Complete Water Solutions was recently asked to rebuild a Fleck 3900 NT Industrial Water Softener System. One of our recommendations was to upgrade the controllers on the softeners. The customer had the original NT digital controllers on the softener system (2 generations back).
Upgrading the controller on a pre-scheduled plan can help with preventing an unexpected shut down due to controller failure. The new NXT2 controller has a few things to take into consideration when replacing the controller. The biggest thing was to find out the new NXT2 controller is 24V DC – the old controller is 24V AC. So the drive motors are not compatible with the new controller. You will need to replace the drive motors to successfully upgrade to the NXT2.
NXT2 Controller Features

- Additional Diagnostic Displays
