Introduction
This 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 control valve is manufactured as a softener, the control valve can be ordered to perform downflow or upflow regeneration. When the 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 set 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.
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 replenishing treated water into a regenerant tank, when applicable.
The control valve uses no traditional fasteners (i.e., screws); instead, clips, threaded caps, 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, 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 up to ½” below the top of the 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.

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 System Setup · OEM Filter System Setup · Installer Displays & Settings · User Displays · Diagnostics
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, User Displays show the time of day or days remaining before regeneration. When stepping through a procedure, if no buttons are pressed within 5 minutes, the display returns to the User Display. Any changes made prior to the 5 minute time-out are incorporated.
To re-initialize the control valve, check to make sure the control is in User Display. Then, simultaneously press NEXT and REGEN or unplug power source plug on the circuit board, wait approximately 3 seconds, and plug back in.

Button Operation and Function

OR

UP or DOWN: Either button changes the value of the setting being viewed.

NEXT: 1. Moves to the next display. 2. While viewing Time of Day, press and hold for 3 seconds to change the time of day

REGEN: 1. Toggles a manually initiated delayed regeneration on or off.
2. Holding for more than 3 seconds forces an immediate regeneration. 3. Moves back one display while in programming mode. 4. Pressing during regeneration immediately advances the valve to the next regeneration cycle step.

AND

Re-homes valve, displays the software version, and resets a manually initiated regeneration request.

Key sequence to lock and unlock software. With software locked, User and Installer levels may still be viewed and set as desired.

The control valve with a water meter can be set for the following: · Demand Initiated Regeneration (DIR) only · Time Clock operation only · DIR and/or Time Clock (whichever occurs first), depending upon what settings are selected for Day Override and Volume Capacity

See Setting Options Table.

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 Volume Capacity should be set to OFF.

Reserve Capacity is automatically estimated based on water usage if rES is used.

If a specific Volume Capacity is set, reserve capacity is zero.

The control valves can be set to regenerate immediately or at the next regeneration time by changing the Regeneration Type Option (Step 4S). There are 3 choices for settings: 1. dELY means regeneration will occur at the preset regeneration time.
2. on 0 means regeneration will occur when the volume capacity reaches zero. 3. rES means the regeneration will occur at the preset regeneration time when the calculated reserve amount has been reached.

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. The regeneration annunciator 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. Note: This method of manually initiating regeneration is NOT allowed when the Regeneration Type is set to on 0. 2. Press and hold REGEN for approximately 3 seconds to immediately start the regeneration. The user cannot cancel this request, except by resetting the control by pressing NEXT and REGEN simultaneously for 3 seconds.

Proportional Brining: If the system is set up as a pre-fill upflow softener, the control valve can also be set to normal or proportional brining. This step will appear after Step 7S and before Step 8S if the system is set up appropriately. The following options can be selected:
· STd–System always pre-fills with the salt level selected. · ProP–If proportional brining is selected, the actual salt fill time will be calculated by dividing the actual volume of treated water used by the full volumetric capacity, then multiplying this value by the maximum salt fill time.
