Steca TR 0603 mc

The Steca TR 0603mc solar thermal controller unites the features of thealready successful Steca TR 0502 and TR 0603 temperature difference controllers.

As a particular highlight, the Steca TR 0603mc stores the system'soperational data on a SD card. The 40 pre-programmed systems andnumerous additional functions allow universal use of the controller.The large graphic display shows the animated control circuits, whichallows you to view the operating statuses of each system. The Steca TR0603mc has six inputs for recording temperatures or pulse values, aswell as an extra Grundfos Direct SensorsTM input forcombined temperature and flow rate measurement. Pumps and switchingvalves are controlled using three outputs, some of which can be speedcontrolled.
