SYSTEM OVERVIEW: IV-OFFICE VENTILATION DEVICE

2 System overview: iV-Office ventilation device

The iV-Office is a decentralised ventilation system with heat recovery and is designed for increased air flow requirements (performance-plus device). The iV-Office is suitable for installation in new buildings as well as for retrofitting in older buildings and is particularly suitable for use in large living spaces and similar commercial premises (e. g. offices, doctors’ surgeries, lounges, etc.). Installation is generally carried out in the exterior wall.
The ventilation device consists of a wall sleeve in which the thermal accumulator insert is mounted. A lockable inner cover conceals the iV-Office discreetly from the interior. The filter integrated into the inner cover ensures that no pollen or dust from outside enters the interior. Outside, a driving rain-proof cover conceals the components of the ventilation device.
The sound insulation lining made of Inventin, a material specially developed to reduce noise, is inserted into the wall sleeve. The insulated wall sleeve incorporates the ceramic thermal accumulator and inVENTron, two guiding vane elements and the Xenion EFP reversible fan. The guiding vanes on both sides of the fan serve to straighten the air flow and ensure more efficient flow through the thermal accumulator. The sound-absorbing Inventin lining and the unique geometry of the Xenion EFP reversible fan effectively reduce the passage of sound.
The standard length of the wall sleeve is 495 mm. For thicker walls, a wall sleeve and insert with a length of 745 mm can be ordered as an alternative. Both versions can be shortened on site.
The ventilation device is controlled via one of the following inVENTer system controllers1): · sMove · MZ-Home

Components

· Inner cover incl. ISO Coarse 60 % filter · Thermal accumulator insert (thermal
accumulator, inVENTron and sound insulation lining made of Inventin)

· Wall sleeve · External termination2) · Pollen and activated carbon filter (optional) · Sound and wind protection accessories
(optional)

Models
The ventilation devices of the iV-Office product range differ in their external terminations. Additional inner covers are also available. This documentation only contains information on the standard version of the ventilation device. For information on the variants of the exterior and internal terminations, please refer to the separate installation instructions for the respective component:

SYSTEM OVERVIEW: IV-OFFICE VENTILATION DEVICE
2.2 Function Decentralised ventilation
Decentralised ventilation systems combine extract and supply air and are based on free air movement between individual pairs of ventilation devices (cross- ventilation). The cross-ventilation principle allows the air to circulate through the entire residential device and also sufficiently ventilate interior living spaces. Each ventilation device is mounted in its own air duct so as not to obstruct other ventilation processes.
70 s

The decentralised iV ventilation systems with heat recovery consist of ventilation devices arranged in pairs with simple air flow. They operate according to the principle of heat recovery by changing the direction of the fan. The integrated thermal accumulator is charged with the thermal energy of the room air as it flows externally (extract air). After 70 seconds, the reversing fan changes the direction of rotation each time. After the direction of rotation has changed, the heat accumulator releases the stored heat energy to the incoming fresh air (supply air).
For this principle to work correctly and to ensure pressure stability in the room, the supply air volume must always correspond to the extract air volume, i.e. at least two ventilation devices are required. These are operated in pairs in push-pull mode: another ventilation device is assigned to the ventilation device that delivers supply air and at the same time removes used extract air from the interior to the outside.
You operate the iV ventilation systems intuitively with the matching inVENTer controllers. Different operating modes or the air volume flows can be set individually.
The most important components of the iV system are the ceramic thermal accumulator, the reversing fan, air guiding vanes for straightening the air volume flow, filters for different hygienic requirements, a closable inner cover and an outer cover. A control device (controller) completes the system.

iV-Office ventilation device | Installation instructions

SYSTEM OVERVIEW: IV-OFFICE VENTILATION DEVICE
Ventilation device iV-Office with heat recovery
The iV-Office ventilation system is used to provide ventilation for living spaces and living space-like commercial premises. The combination of inVENTron, thermal accumulator and sound insulation lining ensures maximum heat recovery with minimum sound emissions and maximum air flow.
It is a ventilation device with simple airflow and works according to the principle of heat recovery by changing the direction of the fan.
The iV-Office features especially quiet operation. The patented sound insulation concept is based on the combination of the sound insulation lining made of Inventin with the Xenion EFP reversible fan. The sound insulation lining effectively absorbs sound waves from outside and from the device itself (sound transmission and inherent sound). The arrangement and design of the fan blades additionally reduces the sound transmission from outside.
Thanks to a high pressure build-up and the active speed control of the motor (integrated wind pressure stabiliser) in the Xenion EFP reversible fan, the air flow in the system is kept almost constant even in the event of weather- related pressure fluctuations. Thus, the sensitivity of the air flow to pressure fluctuations corresponds to class S2 according to EN 13141-8 (max. 20 % air flow deviation at ± 20 Pa). In order to ensure the full functioning of the ventilation device throughout the entire year, a temperature sensor is integrated into the Xenion EFP 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 supply air. During this phase, the operating mode that has been set on the controller is ineffective. Subsequently, the controller switches the ventilation device back to the originally selected mode.
As standard, a washable ISO Coarse 60 % class dust filter is integrated into the inner cover. This filters coarse dust and allergenic particles (such as coarse flower pollen) from the air before they can enter the interior. The dust filters can be used regardless of the season. Optional pollen and activated carbon filters are available for special requirements.

4.7 Installing the inner cover base plate

The assembly of any interior termination variants is not part of this documentation! It can be found in the separate installation instructions for the respective component.

Preparing for installation:

i

The correct installation of the inner cover requires that the installation position of the base plate (installation position arrow pointing upwards) is not changed.

To ensure that, even in the event of a different cable routing, correct connection of the reversible fan is possible, the orientation of the adapter can be modified (e. g. top right cable connection). The adapter for the Flair XL inner cover is pre-assembled at the factory so that the cable entry is located at the bottom left when it is being attached. If the cable is long enough, it can optionally be laid between the ring insert and the sound insulation lining to the cable entry.

Before installation, check whether any adjustment of the inner cover adapter needs to be made. If necessary, change the position of the cable entry so that it matches the conditions of the installation location:

Remove the base plate from the adapter by unhooking it on all 4 sides.

TIP: Once the base plate has been removed from the adapter, you can make the drill hole
i markings for attaching the inner cover to the interior wall.
