Familiarization
Display
As shipped from the factory, the display of the board will turn off if there has been no keyboard activity for a 1 minute period. To have a 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.
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 your
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 regen-
eration time. The time of day will need to be reset in order to return the regeneration to its preset time.
If you live in an area where power outages occur with a regular frequency, a battery backup option is available for ensuring that the
time of day is properly maintained. Contact your Culligan Dealer for more information.
