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. This fully
programmable control allows you to fine tune the
conditioner’s operation to meet your customer’s
application. The Series 255 valve combines design
simplicity with reinforced Noryl* construction to provide
an uncommonly reliable appliance. The inherent
reliability of the system means a long life of efficient,
trouble-free water conditioning. If maintenance
becomes necessary, the Series 255/960 water
conditioning system offers a unique separation
capability illustrated in this manual.

Special Features
•
Memory Retention.
During a power outage,
critical operating information in the control’s
memory is stored in a special electronic device.
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. If an outage of one or more hours
occurs, the time of day should be reset but no other
reprogramming is necessary. The optional
non-rechargeable battery backup feature will allow
the control to keep track of time and any water
usage for up to two days during a power outage.
•
Fully programmable regeneration cycle times.
The control is factory programmed with typical
regeneration cycle times for easy installation. The
control allows the Backwash, Rinse, and Purge
cycle times to be set by the installer to fine tune the
conditioner’s operation.
•
Automatic double regenerations for exhausted
resin beds.
If the water usage exceeds 150% of
the system capacity between regenerations, the
control will automatically call for a second
regeneration the next day even if no water is used.
This feature is included to make sure that an
exhausted resin bed is completely recharged.
•
Selectable reserve options.
The control can be
programmed to operate with one of four different
reserve options (see Parameter P15, Table 3). The
options include starting a regeneration only at a
specific time of day or having an immediate
regeneration when the capacity is exhausted. The
control can also have a fixed reserve which is a
percentage of the total system capacity or a
variable reserve which adjusts the reserve
depending upon the water usage patterns of your
customer.
•
Separate Time of Day and Time of Regeneration
settings.
The control defaults to a 2:00 a.m.
regeneration time for easy installation, but the
installer may set the regeneration to occur at any
time of the day.
•
WQA S-101 features.
The control can be
programmed to freeze the values for Salt Amount
and Capacity so the customer can’t alter them after
installation (see Parameter P18, Table 3).
•
Selectable 12-or 24-hour clock.
(See Parameter
P13, Table 3.)
•
Selectable U.S. or metric units of measure.
Use
grains per gallon of hardness, pounds of salt, and
kilograins of capacity for U.S. units. Use milligrams
per liter of hardness, kilograms of salt and
kilograms of capacity for metric units (see
Parameter P12, Table 3).
•
Selectable calendar override.
One to 30 days are
available to automatically regenerate the
conditioner if the water usage hasn’t caused a
regeneration. The default value is zero which
disables this feature (see Parameter P14, Table 3).
•
Design reliability.
Solid-state electronics assure
many years of trouble-free performance. The
metering system has only one moving part, the
rotating turbine that measures water usage and
generates electrical pulses that are counted by the
microprocessor to determine the need to
regenerate.
•
Guest cycle.
An extra regeneration can be
achieved at any time by pressing the REGEN
button on the Model 960 front panel. It takes just a
few minutes for the regeneration to start. The
regeneration takes about two hours. This feature is
beneficial when the customer expects to use more
than the normal amount of water; for example,
guest visits or an extra heavy laundry day.
•
Manual double regeneration.
Back-to-back
regenerations can be run by pressing the REGEN
push button after the first regeneration has been
running for at least one minute. This can be used to
recharge the resin bed that has operated without
salt for an extended period of time.
Superior Design
•
Fewer parts than any control system of
comparable function and most controls of lesser
function.
•
The valve may be indexed manually with or without
power to any one of its service or regeneration
positions. The Regeneration Cycle Indicator on the
