Series 962 Electronic Stager Controls

The Series 962 Electronic Stager Controls provide
sophisticated, demand-based water conditioning by
combining a microprocessor with a flow meter to
electronically monitor the amount of water used. This
fully programmable series of controls provide the ability
to fine tune the operation to meet the application
requirements. There are several 962 Stager models
available.
Single Unit Controls
Basic Softeners & Filters
Complex Softeners & Filters
Multiple Unit Controls
Twin Alternating Softeners &
Filters
Sequential Filters
(Backwash Only)
2 Unit Sequential Filters
3 or 4 Unit Sequential Filters

Control

Memory Retention

During a power outage, critical operating information is
stored in nonvolatile memory. This information includes
the time of day, 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. The time of day should be reset
after an extended power outage. No other
reprogramming is necessary. An optional backup
battery will allow the control to keep track of time and
water usage for up to 8 hours during a power outage.
The control will not initiate a regeneration while on
battery backup.

Programmable Cycles

The control is flexible in defining the appropriate cycles
of operation.

Double Regeneration

For single tank applications, the control automatically
calls for a second regeneration the following day if the
current operation cycle exceeds the programmed
capacity by 150% or more.

Capacity Setting Lockout

The control can be programmed to lock the capacity so
it cannot be altered after installation.
Model No.

Selectable Reserve Options

E948
To meet the application requirements, the control allows
E951
selection of one of two reserve types:
Fixed Reserve - The reserve is fixed at a
programmable percentage (30% factory preset) of
Model No.
the total capacity.
E958-TA
Variable Reserve - The controller monitors the
E958-TB
daily water usage and at the programmed time of
regeneration, calculates the average water used
E948
for each day of the week. The reserve capacity is
E951
set to 120% of the average water usage for the
E958 next day.

U.S. or Metric Units of Measure

To meet your display and programming requirements,
the 962 Stager uses grains per gallon of hardness and
kilograins of capacity for U.S. units; or parts per million
of hardness and kilograms of capacity as gallons or
cubic meters.

Calendar Override

If the volume of water used has not caused a
regeneration, the 962 Stager can be set to regenerate
every one to thirty days.

Manual Regeneration

A separate REGEN button is provided for manual
regenerations. A double manual regeneration feature is
included that allows back-to-back regenerations.

Operating Histories

Important operating data is stored in memory and is
retrievable upon demand.
The historical data includes peak flow data as well as
average daily water usage for each day of the week.
