Regeneration types

Softener Metered Immediate:
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 by the feed water
hardness. Softener Immediate systems do not use a reserve volume. The controller will also start a
regeneration cycle at the programmed regeneration time if a number of days equal to the day override
pass before water usage depletes the calculated system capacity. The day override parameter default
is OFF, and REGEN TIME will be greyed out unless the day override value has been modified.
Caution
When setting the system for softener immediate regeneration, setting the capacity to a
value lower than that of feed water hardness may cause the system to constantly
regenerate. If this occurs, disconnect the motor from the controller and correct the capacity
and feed water hardness values in master settings. See 6.2.7. Settings screen, page 59 for
more information.
Softener Metered delayed:
Measures water usage and regenerates the system at the selected regeneration time after the
calculated system capacity is depleted. The control calculates the system capacity by dividing the unit
capacity by the feed water 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. Reserves can be set at a fixed volume,
fixed percentage of capacity, a variable reserve based on the previous calendar day's water usage, or
a weekly reserve based on the average water usage for the current day of the week. The default
setting for the day override parameter is OFF, and the default reserve type is weekly reserve.
A softener delayed controller will also start a regeneration cycle at the selected regeneration time if
a number of days equal to the day override pass before water usage depletes the calculated system
capacity.
If the regeneration type is changed from softener immediate to softener delayed (or vice-versa), all
parameters within those types will be reset to factory default.
Time clock:
Triggers a regeneration on a timed interval. The controller will initiate a regeneration cycle at the
selected regeneration time when the number of days since the last regeneration equals the day
override value. The day override can be set from 1 - 99 days as well as partial day intervals of 4, 8, 12,
16 and 20 hours.
