Abstract: Plug-in connection, comprising a plug-in connector (1) which can be plugged together with a mating plug-in connector, also known as a pin housing (2), it being possible to at least indirectly lock the plug-in connector (1) with the mating plug-in connector (2), characterised in that a bushing housing (3) is provided which at least partially surrounds the plug-in connector (1) and provides the locking with the mating plug-in connector or pin housing (2), and in that the plug-in connector (1), the mating plug-in connector or the pin housing (2) and the bushing housing (3) are operatively interconnected by means of a lever mechanism and can be braced together.

Abstract: Plug connection with a plug connector (2) and a mating plug connector (3), which form a male connector and a female connector and can be latched with one another, at least indirectly, characterized by a housing (1) in which a plug connector (2) can be inserted and fixed and in which a space for receiving a mating plug connector (3) is provided, and by a housing cover (4) which is pivotably mounted on the housing (1) and has locking and unlocking elements which are spaced apart from the pivot bearing and which can be brought into contact with supporting elements on the mating plug connector (3).

Abstract: A control unit for an air conditioning system is designed to operate one or more actuators of the air conditioning system automatically in an automatic operating mode in order to set reference ambient conditions in a chamber. The control unit is configured to detect that an automatic change has occurred in an operating state of an actuator of the air conditioning system. The control unit is further configured to output via a user interface of the air conditioning system, information relating to the automatic change in the operating state of the actuator.
