💧 QA Režim TUV

QA Režim TUV is an intelligent application for managing hot water heating using multiple types of heat sources, such as solar collectors, photovoltaics, heat pumps, gas boilers, or mains electricity. It automatically selects the most cost-effective available source based on time schedule, annual heating mode, outdoor temperature, and predicted daily solar irradiance. Setting heating priorities enables you to achieve maximum savings while meeting your temperature requirements.

💼 Business presentation

The application combines information about seasonal conditions, solar forecasts, and source availability, enabling intelligent decisions about when to use solar collectors, when to use photovoltaic surpluses, and when to use a gas boiler, for example. In winter months, it may prefer the boiler for quick heating, while in summer it maximizes the use of photovoltaic surpluses. All sources and their priorities are fully configurable.

📊 Analysis and data management

For clear visualization, measurement history management, and graphs, we recommend integration with SCADA Mervis.
