Introduction Introduction Introduction Introduction
The Model 960 control provides sophisticated,
demand-based water conditioning by incorporating a
microprocessor and a water meter to electronically
monitor the amount of water used daily. Each day, at
Time of Regeneration, the control determines if the
capacity remaining is sufficient to provide conditioned
water for the next day. If the remaining capacity is too
small, the control automatically regenerates the resin
bed.
If water usage changes, the computer automatically
compensates for the change and regenerates as
needed. Regeneration is based on actual water usage.
The control provides efficient, trouble-free,
uninterrupted soft water luxury.
The Series 255 valve combines design simplicity with
glass reinforced Noryl* plastic construction to provide
an uncommonly reliable appliance.
If maintenance becomes necessary, the Model 960
Series 255 water conditioning system offers a unique
“separation” capability for quick repairs.

Special Features

Special Features
•
Memory Retention. During a power outage,
critical operating information in the control’s
memory is stored in a special electronic device
called a NOVRAM. This information includes the
time of day, water usage amounts, daily average
water usage, all programming data and the number
of days since the last regeneration. When power is
restored, the information is returned to the
microprocessor and operation resumes as if an
outage never occurred. The time of day will be late
by the length of the power outage. Because most
power outages are less than one minute in
duration, it may be months or years before the time
display requires resetting. If an outage of one or
more hours occurs, the time of day should be reset
but no other reprogramming is necessary.
•
Design Reliability. Solid-state electronics assure
many years of trouble-free performance. The
metering system has only one moving part – a
rotating turbine that measures water usage.
•
Time and Capacity Display. During normal
conditioning operation, the correct time of day
alternates with capacity on the display. The
capacity value is the number of gallons (cubic
meters for metric units) of water that the unit can
condition before another regeneration is needed.
•
Flow Indicator. The colon between the hours and
minutes in the Time of Day display flashes to
indicate the flow of service water through the valve.
This provides an easy determination of proper
meter operation.
•
Hardness and Capacity Settings. Once the
hardness and capacity settings are entered, the
information cannot be lost due to a power outage,
so reprogramming is not necessary.
•
Guest Cycle. An extra regeneration can be
achieved at any time by pressing the REGEN
button on the front panel. It takes a few minutes for
the regeneration to start. The unit completes the
regeneration in about two hours. This feature is
beneficial when you expect to use more than the
normal amount of water; for example, guest visits
or an extra heavy laundry day.

How Your Conditioner Works
In general, your water conditioner works in the
following manner. Hard water flows into the conditioner
and through the resin bed where calcium and
magnesium hardness minerals are exchanged. The
conditioned water flows out of the resin bed into your
plumbing system. After a certain amount of hard water
has passed through the conditioner, the resin cannot
remove any more minerals. This resin state is called
exhaustion and indicates that the resin needs to be
regenerated. The regeneration process restores the
conditioner’s ability to soften water. The control
monitors the amount of water that flows through the
conditioner and automatically calculates when to
regenerate the resin bed.
