Festool CTL26 Connectors on PCB

[PeterPorter]

I recently picked up an 2016 110v Festool CTL26 full of plaster dust. When I was disembling and cleaning it I noticed the PCB has two 5 pin connectors and a rotating control that aren't used. Anyone know what these are for? They're separate from the connectors behind the accessory panel.
I'm wondering if they're for something that I could make use of.

My guess would be connections for different voltages in different countries.

I don't know the answer, but might they be related to the option to fit the compressed air tool module?
