Today many machines in HVAC/R like pumps, fans or compressors have sensors and data interfaces included. Nevertheless, it is still an open question in many cases how those technical features can be used in business cases and contribute finally to the P&L (Profit & Loss) with a financial earning. Technology which is not supporting a business plan is mainly adding cost and not increasing the value generated by a product. In this paper, several proposals are presented on how sensors, data and interfaces (Internet of Things, Industrial Internet) can be used to generate value.
