Feature/Service: Automatic Electronic Diagnostics
The control computer has a self-diagnostic function
for the electrical system (except input power and
water meter). The computer monitors the electronic
components and circuits for correct operation. If a
malfunction occurs, an error code appears in the
control display.
The chart on
Error Codes
shows the error
codes that could appear and possible reasons for
each code. While an error code is displayed, all
control buttons are inoperable except for the
SELECT
button.
SELECT
remains operational so the service
person can make the
Manually Initiated Electronic
Diagnostics
to further isolate the defect and check
the water meter.
Normal Operation, Control Displays
During normal operation, the present time of day and AM or PM show in the control display area. When
the demand computer determines a regeneration is needed,
RECHARGE TONIGHT
begins to flash in the display
along with the present time.
RECHARGE TONIGHT
flashes until the next regeneration start time, then
changes to
RECHARGE NOW,
which flashes until the regeneration is over.
Feature: Program Memory
If electrical power to the water softening system is
interrupted, the control display is blank, but the
control keeps correct time for about six hours. When
power is restored, you have to reset the present time
only if the display is flashing. All other settings are
maintained and never require resetting unless a
change is desired.
If the time is flashing after a long power outage, the
water softening system continues to work as it should
to provide you with soft water. However, regenerations
may occur at the wrong time of day until you reset the
control to the correct time of day.
Feature: Optional Recharge Controls
Sometimes, a manually started regeneration
(recharge) may be desired or needed.
Two examples:
■You have used more water than usual (house
guests, extra washing, etc.) and you may run out
of soft water before the next regeneration.
■You did not refill the storage tank with salt.
Use one of the following features to start a
regeneration immediately, or at the next preset
regeneration start time.
RECHARGE TONIGHT
Touch (do not hold) the
TOUCH or HOLD
button.
RECHARGE TONIGHT
flashes in the control display
area. A regeneration will occur at the next preset
regeneration start time. If you decide to cancel this
regeneration, touch the same button once more.
RECHARGE NOW
Press and
hold
the
TOUCH or HOLD
button until
RECHARGE NOW
starts to flash in the control display
area. The water softening system begins an immediate
regeneration and, when over in about two hours, you
will have a new supply of soft water. Once started, you
cannot cancel this regeneration.
