Setup Instructions for Fleck SXT Filter Controls.
These instructions apply to all SXT-controlled filters, but not softeners. AIO (Air Induction, Single Tank Aeration) Filters are not included.
To enter master programming:
Use the up and down buttons to set the time of day to 12:01 PM. Must be PM. Then press the “Extra Cycle” button–the button on the left–to save the time.
With the time set to 12:01 PM, press the Up and Down buttons simultaneously and hold for 5 seconds (until the display changes). You are now in Master Programming Mode. The display should show GAL.
Use the Extra Cycle button to advance through the various programming stages. Pressing the button saves the setting on the screen and advances to the next item.
| Display | Explanation | Set your unit to |
| DF | Display Format | GAL (for gallons) |
| VT | Valve Type | Flt (for filter). This is an important setting. Don’t choose anything else. |
| CT | Control Type | tc (for Time Clock). |
| NT | Number of tanks | 1 |
| DO | Day Override | This feature determines the frequency of regeneration. Set to 1 for daily regeneration, 2 for every-other day, 3 for every third day, etc. |
| RT | Regeneration Time | Set to the time you want the unit to regnerate. For example, 2:00 AM. |

The display will alternate between the time of day and the number you put in the Day Override setting. Reset the time to the actual time of day. The Day Override number will count downward one number per day until the day of the regeneration is reached, then it will reset itself.
When the filter is in service you can begin a regeneration at any time by pushing and holding the Extra Cycle Button for 5 seconds.
