Abstract
A diagnosis method for the diagnosis of the correct function of a heating and/or cooling system with at least one load circuit (), through which a fluid flows as a heat transfer medium. For the diagnosis an opening degree (V) of the load circuit () is changed for changing the flow. Subsequently a differential pressure (H) across the load circuit () and/or a volume flow of a fluid flowing through the load circuit () is detected and the detected values, or at least a value derived from the detected values, are/is compared to at least one predefined system limit value.
