The XT advanced electronic controller is availablie for single control valve operation. The XT can be configured to the Fleck® 2510, 2750, 2850, 2900, 3150, 3900, 9000, 9100 and 9500 valves.

In Time Clock Delay mode, the XT will display the number of days until the next scheduled regeneration. Some meter delated types will display the volume remaining (SRV) minus the reserve. Once the volume remaining is zero, the display will start counting down the reserve volume and queue (RGQ) regeneration

The same SXT control drives 6 different Fleck valves, saving you time in installation, service and training.

Unlike other electronic valves, the SXT control performs without switching out cams or fumbling with jumpers, pins and cryptic calculations.

A large backlit LCD display alternates between time of day, soft water remaining or days to regeneration, and tank in service (twin tank systems only). Fleck valves using an SXT control is the best entry-level solution for all your residential water treatment applications.
