Regeneration Types
The XTR3 control supports several different Regeneration Types. The Regeneration Type defines the method of automatic
regeneration for the system. Each type is explained below.
Time Clock
Triggers a regeneration on a timed interval. The control 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.
Softener 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 control 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 grayed 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
control and correct the capacity and feed water hardness values in Master Settings.
Softener 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 for the day override parameter is OFF, and the default reserve type is Weekly Reserve.
A Softener Delayed control 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 regen type is changed from Softener Immediate to Softener Delayed (or vice-versa), all parameters within those types will
be reset to factory default.
