6 inputs, 3 outputs
- Compact, multipart designer casing
- Multifunction graphical LC display with backlighting
- Animated representation of the systems and operating states
- Multilingual menu navigation




Description
The Steca TR 0603mc U controller was specially developed for the North American market based on the Steca TR 0603mc basic controller. With its special certification (ETL label) from a Nationally Recognized Testing Laboratory (NRTL) in the US, the controller meets the safety standards and minimum requirements of the North American market.
The equipment is connected inside the installation casing using either a plug & play solution for the mains and pump connections or alternatively 1/2 inch cut-outs.
As a particular highlight, the Steca TR 0603mc U stores the system's operational data on a SD card. The 40 pre-programmed systems and numerous additional functions allow universal use of the controller. The large graphic display shows the animated control circuits, which allows you to view the operating statuses of each system. The Steca TR 0603mc U 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. Pumps and switching valves are controlled using three outputs, some of which can be speed controlled.
