Steca TR 0603mc U
Description
The Steca TR 0603mc U controller was developed specifically for the North American market as a variant of the basic Steca TR 0603mc+ controller. Special approval (ETL mark) via a testing laboratory recognised in the United States as an NRTL (Nationally Recognized Testing Laboratory) means that the relevant safety standards and minimum requirements of the North American market have been met.
In the installation housing, the device connection is created either as a plug & play solution for grid and pump connections or alternatively with 1/2 inch apertures.
As a special highlight, the Steca TR 0603mc U stores the operating data from the system on an SD card. The 40 pre-programmed equipment systems and numerous additional functions facilitate universal use of the controller. The large graphic display shows animated control loops to visualise the operating states of the respective system. Steca TR 0603mc U has six inputs for temperature or pulse detection as well as an additional Grundfos Direct Sensors™ input for combined temperature and flow measurement. Three partially speed-controlled outputs are used to control pumps and switching valves.
