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.

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.

The new TR 0603mc solar thermal controller stores the system’s operational data on an SD card.

The 28 pre-programmed systems and numerous additional functions allow universal use of the controller. The large display panel shows the animated control circuits, which allow you to view the operating conditions of each system. The TR 0603mc also has 6 inputs for recording temperature or pulse values, as well as an extra „Direct Sensor“ input for combined temperature and flow rate measurement. Pumps and switching valves are controlled using 3 outputs, some of which can be RPM controlled.

Down Load Data Sheet 7.3MB

The Steca Internet remote display allows permanent monitoring and performance analysis of one or more solar energy systems. The Steca TK RW2 IFA router allows visualisation of the operation of solar thermal systems: Temperature and performance data are clearly displayed for analysis in an Internet browser window.



This works in a simple way: The Steca TR 0603mc solar thermal controller cyclically sends measurements to the IFA router. The Steca TK RW2 processes the data and forwards it to a central server. The server archives this information and presents it visually in the Internet - as system images, graphics, tables, diagrams and even as a slide slow. These visualisations can also be sent from the IFA router to a digital picture frame via the WLAN interface.

The Steca TE A603 expansion module facilitates modular expansion of the Steca TR 0603mc and Steca TH A603 M system controllers. Optional functions and system expansions allow these system controllers to be adapted individually to the system to be controlled.


The Steca TE A603 includes six inputs for recording temperatures or pulse values as well as an additional Grundfos Direct SensorsTM input for combined temperature and flow rate measurement. Pumps and switching valves are controlled using three outputs, some of which can be speed controlled. Up to three Steca TE A603 expansion modules can be connected as bus slaves via the Steca TPC 1 bus to the Steca TR 0603mc or Steca TH A603 M system controller. The user friendly menu of the system controller is not only used to adjust all functions and parameters of the expansion module, but also monitor while it is running. Four LEDs provide information on the operating status of the expansion module.
