Seitron solar control unit with PWM output ELIOS MIDI TDST24M

Seitron solar control unit with PWM output ELIOS MIDI TDST24M Control unit for thermal solar panel systems. Equipped with 3 relay outputs (2 load + 1 alarm), one PWM output, one 0..10V output and 3 inputs (probes), it can configure and manage up to 6 different types of solar systems.
By selecting one of the 6 system diagrams, the control unit will automatically manage the outputs and inputs related to the chosen system type.
Furthermore, the backlit LCD display will show the configuration of the system's hydraulic diagram, the status of the outputs, the status of the probes, and many other pieces of information and data.
