Central unit receives weather forecast and electricity spot price information from our cloud service with your home internet connection. Together with these and your home characteristics, it then optimizes your heating. It controls heating by sending wireless commands to control relay, which is connected to the power supply of your heating equipment. Temperature sensor measures your home temperature and sends it wireless to the central unit. With direct electricity heating, your home temperature is controlled with the help of measured temperature. With waterborne underfloor heating, measured temperature is only indicated in your user interface.
