Programming the Control
CONTROL SETTINGS REQUIRED upon installation and

ELECTRICAL OUTLET, 12:00 PM (flashing), and PRESENT
TIME is displayed. Program the control as instructed below.

by the correct code number, use the DOWN button.
Then press the MODE button to accept the correct model.

a change from the button you have pressed, and you should
select another button.

SET PRESENT TIME OF DAY
1. Press the MODE button until PRESENT
TIME appears in the display.
2. Press UP or DOWN button to set.
The UP button advances the time; the
DOWN button moves the time in reverse.
2. If the present time is between noon and midnight, be sure
PM shows in the display. If the present time is between
midnight and noon, be sure AM shows in the display.
NOTE: Each press of an UP or DOWN button changes
the time by one minute. Holding the button changes the time
at a rapid rate.
3. When the present time is correct, press MODE to accept.
SET WATER HARDNESS NUMBER
1. Press the MODE button until
HARDNESS appears in the display.
2. Press UP or DOWN button to set your water hardness
number in the display. DOWN decreases the hardness value.
UP increases the hardness value.
NOTE: Each press of a button changes the display by 1, between
1 and 25. Above 25, the display changes 5 at a time (25, 30, 35,
etc.). Holding a button in changes the numbers at a rapid rate.
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 1.800.826.8553, extension
47. 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 button to set the desired 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.
