Ventilation device iV-Smart+
The iV-Smart+ ventilation devices are used to provide ventilation for living rooms and bedrooms.
An integrated ceramic thermal accumulator ensures optimum heat recovery.
The iV-Smart+ ventilation device is a ventilation device with simple airflow and works according to
the principle of heat recovery by changing the direction of the fan.
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 tem-
perature 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 automat

ically 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 regard

Optional pollen and activated carbon filters are available for special requirements.
