CONTROL ADJUSTMENTS
DETERMINING CAPACITY
Refer to the specification table (page 2) for exchange capacity of
each model based on salt dosage.
9500E Models only – The operational mode for this group is metered
immediate. In this case, "reserve capacity" is not required.
2900E-DP, 2900E-TP, 2900E-QP, 3900E-300-NHWB, and
3900E-450-NHWB Models only –The operational mode for this
series can vary based on the application. In most cases, the
system will operate in meter immediate mode, (system 14), so the
regeneration occurs as needed, on only one tank at a time.
PROGRAMMING
2850E, 2900E, 2900E-DP, 2900E-TP, 2900E-QP and 3900E
Models only
Refer to the "3200NXT2 Timer Service Manual" and associated
inserts for detailed programming information. A table has been
provided on page 11–12 to assist with programming specific time
intervals based on model and system capacity.
2850E, 2900E, 2900E-DP, 2900E-TP, 2900E-QP and 3900E Models only
1. Press and hold the Left and Down buttons simultaneously for 3
seconds to enter Master Programming mode.
2. To navigate, press the Extra Cycle button to advance to the next
value. Press the Left button to retreat to the previous value.
3. Where applicable, use the Down and Up buttons to adjust a
value as desired. When entering data into text fields (such as
Assistance Name) or numerical fields (such as Hardness), press
the Extra Cycle button to advance to the next character/digit and
press the Left button to retreat to the previous character/digit.
Proceed through all available characters/digits to advance to the
next value.
4. To reset/clear a value (such as Assistance Name), while on the
value, press and hold the Down and Up buttons simultaneously
for 5 seconds.
NOTE: Refer to page 9 of the "Pentair Fleck NXT2 Timer Service Manual" for more detailed information
WITH SOFTENER VALVE CONTROL SETTINGS
The following table includes the recommended time durations
for each regeneration step. These values are based on a typical
application. Under certain conditions, these values may require
some adjustment. Refer to the performance specifications table
on page 2 to determine the usable capacity of the system, based on
salt dosage. A detailed description of the "Brine Rinse" and "Brine
Tank Refill" time settings has been outlined below:
Min. – Minimum system capacity – based on 6 lbs (2.72 kg) of salt per Ft
Med. – Medium system capacity – based on 9 lbs (4.1 kg) of salt per Ft
Max. – Maximum system capacity – based on 15 lbs (6.8 kg) of salt per Ft

only – The operational mode for all single softeners is system 4 -
meter delayed. The unit should be programmed to regenerate at an
off-peak time period, such as 2:00 AM. Since this type of system
only examines the need to regenerate once every 24 hours, a
"reserve capacity" is automatically calculated. The NXT2 controller
automatically calculates the reserve capacity and adjusts based on
daily usage.
NOTE: 2900E-DP, 2900E-TP, and 2900E-QP Models only –
The programming of each control varies slightly. One control is
programmed as the "LEAD" and the other as the "LAG".
9500 Models only: See pages 13–14. Master Programming Mode
5. To exit Master Programming Mode, progress through all
available values or after 5 minutes of inactivity the timer will
exit automatically. To exit master programming without saving
changes, press the Left button until you return to the service
screen.
6. Depending on the current controller programming, certain
values may not be able to be viewed or set.
7. The timer will display local information, not system information.
8. In the event of a regeneration occurring while displaying master
programming, the regeneration step and time remaining will be
displayed. When regeneration has been completed, the display
will return to the main screen.
