2 System Overview: iV-Office Ventilation Device

The iV-Office is a decentralised ventilation system with heat recovery, designed for increased air flow requirements. It is suitable for new and existing buildings, especially large living spaces and commercial premises like offices and surgeries. Installation is typically in the exterior wall.

The device consists of a wall sleeve with a mounted thermal accumulator insert. A lockable inner cover conceals the unit, and an integrated filter prevents pollen and dust ingress. An exterior driving rain-proof cover protects the components.

Sound insulation lining made of Inventin absorbs sound. The system includes a ceramic thermal accumulator, inVENTron, guiding vane elements, and the Xenion EFP reversible fan. Guiding vanes straighten airflow for efficient heat accumulator flow. The sound-absorbing lining and fan blade design reduce noise.

The standard wall sleeve length is 495 mm; a 745 mm version is available for thicker walls. Both can be shortened.

The device is controlled via inVENTer system controllers such as sMove or MZ-Home.

Components

• Inner cover including ISO Coarse 60% filter
• Thermal accumulator insert (thermal accumulator, inVENTron, sound insulation lining made of Inventin)
• Wall sleeve
• External termination (e.g., Flex Office weather protection hood)
• Optional: Pollen and activated carbon filter

2.2 Function

Decentralised Ventilation

Decentralised ventilation systems combine extract and supply air using free air movement between pairs of devices (cross-ventilation). Each device is in its own air duct.

The system operates on heat recovery by changing fan direction. The thermal accumulator stores heat from extract air (external flow) and releases it to supply air (internal flow) after approximately 70 seconds. For correct operation and room pressure stability, supply and extract air volumes must match, requiring at least two devices operating in a push-pull mode.

Operation is via inVENTer controllers, allowing individual setting of operating modes and air volumes. Key components include the ceramic thermal accumulator, reversible fan, guiding vanes, filters, inner cover, outer cover, and controller.

Ventilation Device iV-Office with Heat Recovery

The iV-Office provides ventilation for living and commercial spaces, ensuring maximum heat recovery with minimal noise and maximum airflow through its combination of inVENTron, thermal accumulator, and sound insulation lining. It operates quietly due to its patented sound insulation concept using Inventin lining and the Xenion EFP reversible fan.

The fan's speed control and integrated wind pressure stabiliser maintain near-constant airflow, even with pressure fluctuations (Class S2 according to EN 13141-8). A temperature sensor ensures year-round function; if the temperature drops below +5°C, the fan automatically switches to extract air mode for 4 cycles to reheat the accumulator and prevent cold supply air. The controller then resumes normal operation.

A standard washable ISO Coarse 60% dust filter is included, filtering dust and allergens. Optional pollen and activated carbon filters are available.

2.3 Control Elements

Operation is via an inVENTer system controller, offering different modes and functions.

Basic Controls (sMove)

Multi-zone Control (MZ-Home)

For detailed information, see the controller's installation and operating instructions.
