• and a control module comprising an elongated housing comprising a first housing end portion and an opposing second housing end portion delimiting the housing in the longitudinal direction and an envelope surface there between delimiting the housing in the radial direction,
• wherein the first housing end portion comprises a second connector connectable to the main body,
• wherein the control module comprises at least one through opening in the envelope surface extending from an inner space in the housing to an outside of the envelope surface and a flexible seal ring configured around the outside of the envelope surface covering the at least one through opening, wherein an air pressure in the housing is regulated by the flexible seal ring.
