Table 1: Regeneration Cycles Softening
Tables 1 and 2 show examples when the valve is set up as a softener or lter.
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 Volume Capacity.1See Table 3.
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.

For DIR Softeners, there are two options for setting the Volume Capacity. The Volume 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 Volume Capacity to a specic number. If a specic number is set,
reserve capacity is zero, unless the value is manually set (i.e. the manufacturer intentionally sets the volume capacity number below the calculated capacity of the
system).
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 ow or the actual number of cubic meters. The counting of the cubic meters 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 cubic meters 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 “m3Capacity” set to “AUTO” and the
“Regeneration Time Option” set to “DELAY REGEN” or “BOTH”. The actual reserve capacity is compared to the capacity remaining immediately prior
to the preset regeneration time. A regeneration will occur if the actual reserve capacity is less than the 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 0.08
m3/day) in seven day intervals.
1 See Installer Display Settings, OEM Softener System Setup and OEM Filter System Setup for explanations of Day Override and Volume Capacity.
2 Days to REGEN and Volume Capacity can not both be set to “OFF” at the same time.

Page 6 CK and EQ Manual
Once the OEM Cycle Sequence has been set, the other procedures can be accessed in any order. Details on each of the procedures
are provided on the following pages.
To “lock out” access to diagnostic and valve history displays and modications to settings except hardness, day override, time
of regeneration and time of day by anyone but the manufacturer, press ▼, NEXT, ▲, and CLOCK in sequence after settings are
made. To “unlock”, so other displays can be viewed and changes can be made, press ▼, NEXT, ▲, and CLOCK in sequence.
When in operation normal user displays such as time of day, volume remaining before regeneration, present ow rate or days
remaining before regeneration are shown. When stepping through a procedure, if no buttons are pressed within ve minutes, the
display returns to a normal user display. Any changes made prior to the ve minute time out are incorporated.
To quickly exit OEM Softener Setup, OEM Filter Setup, Installer Display Settings, Diagnostics or Valve History press CLOCK.
Any changes made prior to the exit are incorporated.
When desired, all programming and information in Diagnostics may be reset to defaults when the valve is installed
in a new location. To reset, press NEXT and ▼simultaneously to go to the Softening/Filtering screen. Press ▲and ▼
simultaneously to reset programming and diagnostic values. 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 “DELAYED REGEN” or “BOTH”
in OEM Softener System Setup or OEM Filter System Setup. To do a double regeneration:
1. Press the “REGEN” button once. REGEN TODAY will ash on the display.
2. Press and hold the “REGEN” button 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.
For Valve Type 1.0T, press and hold CLOCK and ▲for about 3 seconds to initiate an exchange of the tank in Service without
cycling the regeneration valve. After tank switch, days remaining and capacity remaining status is retained for each tank until the
next regeneration.
Prior to selecting the upow regeneration cycle, verify that the correct body, main piston, regenerant piston and stack are being
used, and that the injector plug(s) are in the correct location. Refer to the Service Manual for drawings and part numbers.
Proportional Brining
If the system is set up as a prell upow 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 as a prell
upow softener. The following options can be selected:
• NORMAL FILL - System always prells with the salt level selected.
• PROPORTIONAL FILL - If proportional brining is selected, the actual salt ll 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 ll time.
Press NEXT to go to the next step. Press REGEN to return to the previous step.
Backlight Control
As an energy-saving feature, the control will automatically turn off the display illumination after 5 minutes of inactivity. Any
further keypad activity will temporarily re-illuminate the display for 5 minutes. The Energy Saver feature default is ON.
The Master Illumination button is located in the lower right hand portion of the board. The purpose of the button is to manage
the keypad backlights and the Energy Saver feature. When the keypad backlights are OFF, pressing and holding this button for
about 5 seconds will turn the lights ON, and turn the energy-saver feature OFF, which will be indicated with a display “ENERGY
SAVER OFF”. If the button is not held until the Energy Saver Off display is shown, the backlights for the display and the
keypad will both go OFF after 5 minutes of no keypad activity. (The keypad backlights will remain OFF until either the Master
Illumination or any keypad button is pressed to turn them back ON.)

STEP 1CS
OEM Cycle Sequence
OEM Cycle Sequence instructions allows the OEM to set the order of
the cycle. The OEM Softener System Setup or the OEM Filter System
Setup allow the OEM to set how long cycles will last. The OEM may
choose up to 9 cycles in any order. END must be used as the last
cycle option. The SERVICE cycle should only be used in brine prell
applications.
The following is an example of how to set a valve so that when regeneration is initiated BACKWASH occurs rst, dn BRINE
occurs second, RINSE occurs third, and FILL occurs fourth.
Step 1CS – Press NEXT and ▼simultaneously for 3 seconds and release. Then press NEXT and ▼
simultaneously for 3 seconds and release. If screen in Step 2CS does not appear in 5 seconds the lock
on the valve is activated. To unlock press ▼, NEXT, ▲, and CLOCK in sequence, then press NEXT
and ▼ simultaneously for 3 seconds and release. Then press NEXT and ▼simultaneously for 3
seconds and release.
Step 2CS – Use ▲or ▼to select 1.0 for 1” valve, 1.25 for 1.25” valve, 1.5 for 1.5” valve, 2.0 for 2”
valve, or 1.0T for twin valve.
Press NEXT to go to Step 3CS. Press REGEN to return to exit OEM Cycle Sequence.
Step 3CS – When 2.0 is selected, an additional screen will appear. It is used to select which size ow
meter is to be used with the valve, 1.5, 2.0 or 3.0.

For Clack Corporation alternator
systems using WS1, WS1.25 or WS1.5
valves there will be an option to delay
the last two cycles of regeneration
(only “Rinse” and “Fill”). This feature
splits the regeneration into two portions. The rst portion of the regeneration will start immediately and
all programmed cycles before the “Rinse” and “Fill” cycles will be performed. After all programmed
cycles before “Rinse” and “Fill” are completed the control valve will drive to the service position
(displaying “Delayed Rinse + Fill Pending”). When the volume of the on-line unit is depleted to
10% of its programmed capacity, the control valve will be triggered to nish the second portion of
the regeneration. Once “Rinse” and “Fill” are completed, the valve will re-enter Standby mode until
requested to come on-line for Service.
For Clack Corporation alternator systems using the WS2 valve, when NEXT is pressed after selecting
VALVE A or VALVE B, a display will allow the user to set the amount of pre-service rinse time for the
stand by tank just prior to returning to service.

Conguring the Control Valve for Separate Source Operation:
Select Separate Source for control operation. For separate source operation, the three wire connector
is not used. Selection requires that a connection to a Clack Motorized Alternator Valve (MAV) is made
to the two pin connector labeled MAV MTR located on the printed circuit board. The C port of the
MAV must be connected to the valve inlet and the A port connected to the separate source used during
regeneration. The B port must be connected to the feed water supply.
When set to Separate Source the MAV will be driven closed before the rst regeneration cycle, and be
driven open after the last regeneration cycle.
NOTE: If the control valve enters into an error state during regeneration mode, the MAV will either
remain in Service or be returned to Service until the error is corrected and reset.
Conguring the Control Valve for No Hard Water Bypass Operation:
Select NO HARD BYPASS for control operation. For no hard water bypass operation the three wire
connector is not used. Selection requires that a connection to MAV or a Clack No Hard Water Bypass
Valve is made to the two pin connector labeled MAV MTR located on the printed circuit board. If using
a MAV, the A port of the MAV must be plugged and the valve outlet connected to the B port. When set
to No Hard Water Bypass the MAV will be driven closed before the rst regeneration cycle that is not
FILL or SOFTENING or FILTERING, and be driven open after the last regeneration cycle that is not
FILL.
NOTE: If the control valve enters into an error state during regeneration mode, the no hard water
bypass valve will either remain in Service or be returned to Service until the error is corrected and
reset.

Note: Clack Twin Alternator Operations
• Twin alternating systems can be programmed with a day override setting combined with the normal volume-based regeneration
programming. A twin alternating system in this conguration will then regenerate based on the volume used or the day override if there is
a period of low water usage.
• Twin alternating systems can be programmed as a time clock only based regenerating system. In this conguration, the days remaining are
counted only on the unit that is in service. The unit in Stand-by Mode only notes days in diagnostics, which results in time clock only twin
regeneration initiation.
• Twin alternating systems can be programmed for a delayed regeneration time. The system will allow an immediate transfer of the MAV
to switch tanks and place a fully regenerated unit in service once a unit becomes exhausted. The exhausted unit will then be placed into
Stand-by Mode and allowed to have a delayed regeneration at the pre-set time.
Conguring the Control Valve to operate with Clack System Controller:
Select SYSTEM CONTROLLER to link the Control Valve to the Clack System Controller. For
communication between the Control Valve and the System Controller, a three-wire communication
cable is required. Selection requires that a connection to a Clack No Hard Water Bypass (V3070FF
or V3070FM) be made to the two-pin connector labeled MAV located on the printed circuit board for
WS1and WS1.25 control valves. For valve types WS1.5 and WS2, a connection from a Clack No Hard
Water Bypass (V3097/BSPT or V3098/ BSPT) to the two pin connector labeled MAV located on the
printed circuit board is required.
Press NEXT to go to Step 5CS. Press REGEN to return to previous step.

Page 10 CK and EQ Manual
STEP 5CS Step 5CS – Set Auxiliary Drive Output (MAV only) to operate in one of three modes:
• Set TIME: Allows Auxiliary MAV to switch positions at a set time in relation to the start of
regeneration for a preset duration, independently of the actual regeneration status.
• Set SEPARATE SOURCE: Allows Auxiliary MAV to switch positions before the start of
regeneration and then switch back at the end of regeneration.
• Set OFF: Deactivates this output.
Only use Clack Motorized Alternating Valves (MAV) with these selections. Clack No Hard Water
Bypass Valves (1” or 1.25” V3070FF or V3070FM) are not designed to be used with the “TIME” or
“SEPARATE SOURCE” modes.

Step 6CS – This allows the use of an outside signal to control the initiation of a regeneration.
Selection only matters if a connection is made to the two pin connector labeled DP SWITCH
located on the printed circuit board. Following is an explanation of the options:
oFF – Feature not used.
NOTE: In a twin alternating system each control must have a separate dP signal or dP
switch. One dP signal or one dP switch cannot be used for both controls. For Alternator
Systems only - the DP input is ignored on units while they are in Regeneration or
Standby.
IMMED REG – If the dP switch is closed for an accumulative time of 2 minutes a regeneration
will be signaled to the unit. In a twin alternating system the MAV will transition rst to switch
units so that the signaled unit can start regeneration. After the MAV is fully transitioned the
regeneration begins immediately. Note: For WS1 – WS1.5 control valves programmed for twin
alternating: if the dP function “IMMED REG” is set, the Delayed Rinse and Fill feature is not
available.
DELAY REG – If the dP switch is closed for an accumulative time of 2 minutes a regeneration
will occur at the scheduled delayed regeneration time. In a twin alternating system once the dP
switch is triggered the PC Board will display “REGEN TODAY” and when the delayed regen
time comes the control will switch tanks and the triggered unit will then go into regeneration.
Note: For WS1 – WS1.5 control valves programmed for twin alternating: if the dP function
“DELAY REG” is set, the Delayed Rinse and Fill feature is not available.
HOLD REG – If the dP switch is closed a regeneration will be prevented from occurring while
there is switch closure. In a twin alternating system the regeneration of a unit can be prevented
upon switch closure. If the unit depletes the capacity down to zero it will not be allowed to
switch tanks to regenerate until the switch is open. Note: For WS1 – WS1.5 control valves
programmed for twin alternating the Delayed Rinse and Fill feature can be set in conjunction
with the “HOLD REG” if desired.
