Features of the SXT:
• 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, and tank
in service (twin tank systems only).
• 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 TD.
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.
2. To cancel a queued regeneration, press the Extra
Cycle button.
Regenerating Immediately
Press and hold the Extra Cycle button for five seconds.

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. However, in twin
tank systems with soft-water regeneration, the reserve
capacity should be set to the volume of water used during
regeneration to prevent hard water break-through. 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.
Manually Initiating a Regeneration
1. When timer is in service, press the Extra Cycle button for
5 seconds on the main screen.
2. The timer advances to Regeneration Cycle Step #1
(Backwash), and begins programmed time count down.
3. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #2 (Brine Draw/Rinse).
4. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #3 (Rapid rinse).
5. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #4 (Brine Refill).
6. Press the Extra Cycle button once more to advance the
valve back to in service.
NOTE: If the unit is a filter or upflow, the cycle step order
may change.
NOTE: A queued regeneration can be initiated by
pressing the Extra Cycle button. To clear a queued
regeneration, press the Extra Cycle button again
to cancel. If regeneration occurs for any reason
prior to the delayed regeneration time, the manual
regeneration request shall be cleared.
Control Operation During A Power Failure
The SXT includes integral power backup. In the event of power
failure, the control shifts into a power-saving mode. The control
stops monitoring water usage, and the display and motor shut
down, but it continues to keep track of the time and day for a
minimum of 48 hours.
The system configuration settings are stored in a non-volatile
memory and are stored indefinitely with or without line power.
The Time of Day flashes when there has been a power failure.
Press any button to stop the Time of Day from flashing.
If power fails while the unit is in regeneration, the control will
save the current valve position before it shuts down. When
power is restored, the control will resume the regeneration
cycle from the point where power failed. Note that if power fails
during a regeneration cycle, the valve will remain in it’s current
position until power is restored. The valve system should
include all required safety components to prevent overflows
resulting from a power failure during regeneration.
The control will not start a new regeneration cycle without
line power. If the valve misses a scheduled regeneration due
to a power failure, it will queue a regeneration. Once power is
restored, the control will initiate a regeneration cycle the next
time that the Time of Day equals the programmed regeneration
time. Typically, this means that the valve will regenerate one
day after it was originally scheduled. If the treated water
output is important and power interruptions are expected, the
system should be setup with a sufficient reserve capacity to
compensate for regeneration delays.
