The invention relates to a control device for room air managing systems, comprising at least one or more rooms (32, 34) or room zones; an inlet air channel (22) and room inlet air channels (22a) branching therefrom; an exhaust air channel (20) and room exhaust air channels (20 a) branching therefrom; an inlet ventilator (16) in the inlet air channel (22); controllable inlet air throttle flaps (14) for the inlet air flow in the room inlet air channel (20a); and, controllable exhaust air throttle flaps (12) for the exhaust air flow in the room exhaust air channel (22a). According to the invention, there is provided a pressure sensor (38) that detects the room pressure in the room (32, 34) that is to be air conditioned, wherein the room pressure constitutes the direct control parameter for the opening position of the inlet air throttle flap (14) and/or the exhaust air throttle flap (12).
