Series 962 Electronic Demand Controls
The Series 962 Electronic 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 conditioner’s operation to meet the
application requirements. There are four basic 962
Demand models available:
Series 962 Electronic Time Clock Controls
The 962 Time Clock Controls allow regeneration/
backwash initiation several different ways. Choose the
day of the week to regenerate/backwash or set it to
regenerate/backwash on an interval basis. External
initiation is also available. This fully programmable
series of controls provide the ability to fine tune the
conditioners application to meet the operations
requirements. There are two basic 962 Time Clock
models available:
This section of the manual defines the basic operating
and programming features for each of these models.
Special Features of the Series 962 Controls
• Memory Retention - During a power outage,
critical operating information is stored in memory.
This information includes 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 and must be
reset. No other reprogramming is necessary. An
optional rechargeable battery backup will allow the
control to keep track of time and water usage for
up to eight hours during a power outage. The
control will not initiate a regeneration or backwash
while on battery backup.
• Programmable Cycles - The control is flexible in
defining the appropriate cycles of operation.
• Double Regeneration - For single tank
applications (Model 962 and 962F) the control
automatically calls for a second regeneration or
backwash the following day if the current operating
cycle exceeds the defined capacity by 150% or
more.
• Capacity and Salt Setting Lockout - The control
can be programmed to lock the values for Salt
Amount and Capacity so they cannot be altered
after installation.
• U.S. or Metric Units of Measure - To meet your
display and programming requirements, the 962
control uses grains per gallon of hardness, pounds
of salt and kilograins of capacity for U.S. units, or,
parts per million of hardness, kilograms of salt and
kilograms of capacity for metric units. The 962
control displays capacity as gallons or cubic
meters.
• Calendar Override - If the volume of water used
has not caused a regeneration, the 962 control 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 (Demand Controls Only) -
Important operating data is stored in memory and
is retrievable upon demand. The historical data
includes peak flow rate as well as average daily
water usage for each day of the week.
• Remote Regeneration - A set of terminals is
provided as a standard feature on the 962 control
that allows for a regeneration to be initiated from a
remote location. This feature can be used to
facilitate manual regeneration requirements or
assist in further automating the control system.
• Selectable Automatic Regenerations/
Backwashes - There are two automatic
regeneration/backwash methods - immediate and
delayed. Immediate regeneration is used to start
automatic regenerations/backwashes when the
softening capacity is exceeded. Delayed
regeneration is used to start automatic
regenerations/backwashes at a predetermined
time of day. A regeneration/backwash will start at
the programmed regeneration time when the
remaining capacity falls below the reserve capacity,
which may be fixed or variable.
