Function
The iV-Smart
+
ventilation system is used to provide ventilation for living rooms and bedrooms.
An integrated thermal accumulator in combination with the reversible fan Xenion and the
JXLGLQJYDQHVHQVXUHVRSWLPXPKHDWUHFRYHU\ZLWKPD[LPXPDLUÀRZVLQLWVFODVV
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
HQHUJ\IURPWKHURRPVDLUDVLWÀRZVWRWKHH[WHULRU
(extract air). After 70 seconds, each Xenion reversible
fan changes direction. When the reversible fan
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 iV-Smart
+
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.
Due to the Xenion reversible fan's high pressure built-up and active speed control (integrated

is automatically switched to extract air mode for 4 cycles. This allows the thermal accumulator
to heat up again and prevents cooling of the interior due to cold drafts. During this phase, the

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).
The ventilation unit is controlled via one of the inVENTer system controllers. Depending on the
controller, operating modes and functions may be selected.
