How does a DCV system work?

The fan unit is installed in the attic/ utility or plant room. A separate duct is installed from the fan unit to the wet rooms such as the Kitchen, Utility, Bathrooms & WCs. Sensors, fitted inline in the duct, or in the room, depending on the brand used, measure air quality in each area.Based on these readings humid or stale air is extracted from the wet areas and fresh air is drawn into to the house through wall or window vents strategically positioned in each habitable area such as bedrooms, living rooms etc.
