TBM fuel selector question

[B350ATP]

Just curious, but I see the big circular fuel selector in the TBM cockpits, is the system automatic or does the pilot (aka Piper Cherokee style) have to manually select tanks.

Thank You

From the manual

3 - Fuel
- Gages ........................................ CHECK
REGULARLY CHECK :
- consumption
- tank automatic change (every10minutes)
- symmetry [max. dissymmetry 25 us gal(95Litres)]

There's a servo motor that automatically switches tanks every 15 minutes.
