This standard applies to the design of new and the mathematical verification of existing heating and cooling water distribution systems, with the specific purpose of verifiably establishing the hydraulic balancing in the design state using regulating resistors or automatically acting balancing valves. The hydraulic balancing minimizes the thermal and electrical costs. Sufficient valve authority of the control valves plays a decisive role for the control capability. In practice, there are different technical solutions for this, which are dealt with in detail in this standard. Not considered are e. g. temperature-based control systems.
