About the water softener system.
NORMAL OPERATION, CONTROL DISPLAYS
During normal operation, the present time of
day and AM or PM and DAYS TO EMPTYshow
in the control display area.
The system will automatically recharge at the
preset recharge time as needed.
FEATURE: OPTIONAL RECHARGE CONTROLS
Sometimes, a manually started 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 recharge.
The system ran out of salt.
Use one of the following features to start a
recharge immediately, or at the next preset
recharge start time.
RECHARGE TONIGHT
Touch (do not hold) the RECHARGE button.
RECHARGE TONIGHT flashes in the control display
area. A recharge will occur at the next preset
recharge start time. If you decide to cancel this
recharge, touch the same button once more.
RECHARGE NOW
Press and hold the RECHARGE button until
RECHARGE NOW starts to flash in the control
display area. The water softening system begins
an immediate recharge and, when over in about
two hours, you will have a new supply of soft
water. Once started, you cannot cancel this
recharge.
FEATURE: MEMORY
If electrical power to the water softening system is
interrupted, the control display is blank, and the blue
indicator light is off, but the control keeps correct
time for 24 hours. When power is restored, you have
to reset the present time only if the display and blue
indicator light are 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,
recharge may occur at the wrong time of day until
you reset the control to the correct time
of day.
FEATURE/SERVICE: AUTOMATIC
ELECTRONIC DIAGNOSIS
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.
