or filter.
The time clock control valve can be set to perform downflow regeneration or simply backwash. The time clock control valve has
two calendar options for regeneration frequency:
1. an option where the user can choose the number of days (1-99) between each regeneration; and
2. a seven-day option where the user can choose which day(s) of the week a regeneration should occur.
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. TheAC adapter power
pack is for dry location use only. If the power goes out, only the time of day needs to be reset.All other values are permanently
stored in the nonvolatile memory.
Table 1 shows the time for the backwash, regenerative, and rinse cycles for the ten available programming options. Six different
programs are available for a softener, one for a regenerative filter, and three programs for backwash only filters. When the control
valve is used as a:
1. softener, one or two backwashes occur and refill always occurs after the rinse cycle (P0 through P5);
2. regenerative filter, one backwash occurs and refill always occurs after the rinse cycle (P6); and
3. backwashing filter, one backwash occurs (P7 through P9).

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. Simultaneously press the UP + DOWN buttons to start a regeneration at the
next delayed regeneration time. If a regeneration is to occur today an arrow will point to regeneration. For immediate regeneration,
simultaneously press and hold the UP + DOWN buttons for three seconds.
When in regeneration, step through the different regeneration cycles by simultaneously pressing the UP + DOWN buttons.

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 System Setup
• Installer Displays & Settings (either 1-99 Days Between Regeneration option or 7-Day option)
• User Displays
These procedures can be accessed in any order. Details on each of the procedures are provided below and on the following pages.
When in operation, normal user displays show the time of day or days remaining before regeneration. 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.
To quickly exit Installer Displays & Settings or OEM Setup, simultaneously press SET HOUR + DOWN. Any changes made prior
to the exit are incorporated.
To reinitialize the control valve, check to make sure the valve is in the User Display. Then simultaneously press SET HOUR +
DOWN or unplug power source plug (black wire) on the circuit board, and plug back in.
STEP 1SS
➟
OEM System Setup
STEP 1SS – From normal mode, press SET HOUR + UP buttons simultaneously for 3 seconds
and release. Then press SET HOUR + UP buttons simultaneously for 3 seconds and release.
STEP 2SS – Choose the desired program by pressing the UP or DOWN buttons. Prior to
selecting a program, verify the correct valve body, main piston, regenerant piston, and stack are
being used, and that the injector or injector plug(s) are in the correct locations. See Compliance
Table in Service Instructions under Injector Cap, Screen, Injector Plug and Injector section and
Figure 6. Press SET HOUR button to go to Step 3SS.
STEP 3SS – If program P0 through P6 was selected, enter in the minutes of fill using the UP or
DOWN buttons. The allowable values vary from a low of 1 to a high of 99. If program P7, P8
or P9 was selected, dashes will appear for minutes of fill. Press SET HOUR button to go to Step
4SS. Note: For each minute of fill 0.5 gallons of water is added to the solution tank. With salt
(sodium chloride) this equates to approximately 11/2pounds of salt per minute of fill.

User Displays
General Operation
When the system is operating one of two displays will be shown. Pressing UP or DOWN button will
alternate between the displays. One of the displays is always the current time of day (to the nearest
hour). The second display is the days remaining until the next regeneration. If the days remaining
is equal to one, a regeneration will occur at the next preset regeneration time. The user can scroll
between displays as desired.
If the system has called for a regeneration that will occur at the preset time of regeneration, the arrow
will point to Regen.
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 indicate the cycle of the
regeneration process (see Table 3) that is occurring and an arrow will also point to Regen. The
system will run through the steps automatically and will reset itself to provide treated water when
the regeneration is completed.

STEP 2U
Power Loss
If the power goes out current time of day will need to be reset. If the power goes out while the system is regenerating, the cycle
picks up where it was interrupted when the power returns.
Error Message
If “E1,” “E2” or “E3” appears on the display contact the OEM for help. This indicates that the
valve did not function properly.
➟
Manual Regeneration
Sometimes there is a need to regenerate the system sooner than when the system calls for it, usually referred to as
a 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, simultaneously press UP
+ DOWN buttons together and release. The arrow will point to the word Regen if a regeneration is
expected “tonight.” To cancel the regeneration simultaneously press UP + DOWN buttons and release.
To initiate a manual regeneration immediately, simultaneously press UP + DOWN buttons together 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.
An arrow will point
to the word Regen
if a regeneration is
expected “tonight.”
