• Selectable Reserve Options (Demand Controls
Only) - To meet the conditioned water
requirements of the application, the 962 control
allows selection of one of two reserve types:
– Fixed Reserve - The reserve is fixed at a
progammable percentage (30% factory preset)
of the total softening capacity.
– Variable Reserve - The controller monitors the
daily water usage and at the programmed time
of regeneration, calculates the average water
used for each day of the week. The reserve
capacity is set to 120% of the average water
usage for the next day.
• Delayed Regeneration on Twin-alternating
Systems - The twin-alternating system does not
use a reserve capacity. The service tank switches
when the softening capacity is exhausted.
Regeneration of the exhausted tank will occur at
the specified time of day when using the delayed
regeneration feature.
• Immediate Regeneration on Twin and Triple
Parallel Systems - The twin and triple parallel
systems use a reserve capacity of “0” along with
immediate regeneration. Regeneration of an
exhausted tank in the system will occur
immediately after reaching its maximum capacity,
IF, there are no other tanks within the system
already regenerating.
Normal Display Modes
In the normal operating mode the Series 962 control
will alternate between Capacity Remaining (gallons or
m
3
) and Flow Rate (gallons per minute or m/hr). In the
event of power loss, the display will alternate between
Time of Day and Capacity Remaining once power
has been restored. The normal operating display mode
of the twin alternating system scrolls through three
displays. They are: Capacity Remaining of tank 1 in
gallons, Capacity Remaining of tank 2 in gallons, and
Flow Rate. If a power outage has occurred, the flow
rate display will change to Time of Day. In both cases
the control will remain in Power Loss display mode
until the Time of Day is reset or until any button is
pressed. (Electronic Time Clock displays Time of Day
only).
Programming the Series 962 Controls
This section contains common aspects of
programming the 962, 962F, and 962M controls and
retrieving historical operating data. The 962S control is
a secondary unit that always works in conjunction with
the 962M main control for twin alternating tank
applications. The operating values for the 962S are the
same as the operating values in the 962M control. An
adhesive installation label is provided with each 962,
962F, and 962M control. It is recommended that this be
filled out with programming parameters on start-up and
placed on the inside of the cam cover.
Factory Default Values - The control is shipped from
the factory with a default value for Salt Amount of 10 lb.
(4 kg for metric units). Capacity, Hardness, Refill and
Brine Draw values are set to 0 and must be changed
to appropriate values before the control will
operate. “Err 4” will be displayed until a valid
number is entered for each of these items. Program
variable P12 is preset at the factory to define the U.S.
units of measure for North American application or
metric units of measure for application outside North
America.
Program Levels - The Series 962 controls have been
designed to facilitate different levels of programming
requirements. Level I includes program variables that
are frequently referenced by users, operators,
installers, and service personnel, and is accessible
without the requirement of codes. Level II includes
variables that are most typically used at the time of
installation and initial setup and is accessible with
special access codes. Level III locations are used
primarily for accessing operating history information.
Level III parameters also require access codes.
Programming levels are further defined in Section 6
(page 34).
Table I on page 34 lists the Level I program values for
the 962, 962F, 962TC, 962FTC and 962M controls.
Tables IIA through IIE, on pages 35-41, list the Level II
program values for all 962 series controls.
Program Values and Locations - The P values that
are programmed into the Series 962 controls are listed
in the Level I and Level II tables.
Locating a Program Value - To locate and display a P
value in Level I press the UP [
↑ ] or DOWN [↓] arrow
button until the desired value is displayed.
To locate and display a P value in Level II,
simultaneously press the UP [
↑ ] and DOWN [↓] arrow
buttons for 3 seconds to gain access. Press the UP [
↑ ]
or DOWN [
↓] arrow buttons until the desired location is
displayed. Press LEFT [
←] to display a value in P
locations.
To locate and display an L value in Level III,
simultaneously press the LEFT [
←] and UP [↑ ] arrow
buttons for 3 seconds to gain access and the press the
UP [
↑ ] or DOWN [↓] arrows buttons until the desired
location is displayed. Press LEFT [
←] to display value in
the L location.
