Steca TR 0502 Solar Thermal Controller

Steca TR 0502 Solar Thermal Controller

The new Steca TR 0502 solar thermal controller closes the gap between the already successful Steca TR 0301, TR 0301sc and TR 0603 temperature difference controllers.

With its animated graphic display and elegant design, it continues 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 0502 controller monitors and controls solar thermal systems with up to 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. Pre-programmed systems enable universal usage. The Steca TR 0502 controller has five inputs for recording temperatures or pulse values, as well as two outputs (one is speed-controlled) for controlling pumps or switching valves.
