Temperature controller with LCD display TDST24M

thermoelectricfor solar collectors

CONTROL UNIT WITH PWM OUTPUT Centralized control unit for thermal solar panels. Equipped with 3 relay outputs (2 for loads + 1 for alarm), PWM output, 0..10V output and 3 inputs (sensors), can configure and manage up to 6 different types of solar systems. When a specific installation is selected, the control unit automatically manages the outputs and inputs used to control the valves, the pumps, the integrative sources and the probes used in the type of installation selected. Moreover on the backlit LCD display it is possible to visualize the hydraulic diagram of the installation set up, the state of the outputs, the probes as well as several other data and informations.
