Time Clock Delayed Control
The 2510 AIO SXT uses a Time Clock Delayed control, which
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.
Regeneration Steps
Backwash (BW) Cycle Step #1
The Backwash cycle washes oxidized contaminates to drain
and reclassifies the media bed.
Air Draw (BD) Cycle Step #2
Air Draw empties water from tank and replenishes oxygen to
filter media.
Rapid Rinse (RR) Cycle Step #3
Rapid Rinse purges excess atmosphere from the media tank
and distributor.

Manually Initiating a Regeneration
1. When timer is in service, press the Extra Cycle button for
five seconds on the main screen.
2. The timer advances to Regeneration Cycle Step #1
(backwash), and begins programmed time countdown.
3. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #2 (air draw).
4. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #3 (rapid rinse).
5. Press the Extra Cycle button once more to advance the valve
back to service.
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 display
and motor shut down, but the control 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 its 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.
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.
