Circuit Board
The AccuSoft™ microprocessor circuit board controls every function of the Culligan Mark 100 water softener. This board
has several unique features which allow it to perform a variety of functions. Familiarization of the board is essential for
a thorough understanding of the softener.
TABLE 2
The AccuSoft™ circuit board has a set of default
settings that the microprocessor will reset to whenever any dip switches are flipped, or if a meter or
Aqua-Sensor cable is attached or removed while the
power is on the the control. Table 2 is a list of the
default microprocessor settings.
It is reccomended to always disconnect the power
from the circuit board prior to replacing an AquaSensor probe or Meter cable so that the programmed
settings are not lost.

A qua-Sensor Operation
The Aqua-Sensor models contain a feature which can automatically detect when the brine solution has been
rinsed through the Cullex media. This feature will advance the control to the next position when it senses that
the brine has been rinsed out prior to the time set in the brine rinse option. The Brine/Rinse time can be manually
raised or lowered in the microprocessor.
Tables 3A and 4A show the total capacity of the Aqua-Sensor unit at various salt dosages, along with the
average capacity used prior to a signal calling for a regeneration.
To view the length of the last Brine/Rinse cycle, press the STATUS button until the display is blank. Press the
down arrow until the number 15 is illuminated. See the Service Check section for more information.
S oft-Minder Operation
The microprocessor automatically calculates the gallons of water which can be treated based on the salt dosage,
the water hardness, and the tank size. Numeric enunciator 8 will display the GALLONS TO SIGNAL for regeneration (the portion of the capacity which is held in reserve is not displayed).
NOTICE: Changes to the salt dosage, or water hardness will not immediately update the GALLONS TO
SIGNAL setting. The control will recalculate the setting upon completion of a regeneration cycle.
As an option GALLONS TO SIGNAL for regeneration can be set to directly override the calculation through
numeric enunciator 8. The gallon value can be raised or lowered to meet the needs of your specific application.
The control must be cycled through a complete regeneration before the gallon override setting is stored by the
microprocessor.
NOTICE: Changing the capacity will affect the reserve capacity. An INCREASE in the gallons capacity will
DECREASE the reserve capacity. A DECREASE in the gallons capacity will INCREASE the reserve capacity.
Refer to Tables 3B and 4B to determine the units total capacity based on salt dosage and the hardness level.
The gallons remaining can be viewed by pressing the STATUS button until the display is blank. Press the down
arrow until the number 15 is illuminated. The value in the display must be multiplied by 10 to determine the
actual gallons remaining before the unit calls for a regeneration. The unit will initiate an immediate regeneration if
dip switch 6 in the ON position. See the Service Check section for more information.
Regeneration
There are several conditions that will cause the control to trip a regeneration. The 'REGEN' enunciator will light
when the control has signaled for a regeneration. The 'REGEN' enunciator will flash while the control is in
regeneration.
The following are conditions that will call for regeneration:
1.
2.
3.
4.
5.
6.
7.
When the Aqua-Sensor® probe senses the hardness in the Cullex® media.
When the Soft-Minder® meter has recorded the passage of a predetermined number of gallons.
When the time clock has counted past the set number of days.
At the preset time, when the number of days without a regeneration is equal to the days set in menu #8A.
At the preset time, when the 'REGEN.’ button is depressed once. 'REGEN.' will light.
Immediately, when the ‘REGEN.” button is depressed twice. 'REGEN.' will light and blink.
Immediately, if power to the unit has been off for more than 3 hours.
If dip switch 6 is in the ON position the unit will begin a regeneration immediately for instances 1 and 2. With dip
switch 6 in the OFF position, the regeneration will not begin until the preset regeneration time.

Display Blanking
As shipped from the factory, the display of the board will turn off if there has been no keypad activity for a 1 minute
period. To have the display constantly lit, press the STATUS button until the number 10 icon is lit. Next, press the
UP arrow. A “d” for disable will appear in the display. To have the display blank again , press the UP arrow. An “E”
will appear in the display .
Display Lockout
The Culligan® Mark 100 control is equipped with a new feature which will allow you to protect the programmed
settings from tampering by unauthorized individuals. When the lockout feature is activated, the only parameter
which can be adjusted is the Time-of-Day.
To activate the lockout feature, press the STATUS button until the number 9 icon is illuminated. A “U” for unlock will
be displayed. Press the UP and DOWN arrows simultaneously. A “L” for lock will appear along with an icon of a lock.
All program parameters, except time of day, are now frozen at their current settings. To disable this feature, press the
UP and DOWN arrows simultaneously.
Power Loss
The AccuSoft® circuit board is equipped with a Hi-Cap Capacitor and EEPROM memory chip. The capacitor is
capable of maintaining the time, for at least one day, in the event of a power outage. The EEPROM ensures that the
individual programming parameters of the softener are not lost.
If the power outage lasts long enough to drain the Hi-Cap Capacitor, the control will flash "12:00 PM" when
power is returned to the control. The unit will continue to keep time from the moment power is restored, and will
initiate a full regeneration at the preset regeneration time. The time of day will need to be reset in order to return
the regeneration to its preset time.
Failure Mode
The Culligan Mark 100 control is equipped to detect a motor or piston which is locked in a frozen position. The
AccuSoft™ circuit board will apply power to the motor for 30 seconds. If there is no change in the motor homing or
position switch, the control will power down for 90 seconds. The circuit board will repeat this procedure two more
times in an attempt to remove the obstruction. If no movement has been detected, the control will permanently
power down and a phone icon will appear in the display. The phone indicates that a service call is required to fix the
control. To return to the service mode, turn off the power to the unit for 1 full minute and remove the obstruction to
the motor or piston.

Board Diagnostics
Board Diagnostic
To enter the board test mode, flip all of the dip switches to the ON position. All the segments of the board will light until
either a key is depressed, an option is changed or a CAM micro switch changes position. Pressing one of the keys,
closing a micro switch or turning OFF a dip switch will cause a different segment to light as outlined in Table 5.
A balanced signal should be applied to the Aqua-Sensor® pin connector. This can be done with a clean Aqua-Sensor
probe and a fully regenerated bed or with the Aqua-Sensor Tester, PN 01-0079-99.
An unbalanced signal will cause the drive motor to run continuously. A balanced signal will cause the motor to stop.
This test can be used to check the integrity of the Aqua-Sensor probe. If the probe is connected to the board and
the drive motor runs continuously, the probe should be cleaned and checked.

Wiring Diagram
WIRING DIAGRAM 23
“A” Dimension Charts/Refill Rates
The “A” dimension is the distance from the top of the filter screen of the brine valve chamber to the bottom edge of
the lower float when the stem is in the fully raised position.
Refer to Table 8 for the correct “A” dimension (secondary shutoff) for the salt dosages on the water softener
models. Adjust the “A” dimension as follows (Figure 8).
•
•
•
•
Lift the brine valve from the brine chamber.
Find the correct “A” dimension from Table 8.
Set the distance from the top of the filter screen to the base of the float accordingly. The slight difference in
height when the float is pulled up or down is negligible.
Place the float assembly back in the chamber.
Refill Flow Control
As shipped from the factory, a 0.45 gpm refill flow control is used to control the refill flow rate. This is the standard
refill rate as referenced in Table 8. An optional 0.80 gpm flow control is available (PN 00-4016-23). It is recommended
that the 0.80 gpm flow control is used when salt dosages are greater than 15 lb. Replace the flow control as follows:
•
•
•
•
Lift the brine valve from the brine chamber.
Grasp the knurled top of the brine cap and unscrew it.
Remove the 0.45 gpm flow control and replace with the 0.80 gpm control.
Screw the top in and place the float back into the chamber.
NOTICE: When changing to the 0.80 gpm flow control, remove the 0.45 gpm label from the top of the brine cap.
This will help to eliminate confusion at a future date.
NOTICE: When using the 0.80 gpm flow control, shift the #5 dip switch to the ON position. This enables the fast
refill mode for the softener.

SALT STORAGE ELEVATION
For each foot the salt storage tank is lowered below the floor on which the softener stands, it is necessary to deduct 8 feet of drain line from the
allowable length shown on the chart. For each foot the salt storage tank is elevated above the floor on which the softener stands, the height of drain
discharge can be raised 2 inches, or the total length of the drain line can be increased 4 feet. In either case, deduction must also be made for extra
feet of brine line length in excess of the standard 4 feet. For this deduction, use column entitled, “EXTRA BRINE LINE”.
