The STA-W module is an interface designed for the exchange of heat quantity measurement values between RESOL devices and external appliances. It can be connected to a RESOL controller or a calorimeter via the VBus. Whenever the heat quantity increases by 1 kWh, the module operates a potential-free contact which is connected to the central building management system. The total number of operated contacts can be visualised as heat quantity by the software of the central building management system.
