SECTION 2
.ow YOUR WATER SOFTENER WORKS
2B. SOFT WATER SERVICE AND REGENERATION
AUTOMATIC BYPASS
During the brining, brine rinse and backwash cycles
of regeneration, hard water goes through the
softener valve and to the house pipes. If a faucet is
opened, hard water is there for your needs.
However, you should not use HOTwater, if possible,
because the water heater will refill with hard water.
The softener regenerates from 2:00 AM to about 4:00
AM, (you can set anytime), a time when not much
water is used.
If you get up early in the morning and you can hear
the softener regenerating, change the time setting.
Set the recharge time to 12:00 AM or 1:00 AM (page
7). Then regeneration will start and end that much
earlier and your water heater will not refill with hard
water if a hot faucet is opened.
ELECTRONICS
Two main parts of the softener's electronics are [] a
WATER METER, and [] a COMPUTER.
[] WATER METER -- The water meter is in the
softener valve outlet. As water flows through the
meter, it sends electric pulses to the computer. The
computer changes the pulses to a measure in gallons
of water.
[] COMPUTER--The computer is part of the circuit
board. It is programmed to know the softener's
capacity (how many grains of hardness minerals it
will take out of the water before a regeneration is
needed). When starting the softener, page 7, you set
it for the grains per gallon (gpg) hardness of the
water.
To find a regeneration pattern best for your needs,
the computer uses: (1) water usage from the meter,
(2) hardness setting, (3) softener capacity, and (4)
time since the last regeneration. The computer
always adjusts this pattern to your water using habits.
It works toward providing you with soft water for the
longest time and the most efficient salt usage.
Softening capacity is used as hard water goes
through the softener and hardness minerals are
removed, capacity is used. When the computer
determines that only enough capacity remains to
provide soft water up to the next regeneration
starting time (2:00 AM, or as otherwise set) it will
schedule a regeneration. I_CtIARGE TONIGHT
displays until the regeneration begins. When the
regeneration begins, TONIGtIT goes off and -'.'_RE-
(,7lARGE or I_CtlARGE TIME REMAININ(; flashes
during the 2 hour regeneration.
-'._OTE:
If the CLEAN feature is set to ON,
a cleaning
backwash ((,ZEAN and Bbz#sb or Rinse flashes in the
display, along with the minutes of the clean cycle
remaining), precedes the recharge.
