NIB Steca TR 0301 U Solar Temperature Differential Controller tested

This is a new Steca TR 0301 U solar controller, presented in a beige housing with a black display and buttons. It includes a power cord with a two-prong plug, two temperature sensors, and a small bag of mounting hardware. The unit features a digital display showing a schematic, and control buttons for "SET" and up/down arrows. The back of the unit has mounting points and a warning label regarding hazardous voltage. The controller is packaged in its original brown cardboard box.

This item is new but the box has been opened and has some small damages to it, as well as possible papers missing. The item itself is in brand new condition along with its cords and powers on as it should. This item was tested to ensure it does power on and the display shows properly.
