The Steca TR 0301 was the first controller on the market to be equipped with a graphic display, on which an animated solar circuit of a solar energy system fully indicates the operating status of the system.
This controller provides everything to operate your solar thermal system safely over a long service life. The Steca TR 0603 controller monitors and controls solar thermal systems with two differently oriented collector arrays and a maximum of two domestic hot water or buffer storage tanks.
As a particular highlight, the Steca TR 0603mc 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 Steca TR 0704 system controller is a universal controller for solar energy and heating systems. In addition to a selection of pre-programmed basic systems, freely programmable individual system configurations can also be realised.
