2.2
Function
The iV-Compact ventilation system is used to provide ventilation for living rooms and bedrooms.
An integrated thermal accumulator in combination with the Xenion reversible fan and the
guiding vanes ensures optimum heat recovery with maximum air flow.
The ventilation unit operates on the principle of heat re-
covery by changing the direction of the fan. The integrated
thermal accumulator charges itself with heat energy from
the room's air as it flows to the exterior (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-Compact
ventilation units are required. These are operated in pairs in push-pull operation: One ventila-
tion 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
wind stabiliser) the air flow within the system is kept nearly constant. Thus, the air flow
sensitivity to pressure variation meets the requirements of class S3 according to EN 13141-8
(max. 30 % air flow deviation at ± 20 Pa).
In order to ensure the full functioning of the ventilation system throughout the entire year, an
additional, flexible temperature sensor is integrated into the Xenion reversible fan.
This measures the temperature of the air flow. If the temperature falls below +5°C, the
reversible fan 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 mode that has been set on the controller is ineffective. Subsequently, the controller
switches the ventilation nit back to the originally selected mode.
A multi-use dust filter of filter class G4 is integrated discreet and easy of access into the inner
cover. It filters off reliably dusts as well as allergenic particles (such as pollen) from the ambient
air before it can enter living spaces. Dust filters are season independent. For special require
-
ments pollen and activated carbon filters are available as an option.
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.

Control elements
sMove controller
The controllers from the sMove product range are electronic control units
for controlling the iV-Compact ventilation units.
They are characterised by their timeless and slim design and a simple
touch-based operating concept.
The sMove controller is available in the s4 and s8 versions:
s4 is used to control up to four iV-Compact ventilation units.
s8 is used to control up to eight iV-Compact ventilation units.
Both versions are available in a flat and standard version: In contrast to
the flat version, in addition to pause mode, the standard version
provides the option to switch off the ventilation unit completely.
The connected ventilation units can be controlled in the following modes:
• Heat recovery
• Pause function
•
Continuous Ventilation • Off (only sMove standard version)
MZ-Home controller
The MZ-Home controller is an electronic control unit for controlling up to
16 iV-Compact ventilation units.
It is characterised by Clust-Air technology (multizone control),
simple installation, touch-based operation and its versatility.
The MZ-Home controller consists of a control unit and at least one (op-
tional up to four) Clust-Air module(s). Each Clust-Air module can control
up to four iV-Compact ventilation units in different zones within the ac
-
commodation unit. This allows the MZ-Home controller to provide varied
ventilation for up to four different areas (zones) within the accommodation
unit. For each zone, the operating mode and output level can be set manually or via a 7-day
timer.
The connected ventilation devices can be controlled in the following modes:
•
Heat recovery
• Dehumidification
•
Continuous Ventilation • Off / Pause function
The sMove and MZ-Home controllers can be expanded with additional sensors.
An external interface allows the connection of a potential-free switching contact or integration
into an existing home automation system via an analogue input.
For detailed information see the separate operating instructions of the controller.
