Regeneration flows
Metered immediate control
A meter immediate control measures water usage and regenerates the system as soon as the
calculated system capacity is depleted. The control calculates the system capacity by dividing the
unit capacity (typically expressed in °TH*m
3
volume) by the feedwater hardness and subtracting
the reserve. Meter Immediate systems generally do not use a reserve volume. A Meter Immediate
control will also start a regeneration cycle at the programmed regeneration time if a number of
days equal to the regeneration day override pass before water usage depletes the calculated
system capacity.
Metered delayed control
A Meter Delayed Control measures water usage and regenerates the system at the programmed
regeneration time after the calculated system capacity is depleted. As with Meter Immediate
systems, the control calculates the system capacity by dividing the unit capacity by the feedwater
hardness and subtracting the reserve. The reserve should be set to ensure that the system
delivers treated water between the time the system capacity is depleted and the actual
regeneration time. A Meter Delayed control will also start a regeneration cycle at the programmed
regeneration time if a number of days equal to the regeneration day override pass before water
usage depletes the calculated system capacity.
Time clock delayed control
A Time Clock Delayed Control regenerates the system on a timed interval. The control will initiate
a regeneration cycle at the programmed regeneration time when the number of days since the
last regeneration equals the regeneration day override value.
Day of the week control
This control regenerates the system on a weekly schedule. The schedule is defined in Master
Programming by setting each day to either “OFF” or “ON.” The control will initiate a regeneration
cycle on days that have been set to “ON” at the specified regeneration time.
