The program is used for graphic-aided design of cold, hot and circulating water installations in traditional, serial, tee and manifold systems in residential and public buildings. It also allows the selection of thermostatic valves in circulation systems.

The program is used to support graphic-aided design of new installations  of radiator and underfloor central heating. It also  supports the regulation of already existing installations (for example in buildings insulated) in residential and public buildings. The program also allows the design of pipe networks in ice water installations.

The program is used to support the calculation of the heat load in rooms. In Audytor HL (OZC) designers can create 3D models of buildings and perform heat load calculations, and then apply results of their work designing heating systems.

Program performs quick selection of radiators and underfloor central heating in residential and public buildings. It gives the ability of reviewing the technical data of chosen equipment. The program is especially recommended for quick selection of equipment for the purpose of their valuation.
