The V16 (patent pending 1918133.8) is the upgrade from out V11 range, this video explains how to auto calibrate the controller.
The new features of the V16 include:

PolarityProtect™
This feature means that the V16 will not be damaged if it is wired incorrectly. It simply will not work. Once it has been wired correctly, the unit will recover and work normally.

The advanced pump drive system runs the pump much more smoothly and quietly, and extends its life. With the V16, pumps can be driven slower, faster and harder than ever before.

PumpPrecision™
Thanks to the new pump control technology, the pump is monitored with far greater precision, saving water and energy, and offering faster and more accurate dead end protection.

PumpProtect™
Incorporating features such as dead end detection, pressure switch shutdown, over current detection and short circuit detection, the V16 protects the whole system and helps save power and water.
