Anexample of a time with low waterusage is when a household is asleep.If there is a demand for water when the system is regenerating,untreated water will be used.When the system begins to regenerate, the display will changeto include information about the step of the regeneration processand the time remaining for that step to be completed. The systemruns through the steps automatically and will reset itself to pro-vide treated water when the regeneration has been completed.MANUALREGENERATIONSometimes there is aneed to regeneratethe system, soonerthan when the system calls for it, usually referred to as manualregeneration. There may be a period of heavy water usagebecause of guests or a heavy laundry day.To initiate a manual regeneration at the preset delayed regener-ation time, when the regeneration time option is set to “NORMAL”or “NORMAL + on 0”, press and release “REGEN”. The words“REGEN TODAY” will flash on the display to indicate that the sys-tem will regenerate at the preset delayed regeneration time. Ifyou pressed the “REGEN” button in error, pressing the buttonagain will cancel the request.
