I have put together this short video of how to set the auto calibration on the 3 button 3 digit range of pump controls.

As a general rule the suggestion would be to re calibrate the controller if you change the hose pump or fittings on your system. Set the calibration with the longest pole attached with water flowing.

Hope this helps
