"No DIP switches" and "automatic" are very different ideas. The Samlex controller has those switches for configuration, and then operates automatically. The GoPower controller has no switches and uses front panel buttons and a screen for configuration, then operates automatically. So... both require manual configuration, and both feature automatic operation (they change charging voltage by themselves as the battery charges).
It would be possible to build a controller which configures itself to suit the attached battery, so it would both configure
automatically, but the GoPower GP-PWM-30 does not work that way; configuration is not automatic.
