The AAV removes air bubbles that are present within a central heating system, ensuring that the system does not become airlocked. Unlike most components within a boiler, the AAV does not need to receive signals from the PCB to activate. A float within the AAV monitors the system water level and allows air to be vented. When the water level is high, the air discharge hole is blocked by the float, if the water level is low, air can escape as the discharge hole is no longer blocked.
