The required flow of the individual radiators is set directly on the thermostatic valve base Eclipse. This means that the hydraulic adjustment is done with one turn. The set flow rate is not exceeded. This means that even in the event of an oversupply, e.g. due to closing neighboring valves or during the morning warm-up phase, Eclipse automatically regulates the flow to the set value. The valve regulates the flow regardless of the differential pressure. Complex calculations to determine the setting values are therefore not necessary.
