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.

Set Regeneration (Starting) Time

NOTE: RECHARGE TIME

and a flashing 

2:00 AM

(factory default) should show in the display. This is

a good time for regeneration to start (over in about

2 hours) in most households because water is not

in use. HARD WATER is bypassed to house

faucets during regeneration. See the 

Automatic

Hard Water Bypass During Regeneration 

section.

Press the UP or DOWN button to set the

desired regeneration start time.

NOTE: 

Each press of the buttons changes the time

by one hour. Holding the buttons in changes the

time twice each second.
Be sure to observe the AM or PM

as you

did when setting the time of day.

Press the 

SELECT

button once more.

The display shows the present time of day and

RECHARGE TONIGHT 

.
