During a power outage, the control goes into a power-saving mode. It does not monitor waterusage 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, andtank 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 datadisplay 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 thedata display will read “----”. Once the valve reaches the cycle step, the display will stop flashing and the datadisplay will change to the time remaining. During regeneration, the user can force the control to advance tothe next cycle step immediately by pressing the extra cycle button.Setting the Time of Day1. Press and hold either the Up or Down buttons until the programming icon replaces the service icon and theparameter 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 alsoreturn to normal operation after 5 seconds if no buttons are pressed.Page 4

Timer OperationMeter Immediate ControlA meter immediate control measures water usage and regenerates the system as soon as the calculated systemcapacity is depleted. The control calculates the system capacity by dividing the unit capacity (typically expressedin grains/unit volume) by the feedwater hardness and subtracting the reserve. Meter Immediate systems generallydo not use a reserve volume. However, in twin tank systems with soft-water regeneration, the reserve capacityshould be set to the volume of water used during regeneration to prevent hard water break-through. A MeterImmediate control will also start a regeneration cycle at the programmed regeneration time if a number of daysequal to the regeneration day override pass before water usage depletes the calculated system capacity.Meter Delayed ControlA Meter Delayed Control measures water usage and regenerates the system at the programmed regenerationtime after the calculated system capacity is depleted. As with Meter Immediate systems, the control calculates thesystem capacity by dividing the unit capacity by the feedwater hardness and subtracting the reserve. The reserveshould be set to insure that the system delivers treated water between the time the system capacity is depletedand the actual regeneration time. A Meter Delayed control will also start a regeneration cycle at the programmedregeneration time if a number of days equal to the regeneration day override pass before water usage depletesthe calculated system capacity.Time Clock Delayed ControlA Time Clock Delayed Control regenerates the system on a timed interval. The control will initiate a regenerationcycle at the programmed regeneration time when the number of days since the last regeneration equals theregeneration day override value.Day of the Week ControlThis control regenerates the system on a weekly schedule. The schedule is defined in Master Programming bysetting 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 RegenerationDuring regeneration, the control displays a special regeneration display. In this display, the control shows thecurrent 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 allregeneration 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 cyclestep position and resumes normal step timing.Control Operation During ProgrammingThe control only enters the Program Mode with the valve in service. While in the Program Mode, the controlcontinues to operate normally monitoring water usage and keeping all displays up to date. Control programming isstored in memory permanently, eliminating the need for battery backup power.Manually Initiating a Regeneration1. 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 (rapid rinse), and begins programmed time count down.3. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #2 (backwash).4. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #3 (brine draw & slow 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 queuedregeneration, press the Extra Cycle button again to cancel. If regeneration occurs for any reason prior to thedelayed regeneration time, the manual regeneration request shall be cleared.Page 6

Timer OperationControl Operation During A Power FailureThe SXT includes integral power backup. In the event of power failure, the control shifts into a power-savingmode. The control stops monitoring water usage, and the display and motor shut down, but it continues to keeptrack 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 withoutline power. The Time of Day flashes when there has been a power failure. Press any button to stop the Time ofDay 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. Notethat 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 powerfailure during regeneration.The control will not start a new regeneration cycle without line power. If the valve misses a scheduledregeneration due to a power failure, it will queue a regeneration. Once power is restored, the control will initiatea 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 isimportant and power interruptions are expected, the system should be setup with a sufficient reserve capacity tocompensate for regeneration delays.Page 7
