LEVEL III CYCLE PROGRAMMING
C Values
Several Level III program parameters can be adjusted to fine-
tune valve operation for non-standard applications. Typically
these parameters will not need to be adjusted as the default
settings accommodate most applications. Contact your water
treatment professional before attempting any programming.
The parameters are accessible by pressing and holding the UP
and SET buttons until the display shows a “C” value.
NOTE:
The control must be in the treated water position to
change settings.
