A qua-Sensor

The Aqua-Sensor
rinsed through the Cullex
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
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 regenera-
tion (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. When the Aqua-Sensor
2. When the Soft-Minder
3. When the time clock has counted past the set number of days.
4. At the preset time, when the number of days without a regeneration is equal to the days set in menu #8A.
5. At the preset time, when the 'REGEN.' button is depressed once. 'REGEN.' will light.
6. Immediately, when the 'REGEN." button is depressed twice. 'REGEN.' will light and blink.
7. 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.
