FEATURES

Arrangement of efficient energy-saving supply and exhaust single-room ventilation in flats, houses, cottages, social and commercial premises.Reducing heat losses caused by ventilation due to heat recovery.Humidity balance and regulated air exchange create individually controlled microclimate.Coordinated network based on several integrated single-room ventilation units with central control.

DESIGN


Easy maintenance. Indoor unit is opened by pressing the latches on both sides	One of the best regeneration efficiency on the market due to innovative hexagonal structure of the heat exchanger cells	Integrated automatic air shutters prevent air back drafting	The specially designed front panel can be closed manually to ensure 100 % air tightness and protect against wind impact

HEAT AND HUMIDITY REGENERATION

UNIT OPERATING LOGIC IN WINTER PERIOD

Warm stale air is extracted from the premise, flows through the ceramic regenerator and transfers its heat energy and moisture to it.As the ceramic regenerator gets warmed up, the unit switches to the supply mode.
Clean cold intake air flows through the regenerator and absorbs accumulated heat and humidity.When the ceramic regenerator is cooled down, the unit switches to the extract air mode.

CONTROL

Control of the unit operation mode is performed by means of sensor control panel located on the unit casing or a remote controller.

Vento Expert is equipped with a humidity sensor for indoor humidity control. If humidity increases above a set point, the unit boosts to the speed III.

Vento Expert either can operate as independent unit or can be connected with other units in a house and controlled with a master unit. In this case, only the master unit receives a signal from the remote control.

MOUNTING

The unit is designed for through-the-wall installation inside a prepared hole in an outer wall of the building.The best ventilation solution is pairwise installation of reverse phase connected units. Some units ensure supply of fresh air to the room and the other units extract air from the premise. This way the most efficient balanced ventilation is arranged.

In case of brand new construction, units are mounted in two stages:

Pre-installation at the stage of the indoor finishing and outer decorative wall finishing. It includes installation of an air duct, an outer ventilation hood and cable installation.
Final mounting before commissioning of a house. It includes installation of a regenerator with a fan and filters and mounting and wiring of an indoor unit with a controller and shutters.
