The present invention relates to an arrangement in a control unit (1) for a plurality of sub-systems, each comprising one or more sub-system components and forming part of an air conditioning system intended for vehicles, especially buses. The control unit (1) has, for each sub-system, a separate selection device (2, 3, 4, 5, 6) intended, when it is pressed, to connect ea ch separate component in a first group of controllable components of the select ed sub-system to an associated set of operating controls (7, 8, 9, 10), so that the components in the first group can be controlled by way of the operating controls. The number of operating controls in the set defines the size of th e group. The invention is characterised in that there is at least one separate selection device (11), which when pressed will connect at least some of the operating controls (7, 8, 9, 10) in the set to a group of sub-system components specially selected for rapid access. At least some of the sub- system components in this specially selected group derive from different sub - systems.
