KG offers an app to support the execution and documentation of the hydronic balancing of heating systems. Whether on the construction site, at a consultation appointment or in the office, users of the OVapp can calculate the preset values of the Oventrop thermostatic valves and regulating and pipeline valves at any time with their smartphone or tablet and thus easily carry out the hydronic balancing of heating systems. In addition, a simplified heating load calculation according to DIN EN 12831-B3 or a radiator sizing with DIN radiators is integrated. The OVapp can be used to fulfil the requirements of procedure A and B of the VdZ form (individual measure) for hydronic balancing within the framework of the Federal Funding for efficient buildings (BEG) for existing buildings - procedure B is possible when using the Q-Tech thermostatic valves with flow control. The calculations can be documented using a PDF file or WLAN printer. The VdZ form is filled out automatically according to the designs. Furthermore, the OV-DMC 3 measuring system for the adjustment and control of heating and cooling systems is integrated. Pressure measurements can be carried out easily with the OVapp and the measuring sensor, flow values can be determined and presettings for the desired volume flows can be determined. With the ErP wizard there is the possibility to create ErP energy efficiency labels as composite labels for Oventrop products in the field of solar thermal energy. Furthermore, an extensive manufacturer product database of the VdZ with ErP-relevant products can be accessed.
