Water Meter Mode
In water meter mode, the controller keeps track of the quantity of water that has flowed through the
resin bed. Based on the influent water hardness and the hardness capacity of the resin bed, a service
life expectancy in the quantity of softened water is calculated and programmed into the control.
When the set point is reached, regeneration is triggered. In delay regeneration mode, if the predict
mode is turned on, the average daily water usage will be compared to the remaining capacity
at the regeneration delay time to predict if another day’s water usage can occur before requiring
regeneration. If enough capacity is not present then the regeneration will occur at that time. If the
predict mode is not selected the regeneration will start at time of regeneration. In immediate mode
the regeneration starts when the capacity is exhausted. If time clock backup is set and the capacity
has not been exhausted but the days since last regen is greater than time clock backup, setting the
softener will immediately regenerate.
Aqua-Sensor
®
Mode
The Aqua-Sensor is a conductivity probe that senses when a hardness front passes through the resin
bed. It functions independently of the influent water hardness so therefore, is useful in conditions
when the influent water hardness varies throughout the year. It provides for the most efficient
mode of operation. In addition to sensing when a resin bed is exhausted, it can also be used to
determine when the brine solution is rinsed from the resin bed during the Brine Draw/Slow Rinse
cycle triggering the control to move to fast rinse. This patented feature provides water savings by
optimizing the amount of rinse water required to completely rinse out the resin bed.
Manual Regeneration
Pressing and holding the regen button for 5 seconds will initiate an immediate regeneration. The
beeper will give one beep at the start of manual regeneration (when the motor starts to turn). In delay
mode, pressing and releasing the regen button will light the regen icon for regeneration to occur at
the set delay time. Pressing and releasing the regen button again will turn off the regen icon.
Predict Mode
The Predict Mode is used with the flow meter to determine the optimum regeneration point. Before
the regeneration starts, the control will compare the remaining capacity value with the average daily
water use. If the average daily water usage is less than the reserve capacity, the controller will
wait 24 more hours before regeneration. If the reserve capacity is less than the average daily water
usage, the control will initiate regeneration. This works in delay mode only. At any time, if the total
capacity value is reached, the control will initiate an immediate regeneration.
Efficiency Mode
Water softeners historically use an optimum time range to control the Regeneration cycle steps, with
a minimum and maximum time required to perform each step dependent on the salt being used,
the hardness total and iron level. Culligan typically uses the maximum time range to insure effective
Regeneration. However, if the iron content of the water to be softened is zero, and the hardness level
is less than 20 gpg, Culligan has developed a new set of regeneration times geared to reducing salt
and water usage. These times are defined under a new operating mode coined “Efficiency Mode”.
Compared to the present time values used, these new regeneration times and salt dosages are
considerably less.
