MANUAL REGENERATION
Occasionally you may find it necessary to initiate a
manual regeneration. This is done by pressing the
REGEN button on the front of the display. When you
press the REGEN button, the control performs a full
regeneration of the water conditioner immediately.
In the event the system is allowed to run out
of salt, it will be necessary to run “Back to Back”
regenerations. This can be done easily by pressing
the REGEN button one time, waiting at least one
minute and pressing the REGEN button again.
NOTE: The second regeneration will begin
immediately after the first is completed.
“Back to Back” regenerations are necessary if full
exhaustion occurs due to low regenerate levels or
system malfunction. The system works on a highly
efficient proportionate-brining method. When the
system is not aware of the lack of proper regenerate
(salt), a larger portion of the resin bed becomes
exhausted.

NORMAL OPERATION
The control will cycle between TIME OF DAY and
CAPACITY about every 10 seconds, as indicated by
the green indicator light.
Capacity in Normal Operation mode is the gallons
of water available until the next regeneration cycle.
During a regeneration cycle, the control will cycle
between TIME OF DAY and REGEN TIME REMAINING.
REGEN TIME REMAINING is the number of minutes
until the regeneration cycle is complete.
ERROR CODES
This system continuously monitors itself and
displays an error message if it detects something
wrong. This typically happens when the valve has
not advanced through the regeneration cycle
properly.
When an error is detected, the display shows the
letters “Err” with a number from 1 to 4. The table on
page 24 describes each error, the cause of the error
and the solutions.
To clear the error from the display, press any button
on the control. If the error still exists, the control will
display the error message again after 30 seconds.
SOUNDS YOU WILL HEAR
During the regeneration cycle, the softener makes
several sounds. These sounds are normal.
• Clicking sound – This occurs as the valve assembly
advances. It is the opening and closing of the
valve ports.
• Harmonic sound – As the valve transitions
between cycles in regeneration, a high-pitched
harmonic noise may be heard for a few seconds.
• Water flow sound – In the backwash and purge
portions of the regeneration, water flow is very
high – 2–3 gpm. This is required to flush the tank
of accumulated minerals and sediments.
