General Warnings

• The control valve, fittings and/or bypass are designed to
accommodate minor plumbing misalignments but are not
designed to support the weight of a system or the plumbing.

• HYDROCARBONS SUCH AS KEROSENE, BENZENE,
GASOLINE, ETC., MAY DAMAGE PRODUCTS THAT
CONTAIN O-RINGS OR PLASTIC COMPONENTS.
EXPOSURE TO SUCH HYDROCARBONS MAY
CAUSE THE PRODUCTS TO LEAK. DO NOT USE THE
PRODUCT(S) CONTAINED IN THIS DOCUMENT ON
WATER SUPPLIES THAT CONTAIN HYDROCARBONS
SUCH AS KEROSENE, BENZENE, GASOLINE, ETC.

• THIS WATER METER SHOULD NOT BE USED AS THE
PRIMARY MONITORING DEVICE FOR CRITICAL OR
HEALTH EFFECT APPLICATIONS.

• Do not use Vaseline, oils, other hydrocarbon lubricants or spray
silicone anywhere. A silicone lubricant may be used on black
o-rings but is not necessary.

• The nuts and caps are designed to be unscrewed or tightened
by hand or with the special plastic wrench. If necessary a
pliers can be used to unscrew the nut or cap. Do not use a
pipe wrench to tighten or loosen nuts or caps. Do not place a
screwdriver in the slots on caps and/or tap with a hammer.

• Do not use pipe dope or other sealants on threads. Use Teflon
tape on the threaded inlet, outlet and drain fittings. Teflon tape
is not necessary on the nut connection or caps because of
o-ring seals.

• After completing any valve maintenance involving the drive
assembly or the drive cap assembly and pistons unplug power
source jack from the printed circuit board (black wire) and
plug back in or press and hold NEXT and REGEN buttons
for 3 seconds. This resets the electronics and establishes the
service piston position. The display should flash all wording,
then flash the software version and then reset the valve to the
service position.

• All plumbing should be done in accordance with local plumbing
codes. The pipe size for the drain line should be a minimum
of ½”. Backwash flow rates in excess of 7 gpm (26.5 lpm) or
length in excess of 20’ (6.1m) require ¾” drain line.

• Solder joints near the drain must be done prior to connecting
the drain line flow control fitting. Leave at least 6” between the
drain line control fitting and solder joints when soldering pipes
that are connected on the drain line control fitting. Failure to do
this could cause interior damage to the drain line flow control
fitting.

• When assembling the installation fitting package (inlet and
outlet), connect the fitting to the plumbing system first and
then attach the nut, split ring and o-ring. Heat from soldering
or solvent cements may damage the nut, split ring or o-ring.
Solder joints should be cool and solvent cements should be
set before installing the nut, split ring and o-ring. Avoid getting
primer and solvent cement on any part of the o-rings, split
rings, bypass valve or control valve.

• Plug into an electrical outlet.

NOTICE

All electrical connections must be connected according to local
codes. (Be certain the outlet
is uninterrupted.)

• Install grounding strap on metal pipes.

General Warnings (continued)

• 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 water softener or filter.

• 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.

• 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 power adapter comes with a 15 foot power cord and is
designed for use with the control valve. The power adapter
is for dry location use only. The control valve remembers all
settings until the battery power is depleted if the power goes
out.

• After the battery power is depleted, the only item that needs to
be reset is the time of day; other values are permanently stored
in the nonvolatile memory. The control valve battery is not
rechargeable but is replaceable.

• No user serviceable parts are on the PC board, the motor or
the power adapter. The means of disconnection from the main
power supply is by unplugging the power adapter from the
wall.

How To Use This Manual

This installation manual is designed to guide the installer through
the process of installing and starting up water conditioning systems
featuring the ProSense controller.
This manual is a reference and will not include every system
installation situation. The person installing this equipment should
have:

• Training on the control valve.

• Knowledge of water conditioning and how to determine proper

control settings.

• Adequate plumbing skills.

Pre-Installation Considerations

A. Water Pressure

A minimum of 25 pounds of water pressure is required for
regeneration valve to operate effectively.

B. Electrical Facilities

A continuous 115 volt, 60 Hertz current supply is required. Make
certain the current supply is always hot and cannot be turned off with
another switch.

C. Existing Plumbing

Condition of existing plumbing should be free from lime and iron
buildup. Piping that is built up heavily with lime and/or iron should
be replaced. If piping is clogged with iron, a separate iron filter unit
should be installed ahead of the water softener.

D. Location Of Softener And Drain

The softener should be located close to a drain.

E. Bypass Valves

Always provide for the installation of a bypass valve.

F. Valve to Tank Installation Instructions

1. Spin the valve onto the tank, ensuring the threads are not cross­threaded.

NOTICE

The main control valve and tank adaptor have right-hand threads, or
clockwise, to install

2. Rotate the valve freely without using force until it comes to a stop
(this position is considered zero).

3. Rotate the valve clockwise from zero, between ¼ turn and ½
turn to fully tighten. No tools are needed. Hand tight is enough.
Overtightening may cause valve or tank damage.

NOTICE

If lubricant is required, a silicone compound is strongly
recommended. Dow Corning
Watts), is recommended for best possible results. Dow Corning
Release Compound is used in the manufacture of this control valve.
The use of other types of lubricants may attack the control’s plastic
or rubber components. Petroleum-based lubricants can cause
swelling in rubber parts, including O-rings and seals.

Pre-Installation Considerations
(continued)

G. Pre Installation and Loading of Media

Systems that are 13” in diameter and larger are not loaded with
media. These systems must be loaded with media before placing
into service. To load a system follow the below steps.

1. Cap the top open end of the distributor tube with tape and
plastic sheeting to keep foreign debris from entering the
distributor tube. This cap must be secure and not come off
during media loading.

2. Place the distributor tube, screen end down, into the mineral
tank and center it in the bottom. The top of the distributor
tube should be flush with the top of the tank. If 4” x 2.5” tank
bushings are used, the distributor tube should be flush with the
top of the tank bushing.

3. Make sure the plastic and tape cap is secure to the top of the
distributor tube, place a funnel on the top of the tank and load
first the gravel (if different sizes of gravel are used load the
largest gravel first, then the smaller gravel) then the resin media
into the tank. The cap must not come off of the distributor tube
during the loading of the media.

4. Remove the plastic cap from the distributor tube. DO NOT
PULL UP ON THE DISTRIBUTOR TUBE when removing the
cap. The distributor tube top must remain flush with the top of
the tank.

5. Clean any media from the threads and top of the mineral tank.

6. Lubricate the O-rings on the bottom of the control valve
(distributor pilot O-ring and top of tank O-ring). Use non­petroleum based silicone lubricant only.

7. Place the control valve on top of the tank. When doing this
step, seat the top of the distributor tube inside the centered
O-ring sealed port on the bottom of the valve first then press
the valve down until the tank threads come in contact with the
valve threads. This ensures that the distributor tube is properly
seated into the bottom of the control valve. Thread the valve
on to the tank clockwise. Be careful not to cross thread the
valve or over tighten it. A hand tight snug fit is appropriate for
the control valve torque. A wrench is not necessary. Do not use
thread sealant or PTFE tape on the valve base threads.

8. The system is now ready for installation. Follow the Installation
Section in the Installation, Operation and Maintenance Manual.

!

WARNING

Do not exceed water pressure of 120 psi
(8.2 bar). Do not exceed 110°F (43.3°C).
Do not subject unit to freezing conditions.

General Installation Instructions

1. Turn off water heater(s).

2. Turn off the main water supply to the home and open an inside
faucet (cold and hot) to relieve any pressure within the plumbing
system.

3. Place the system in the desired installation location. Make
sure that the location is level and sturdy enough to support the
weight of the system once it is in operation.

4. Place the bypass valve in the bypass position.

5. Connect the cold water supply to the inlet of the water
conditioning system. While constructing the supply line, install a
master supply valve (user supplied) in the supply line and close
it.

6. Connect the feed water line to the home to the outlet of the
system.

7. Plumb the drain line to an appropriate drain abiding by all local,
city, and state codes. Use a 3/4” drain line for backwash flow
rates of 7 gpm or for drain lines of 7 gpm and less that exceed
20’ in length. Use a 1” drain line for backwash flow rates of 10
gpm and 12 gpm.

8. Connect the brine tank to the water softener control valve brine
inlet port using the factory supplied fittings and tubing. Add
enough water to the brine tank so that water covers the top of
the air check. DO NOT ADD SALT AT THIS TIME.

9. Open the user supplied feed water valve. Check for leaks and
repair as needed.

10. Allow the inside hot and cold faucet to remain open until all air
has been purged from the plumbing system. Then close the
faucet.

11. Locate Manual Regeneration Options in this manual to see
the steps to initiate an Immediate Manual Regeneration. Once
you have read that section place the system in backwash and
unplug the system from its electrical outlet once it has cycled
into the backwash position. This will stall the unit in backwash
so all air can be purged from one of the tanks.

12. Adjust the user supplied feed water valve to 1/4 open and place
the bypass valve into the service position.

13. Air will come out of the drain line until the backwashing tank is
completely purged of air. Then water will flow to drain. Allow
water to flow to drain for 15 minutes or until the water to drain
is clear of resin color throw.

14. Plug the system back into the electrical outlet and manually
cycle it through the remaining regeneration steps until it arrives
in the service position.

15. Repeat installation steps 11, 12, 13, and 14 of the General
Installation Instructions to purge the air from the second tank.

16. Check for leaks and repair as needed.

17. Installation is now complete and the system is ready for
programming and one cycle of brine tank refill so that the
correct amount of water is in the brine tank for the first
regeneration cycle. The brine tank refill must be done after
programming the system.

Only use No Hard Water Bypass Valves or Motorized Alternating Valves (MAV) with these selections. No Hard Water Bypass Valves (1” or 1.25”
V3070FF or V3070FM) are not designed to be used with the alternator or separate source functions. The V3063 and V3063BSPT motorized
alternating valves are not designed to be used as a no hard water bypass or separate source inlet if the pressure differential is more than 60 psi.

Volume

A. Configuring the Control Valve for No Hard Water Bypass Operation:

Select nHbP 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 No Hard Water Bypass Valve is made to the two pin
connector labeled ALTERNATOR DRIVE 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 nHbP the MAV
will be driven closed before the first 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 remain in its current state until the error is corrected and
reset.

Step 6CS

This display will not appear if 1.0 was selected in Step
2CS. Allows selection of one of the following using

:

▲or ▼

• the Control Valve to have no hard water bypass;

• the Control Valve to act as an alternator; or

• the Control Valve to have a separate source during

the regeneration cycle.

Select OFF when none of these features are used.

B. Configuring the Control Valve for Separate Source Operation:

Select SEPS for control operation. For separate source operation the three wire connector is not used.
Selection requires that a connection to a Motorized Alternator Valve (MAV) is made to the two pin

connector labeled ALTERNATOR DRIVE 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 SEPS the MAV will be driven closed before the first 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

remain in its current state until the error is corrected and reset.

C. Selecting the Control Valve to act as an alternator:

519.0 and higher = Use 3-wire Interconnect Cables for all communication between units.

518.3 and lower = Use 2-wire Interconnect Cables for twin alternators with independent flow meters.

Prior to starting the programming steps, connect the interconnect cable to each control valve board’s three pin connector labeled
“INTERCONNECT”. Also connect the meter cord to either control valve to the three pin connector labeled “METER”.

NOTICE

Watts W100T Twin alternators can be set up to operate with a day over-ride
setting in conjunction with the main volume based regeneration setting. If a
system is programmed for twin alternating with a delayed regeneration, a W100T
twin alternator can perform an immediate transfer of the MAV to place a fully
regenerated tank on-line and have a delayed regeneration time for the exhausted
unit. W100T Twin alternators will only count days on the unit that is on-line which
will allow the twin alternating system to regenerate based on only a day over-ride
setting when programmed to regenerate based on days.

For Watts Twin Alternating systems using W100T, CWS150, and CWS200 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 first 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
finish the second portion of the regeneration and complete the “Rinse” and “Fill”
cycles and return to Service and be placed into Standby mode, and wait to come
on-line for service.

CWS200 Valves

For Watts Twin Alternating systems using the CWS200 valve, when NEXT is
pressed after selecting ALTA or ALTB, 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.

Step 7CS

Selecting the use of an outside signal to initiate 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.

on0 – 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
first to switch units so that the signaled unit can start
regeneration. After the MAV has fully transitioned, the
regeneration begins immediately.

NOTE: For W100T-CWS200 control valves

programmed for twin alternating: if the dP
function “on0” is set, the Delayed Rinse
and Fill feature is not available.

dELy – 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 W100T-CWS200 control valves

programmed for twin alternating: if the dP
function “dEL” is set, the Delayed Rinse
and Fill feature is not available.

HoLd – 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 W100T-CWS200 control valves

programmed for twin alternating the
Delayed Rinse and Fill feature can be set
in conjunction with the “HoLd” if desired.
