— it is a system that controls the temperature in the heating circuit. When the coolant temperature drops below 5 °C, the burner is ignited, the circulation pump is activated, and the circuit warms up until a temperature of about 35 °C is reached. Thus, it prevents the formation of ice in the pipes, which otherwise could lead to rupture of the pipes.
