The animated graphic display and elegant design of the Steca TR 0603 controller make it particularly appealing, allowing it to continue the success enjoyed by this family of controllers.

This controller provides everything to operate your solar thermal system safely over a long service life. The Steca TR 0603 controller monitors and controls solar thermal systems with two differently oriented collector arrays and a maximum of two domestic hot water or buffer storage tanks. The large graphic display shows the animated control circuits, which allows you to view the operating statuses of each system. The clearly arranged display ensures easy operation using pictograms.

15 pre-programmed systems enable universal usage. The Steca TR 0603 controller has six inputs for recording temperatures or pulse values, as well as three speed-controlled outputs for controlling pumps or switching valves.
