Description

The Steca TR 0402 solar thermal dual-circuit controller meets the requirements of modern solar energy systems‘ fundamental layouts. In particular, alongside single-circuit solar energy systems, this includes so-called „combined solar energy systems“ which can also use the sun‘s energy for heating. Combined solar energy systems are either 2 storage tank systems, or a combined storage tank system in which one „combined“ storage tank provides hot water for heating, as well as hot drinking water.

By means of its numerous and additionally selectable functions, the Steca TR 0402 controller enables individual system adjustment. Thus, for example, the heating return can be integrated into the solar energy system, or the back-up heating or circulation pump can be controlled directly from the solar controller.

The large animated graphic display visualises the operating statuses, and shows not only the current temperature, but also the minimum and maximum temperature values. The Steca TR 0402 controller‘s features also include display of the operating hours and a calculated heat quantity. The preprogrammed systems and the consistent use of easy-tounderstand pictograms guarantee that the controller is simple to operate.

In addition, comprehensive information windows are displayed, so as to continually ensure reliable operation of the solarenergy system, and to provide detailed information at all times.
