Level lll Cycle Programming – C Values
Several Level III program parameters can be adjusted
to fine-tune a conditioner's 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.
