The automatic filling switch is a device capable of automatically filling the heating system to the selected pressure.
The use of the switch is also necessary for balancing the pressure drop caused by the extraction of air from the circuit through the air vent valves.
It is usually installed at the entrance of a heating system, between two switches, so that it can be removed without requiring the system to be drained.
It is possible to install the switch with a by-pass to reduce the filling times of the system. In this way, the system is filled 2/3 through the by-pass and the remaining 1/3 through the switch, making it easier to evacuate any potential air bubbles from the system.
