SET WATER HARDNESS NUMBER
3. When the display shows your water hardness
(in grains per gallon), press MODE to accept.
NOTE: If there is clear water iron in your water
supply, you will need to increase the hardness
setting by 5 for each 1 ppm of clear water iron
in your water supply.
You can get the grains per gallon (gpg) hardness
of your water supply from a water analysis
laboratory. If you are on a municipal supply,
call your local water department. Or call Legend
Technical Services, an independent laboratory,
to request a water hardness test kit at
1.800.949.8220, option 4. If your report shows
hardness in parts per million (ppm) or milligrams
per liter (mg/l), simply divide by 17.1 to get the
equivalent number of grains per gallon.
SET RECHARGE (STARTING) TIME
1. Press the MODE button until
RECHARGE TIME appears in the
display.
NOTE: A flashing 2:00 AM (factory
default) should show in the display. This is a good
time for recharge to start (takes about 2 hours)
in most households because water is not in use.
HARD WATER is bypassed to house faucets during
recharge.
If no change is needed, go to step 3. To change the
recharge starting time, follow step 2.
2. Press UP
or DOWN
recharge start time. Be sure to observe the AM or
PM as you did when setting the time of day.
NOTE: Each press of a button changes the time by
1 hour. Holding the buttons in changes the time at
a rapid rate.
3. Press the MODE button to accept.

OPTIONAL CONTROL SETTINGS
The controller display has several options and
features.
SYSTEM/ELECTRONIC DIAGNOSTICS
This display contains system
diagnostics information to assist in
troubleshooting problems with the
Water Softener. See page 17.
To access the System Diagnostics, press and hold
the MODE button for 3 seconds.
To return to the normal display, press the MODE
button 2 times.
SALT EFFICIENCY
When the SALT EFFICIENCY feature is ON, the
unit will operate at a salt efficiency of at least 4000
grains of hardness removed per pound of salt. This
mode of operation is the most efficient setting for
salt usage, because the system will tend to recharge
more often, with less salt usage. Turning the feature
OFF will tend to lengthen the time between recharge
cycles, which will provide the most efficient usage
of water, but may use more salt. The degree of
difference between these two cycles is highly
dependent on the water usage and hardness
at a particular installation.
NOTE: California Regulations require this feature to
be ON for installations in California.
To access the Salt Efficiency,
press and hold the MODE
button for 3 seconds. The System
Diagnostics display will appear.
Press the MODE button again and
the Salt Efficiency display will
appear.
To change the setting, press the
UP
or DOWN
ON or OFF. Press the MODE button to accept.
ERROR SIGNALS
If there is an error code detected,
the display will flash Err to signal
that the softener requires service.
See page 16 for information to
assist in troubleshooting error codes. Once the
problem is corrected, disconnect the transformer
from the wall outlet momentarily, and plug it back
in. The normal display will appear. The motor may
run for several minutes, as the unit resets. If the
problem is not corrected, the error code will
reappear in 6 minutes.
