SXT Controller Programming and Operation
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 trans-
ferring 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 pro-
gramming 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.
Manually Initiating 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.
