tSol is a specialized device, controlling the heat exchange between solar collector and boiler. It provides optimal control of the process as well as monitors for emergencies thus preventing extreme and dangerous conditions.

The device monitors the temperatures of the solar collector and the boiler so when the conditions of the control logic are met, the heat energy generated in the solar collector is transferred towards the boiler through the circulation pump. tSol has flexible control loop that can be modified through adjustable parameters and the specifics of every system can be met.

The device also has a built-in thermostat, that controls the additional boiler heating be it an electrical heater or other heat source independently from the pump. Mounting a third thermal sensor in the upper boiler part reads the real hot water temperature.
