New fresh air inlet:
This spigot is to connect the supply duct of fresh air from outside.
Install the fresh air intake (wall or roof) a sufficient distance from any area of
high pollution (trees, exhaust fumes, road, etc).
This duct must be sealed and insulated to prevent condensation on
the outside and inside.
Supply fresh air into the building:
Connected to the air intake duct in the property.
To avoid thermal losses, it is recommended to use insulated ducts for the
warmed air.
Extract air from the building:
Connected to the extract duct from the property.
To avoid thermal losses and optimise the performance of the installation, it is
recommended to use insulated ducts for the warm air.
By-pass:
Having avoided the heat exchanger, the 100% by-pass system of the IDEO
allows the introduction of cooler fresh air in the night without it being warmed
by the warm air accumulated in the house during the day.
Discharge of extract air
Connected to the discharge duct to the outside.
This duct must be well sealed and thermally insulated to avoid
condensation both on the inside and outside.
