By accurately managing the mixing of supply and return water

preventing the common short-cycling issues caused by worn bimetal sensors or fouled pilot orifices

this vent effectively manages air elimination to prevent air binding and pump cavitation

allowing it to function efficiently in both cooling and heating cycles without needing a separate bypass check valve

This configuration is essential for modulating feed valves
