Adding the Smart automatic system package to your ventilation unit means you can make your home’s ventilation fully automated! The Smart automatic system measures the air’s relative humidity (RH) and carbon dioxide (CO2), and also detects odours and fumes (VOC). The ventilation flows are adjusted automatically, which guarantees a fresh and healthy indoor air for the whole house and everyone that is in it. It also saves energy and helps to prevent the problem of damp – smart and automatic.
