System overview: iV14-Zero ventilation device

The iV14-Zero ventilation device was developed as a sound insulation device. It is designed to ventilate living rooms and bedrooms in single- and multi- family houses, hotels and guest houses, rooms in public facilities and work rooms in office buildings.
It is suitable for installation in new buildings as well as for retrofitting in old buildings.
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 closeable inner cover with integrated air filter seals the iV14-Zero off from the interior space. Outside, a driving rain-proof cover conceals the components of the ventilation device.
The wall sleeve is equipped with a sound insulation lining made of Inventin. The insulated wall sleeve incorporates the ceramic thermal accumulator and inVENTron, two guiding vane elements and the Xenion 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 reversible fan effectively reduce the passage of sound.
The standard length of the wall sleeve is 495 mm. For thicker walls, a wall sleeve with a length of 745 mm can be ordered. Both versions can be shortened on site.
The ventilation device is controlled via one of the following inVENTer system controllers 1):

   2.2 Function
   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.

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.
Ventilation device iV14-Zero
The iV14-Zero ventilation devices are used to provide ventilation for living rooms and bedrooms.
An integrated ceramic thermal accumulator ensures optimum heat recovery.
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 iV14-Zero 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 rever- sible fan. The sound insulation lining effectively absorbs sound waves from outside and from the unit itself (sound transmission and inherent sound). The arrangement and design of the fanblades 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 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 S3 according to EN 13141-8 (max. 30 % 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 reversible fan. This measures the temperature of the air flow at the fan. If the temperature at the fan 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 unobtrusively and easily accessible 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.

  Inner boreholes (green arrow): Simplex.
  ► Drill the four holes with Ø 8 mm, min. 50 mm deep.

TIP: Do not apply the sealing tape until immediately before installing the base plate.
This prevents the sealing tape from swelling too much and makes installation easier.

► From the exterior wall side, attach the 9-mm sealing tape circumferentially flush with the guide on the base plate.
Do not seal the fixing holes!
► Insert the rawl plugs into the boreholes.
► Screw the base plate into the rawl plugs using 4 screws and washers.
TIP: When attaching the base plate to exterior walls with insulation or when using the wall installation block/Simplex wall installation system, use wallplugs for insulation for fixing purposes. These are not included in the scope of supply, they are available as an option.
NOTICE: If the joint between the base plate and the exterior wall is incorrectly sealed, the cover cannot be fitted.

• Seal only the upper joint between the base plate and the exterior wall.
  ► Seal the upper joint between the base plate and the exterior wall with a permanently elastic exterior sealant.
  ► Place the cover onto the base plate from the top.
  ► Slide the cover downwards as far as the stop.

4.6 Inserting the thermal accumulator insert
Inserting the sound insulation lining

NOTICE: The sound insulation lining is made from Inventin, a high- performing, patented material for use in decentralised ventilation devices. It absorbs sound waves from outside and from the device itself (sound transmission and inherent sound). Inventin is a sensitive material.

• To safeguard its sound-insulating function, handle the lining with care.

Requirements:

• The external termination is fitted.
  ► Remove the styrofoam disc from the wall sleeve.
  ► Place the front surfaces of the sound insulation lining against each other (standard) or around the inner ring of the ring insert (Corner | Nordic, dashed line).

• The coated side faces inwards.

• The abutting surfaces, where present, are located on a cut-out in the ring insert.
  ► Push the sound insulation lining with light tension into the wall sleeve until it stops (any ring insert present is aligned with the exterior wall).
  Position the abutting surfaces (red arrow) in the upper section of the wall sleeve (approx. 12 o’clock [upper fastening element]).

NOTICE
Do not store/stack the thermal accumulator insert outside the wall sleeve as doing so will damage the thermal accumulator’s ceramic.

• Insert the thermal accumulator immediately after removing it from the packaging.

Requirements:

• The external termination is fitted.

• The sound insulation lining is inserted.
  ► Insert the thermal accumulator from the interior into the lined wall sleeve.

• The handle points towards the interior.

• The connecting cables protrude into the interior.
  ► Carefully push the thermal accumulator towards the external termination until it stops.
  Take care not to damage the sound insulation lining made from Inventin.
  ► Insert the inVENTron from the interior into the wall sleeve so that you can reach the BUS plug connection.
  The narrow Slim guiding vane [16 mm] is aligned towards the interior.
  ⇒ The thermal accumulator insert has been inserted.

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:
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 position of the inner cover insert can be modified by clipping it in (e. g. top right cable connection).
The insert for the Flair Zero 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 insert 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 Flair Zero insert by unhooking it on all 4 sides.
► Rotate the insert by 90° in each case until the positions of the cable entry and connecting cable match.
Bottom left cable entry = position ex works
► Clip the Flair Zero insert into the base plate so that

• The position arrow on the base plate is pointing upwards, and
• The positions of the cable entry and connecting cable match.

⇒ The inner cover base plate is prepared.
Spirit level, pencil, hex key

Requirements:

• The thermal accumulator insert has been installed.
  ► Remove the thread locks from the fixing elements of the wall sleeve.
  ► Lay the connecting cable from behind through the cable entry of the prepared base plate.
  NOTICE: If the base plate of the inner cover is twisted, the inner cover panel cannot be fitted correctly!

• The position arrow on the inner cover base plate must always point upwards.
  ► Screw the base plate to the wall sleeve’s fixing elements using a hex key.
  The position arrow on the base plate points upwards.
  ⇒ The inner cover base plate is fitted.

4.8 Electrical connection of the reversible fan
The function of the iV14-Zero ventilation system requires the simultaneous operation of two iV14-Zero ventilation devices in push-pull mode. This section therefore describes the connection of a pair of devices, not a single device.
NOTICE
Incorrect electrical connection will damage the fan motor!

• Always connect the ventilation device to the mains supply via a controller.
• Ensure the correct sequence of the wire colours so that the fans start.

Stripping tool, screwdriver, blade, wire end ferrules (3 x 0.75 mm²)

Requirements:

• The reversible fan is inserted into the wall sleeve.

• The base plate or inner cover holding plate is fitted.
  ► Shorten the controller connecting cable, 3-wire, to your determined wall thickness minus 200 mm.
  ► Remove the cable sheath from the controller connecting cable.
  NOTICE: Using the wrong wire end ferrules to connect the cables in the plugin connector will lead to a short circuit in the fan BUS!

• Use wire ferrules with collars to connect the wire strands.
  ► Press wire end ferrules onto the cables, cable cross-section 0.75 mm².
  ► Loosen the plug connections on the reversible fans of the two ventilation devices.
  ► Align the plug connectors on the ventilation devices so that the clamping screws on both are facing in the same direction (e.g. upwards).

In paired operation, one reversible fan starts in extract air mode, the other in supply air mode. This start direction is determined by the different connection sequence of the three fan BUS cables in the plug-in connector.

► Secure the three fan BUS cables (controller connecting cables) in the plug- in connector:
Pair one with starting direction with exhaust air and the other with starting direction supply air
Exhaust air mode:

• (White) cable DIR1 (III) in the left pole.
• (Green) cable VOUT+ (IV) in the middle pole.
• (Brown) cable DIR2 (V) in the right pole.

Supply air mode:

• (Brown) cable DIR2 (V) in the left pole.
• (Green) cable VOUT+ (IV) in the middle pole.
• (White) cable DIR1 (III) in the right pole.

► Reconnect the connected plug-in connector to the plug-in connector on the reversible fan.

• The clamping screws of the plug connection are directed to the same side.
• The connections of the white and brown cable are swapped.
