of hours have elapsed the control will cycle to the fast rinse position for the pre-set length of minutes and
then return to the home or service position.
Down Flow Regeneration
Water and regenerate flow downward through the media tank.
Up Flow Regeneration
Water flow is downward and regenerate flow is upward through the media tank. The significance of this
is that regeneration will be most effective in those parts of the resin bed which are treated with the freshest
regenerate solution. There will tend to be less hardness leakage with up-flow regeneration.

Proportional Brining

The control monitors your softened water usage making only enough brine to regenerate that part of the
resin bed that has been exhausted. In this way the amount of salt used relates directly to the amount of
softened water used, making it more efficient and cost effective. Proportional brining can only be used
with upflow regeneration. The Aqua-Sensor or meter can be used to initiate a regeneration.
Dial-A-Softness
®
Dial-A-Softness is a manual adjustment built into the control valve that allows for variable hardness bypass
into the softened water. The hard water bypass can be adjusted from 0% to 30%. The Dial-A-Softness also
increases the softener capacity in proportion to the percent hard water bypass (less salt used).
