Features of the SXT(4002217):
• Power backup that continues to keep time and the passage
of days for a minimum of 48 hours in the event of power
failure. During a power outage, the control goes into a
power-saving mode. It does not monitor water usage
during a power failure, but it does store the volume
remaining at the time of power failure.
• Settings for both valve (basic system) and control type
(method used to trigger a regeneration).
• Day-of-the-Week controls.
• While in service, the display alternates between time of
day, volume remaining or days to regeneration.
• The Flow Indicator flashes when outlet flow is detected.
• The Service Icon flashes if a regeneration cycle has been
queued.
• A Regeneration can be triggered immediately by pressing
the Extra Cycle button for five seconds.
• The Parameter Display displays the current Cycle Step
(BW, BF, RR, etc) during regeneration, and the data
display counts down the time remaining for that cycle
step. While the valve is transferring to a new cycle step,
the display will flash. The parameter display will identify
the destination cycle step (BW, BF, RR, etc) and the data
display will read "----". Once the valve reaches the cycle
step, the display will stop flashing and the data display will
change to the time remaining. During regeneration, the
user can force the control to advance to the next cycle step
immediately by pressing the extra cycle button.
Setting the Time of Day
1. Press and hold either the Up or Down buttons until the
programming icon replaces the service icon and the
parameter display reads DO.
2. Adjust the displayed time with the Up and Down buttons.
3. When the desired time is set, press the Extra Cycle button
to resume normal operation. The unit will also return to
normal operation after 5 seconds if no buttons are pressed.
Queueing a Regeneration
1. Press the Extra Cycle button. The service icon will flash to
indicate that a regeneration is queued.

TIMER OPERATION

Meter 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 grains/
unit 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.
Meter 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 insure
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 initiates a regeneration
cycle on days that have been set to "On" at the specified
regeneration time.
Control Operation During Regeneration
During regeneration, the control displays a special regeneration
display. In this display, the control shows the current
regeneration step number the valve is advancing to, or has
reached, and the time remaining in that step. The step number
that displays flashes until the valve completes driving to this
regeneration step position. Once all regeneration steps are
complete the valve returns to service and resumes normal
operation.
Pressing the Extra Cycle button during a regeneration cycle
immediately advances the valve to the next cycle step position
and resumes normal step timing.
Control Operation During Programming
The control only enters the Program Mode with the valve in
service. While in the Program Mode, the control continues
to operate normally monitoring water usage and keeping all
displays up to date. Control programming is stored in memory
permanently, eliminating the need for battery backup power.
