1. CONTROL VALVE FUNCTION AND CYCLES OF OPERATION
This glass fi lled Noryl
1
(or equivalent) fully automatic control valve is designed as the primary control
center to direct and regulate all cycles of a downfl ow regeneration water softener or filter.
The time clock control valve can be set to perform downfl ow 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 com pa ra ble 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 power supply comes with a 15 foot power cord and is designed for use with the control valve. The
power supply is for dry location use only. The control valve maintains timekeeping 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; valve status and programming are permanently stored in the nonvolatile memory. If a power
loss lasts less than 8 hours and the time flashes on and off, the time of day should be reset and the non
rechargeable battery should be replaced.
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:
• Softener - one or two backwashes occur and refill always occurs after the rinse cycle (P0 through P5)
• Regenerative Filter - one backwash occurs and refill always occurs after the rinse cycle (P6)
• 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 ▲ and ▼ to start a regeneration at the next delayed regeneration time. If a regeneration is to
occur “today” an arrow will point to REGEN. For immediate regeneration, simultaneously press and
hold ▲ and ▼ for three seconds.
When in regeneration, step through the different regeneration cycles by pressing ▲ or ▼.
