Programming the Water Softener.
OPTIONAL CONTROL SETTINGS
The controller display has several options and
features.
LOW SALT ALARM
The LOW SALT ALARM,
when enabled, will
sound the beeper when
the DAYS TO EMPTY
value is 15 days or
less. To change this
setting, press and hold the MODE/SET button for
3 seconds or until you hear a beep. ON (factory
default) or OFF will flash in the display. Press
the UP or DOWN
feature ON or OFF. Press the MODE/SET button
to accept, and the display will move to SALT
EFFICIENCY.
SALT EFFICIENCY
When the SALT
EFFICIENCY feature is
ON, the unit will operate
at a salt efficiency of
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/SET button for 3 seconds. The System
Diagnostics display will appear.
Press the MODE/SET button again and the Salt
Efficiency display will appear.
To change the setting, press the
UP or DOWN
feature ON or OFF. Press the MODE/SET button to
accept.
