The system device is connected to the flat solar collectors and to the bottom of the solar heat storage via temperature sensors. In this way the system device calculates the solar thermal energy level of the solar collectors and operate the circulation pump to circulate water as long as there is solar thermal energy to retain from the flat solar collector. When there is insufficient solar energy levels or danger of frost or if the solar collectors have acheived temperatures close to the boiling point, the circulation is stopped and the water draines out of the solar collector and back into the drain-back storage.

The system device is particularly adapted to our flat solar collector and the system design used in our solar thermal energy systems. The system device has been developed in close cooperation with the RESOL the leader within the field of such devices in the world. The system device ensures consistent and optimal circulation in the solar collectors.
