There are two different types of control panel: 

Power seats without memory 

In vehicles with power seat without memory, the control panel is directly connected to the motors and there is no power seat module (PSM).

Power seats with memory 

In vehicles with power seat with memory, the control panel is integrated in the power seat module (PSM).

A quick way to check if the power seat has a memory function is to look at the control panel. If the seat does not have memory, there are no memory buttons (1-3) or programming button (MEM). The information describes seats with memory, power seat module (PSM) unless otherwise specified.

The controls are used to transmit input signals to the control module from the user: 

The control panel cannot be replaced separately, the entire control module must be replaced in the event of a fault.

There are diagnostics for the control panel.
