Timer Features Parameter Display Data Display PM Indicator Error/ Information Icon Flow Indicator Service Icon x1000 Indicator Programming Icon Extra Cycle Button Up Button Down Button 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.
Timer Features 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.
Timer Operation 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.

Master Programming Mode When the Master Programming Mode is entered, all available option setting displays may be viewed and set as needed. Depending on current option settings, some parameters cannot be viewed or set.. . 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.
Master Programming Mode 2. Valve Type (Display Code VT) Press the Extra Cycle button. Use this display to set the Valve Type. The Valve Type setting specifies the type of cycle that the valve follows during regeneration. Note that some valve types require that the valve be built with specific subcomponents. Ensure the valve is configured properly before changing the Valve Type setting. This option setting is identified by “VT” in the upper left hand corner of the screen.
Master Programming Mode 5. Tank in Service (Display Code TS) Press the Extra Cycle button. Use this display to set whether tank one or tank two is in service. This option setting is identified by “TS” in the upper left hand corner of the screen. This parameter is only available if the number of tanks has been set to 2. There are two possible settings: Tank One in Service: Tank Two in Service: U1 U2 6. Unit Capacity (Display Code C) Press the Extra Cycle button. Use this display to set the Unit Capacity.
Master Programming Mode 8. Reserve Selection (Display Code RS) Press the Extra Cycle button. Use this display to set the Safety Factor. Use this display to select the type of reserve to be used in your system. This setting is identified by “RS” in the upper left-hand corner of the screen. The reserve selection parameter is only available if the control type has been set to one of the metered options. There are two possible settings. FS Safety Factor rc Fixed Reserve Capacity . . . . . 9.
Master Programming Mode 11. Day Override (Display Code DO) Press the Extra Cycle button. Use this display to set the Day Override. This setting specifies the maximum number of days between regeneration cycles. If the system is set to a timer-type control, the day override setting determines how often the system will regenerate. A metered system will regenerate regardless of usage if the days since last regeneration cycle equal the day override setting.
Master Programming Mode 14. Day of Week Settings Press the Extra Cycle button. Use this display to set the regeneration schedule for a system configured as a Day of Week control. The different days of the week are identified as D1, D2, D3, D4, D5, D6, and D7 in the upper left-hand corner of the display. Set the value to “ON” to schedule a regeneration or “OFF” to skip regeneration for each day. Use the Up and Down buttons to adjust the setting as needed.
Master Programming Mode 17. Meter Pulse Setting (Display Code K) Press the Extra Cycle button. Use this display to specify the meter pulse setting for a non-standard flow meter. This option setting is identified by “K” in the upper left-hand corner of the screen. Use the Up and Down buttons to enter the meter constant in pulses per unit volume.. . . . 18. Press the Extra Cycle button to save all settings and exit Master Programming Mode.
