MAXIMUM DAYS BETWEEN REGENERATIONS:
The electronic controller automatically determines
regeneration fre quency. This provides the greatest
operating efficiency and, under most conditions this
feature will be left in its default mode. However,
you can set this feature to force a regeneration
every set number of days. You may want to do this
if, for exam ple, your water supply contains iron and
you want the softener to regenerate at least once
every few days to keep the resin bed clean. Use
s
the UP or DOWN buttons to change the
number of days (up to 15).

ON, the regeneration can occur at any time (when-
ever the system has reached 97% of its capacity).
The default is OFF. If this feature is desired, turn it
