Steca TR 0603mc+ controller

SKU: 36523641234523
  • The solar thermal controller Steca TR 0603mc+ is the result of a consistent refinement of its highly successful predecessor TR 0603mc. In particular, the EU’s Ecodesign Directive (ErP) has been taken into account in order to control solar thermal pumps with an EEI (Energy Efficiency Index) < 0.23. These energy-efficient, so-called high-efficiency pumps (HE pumps) are controlled by a special PWM control signal.

    The modular controller concept is a special highlight. The 40 pre-programmed configurations and numerous additional functions make for the controller's universal application. Depending on individual needs, the controller can be equipped with additional expansion and heating circuit modules at any time. The large graphic display shows the animated control circuits, which allows you to view the operating statuses of each system. The Steca TR 0603mc+ has six inputs for recording temperatures or pulse values, as well as an extra “Grundfos Direct Sensors™” input for combined temperature and flow rate measurement. HE pumps, standard AC wet pumps, and switching valves are controlled using three outputs, some of which can be speed-controlled.
