Function
The iV14-Zero ventilation system is used to provide ventilation for living rooms and bedrooms.
The combination of inVENTron, and sound insulation coating made of Inventin ensures optimum

The ventilation unit operates on the principle of heat
recovery by changing the direction of the fan. The
integrated thermal accumulator charges itself with heat

(extract air). After 70 seconds, each Xenion reversible

changes direction, it releases the stored heat energy
into the incoming outside air (supply air).
For this principle to work correctly and to ensure the
room’s pressure stability the incoming air and extract
air volumes must match, i. e. two iV14-Zero ventilation units are required. These are operated in
pairs in push-pull operation: One ventilation unit works in supply air mode while the other works
in extract air mode at the same time.
iV14-Zero is characterised by its silent operation. The patented sound insulation concept is based
on a combination of the coating made of Inventin and the Xenion reversible fan. The sound
insulation coating absorbs acoustic waves from outside and the unit itself (sound passage and

A decentralised ventilation system is based on the free movement of air between individual
pairs of ventilation units. Therefore, internal doors must not have air-tight seals.
Ensure adequate air transfer measures: An air gap of about 10 mm below the door, unscrew the
hinges by 5 mm, use a ventilation grille or similar (cross ventilation).
