Why does my Sterling Water Filtration System regenerate at the wrong time?

  Tony CastilloAug 18, 2025
  If your Sterling Water Filtration System is regenerating at the wrong time, it could be due to: * A past power outage, so you should reset the time of day. * An incorrect time of day displayed, so you should reset the time of day. * The time of regeneration being set incorrectly, so you should reset the time of regeneration. * The control being set at "on 0", so you should check the regeneration time option in programming. * The control being set at "NORMAL + on 0", so you should also check the regeneration time option in programming.
