VENTO Eco / VENTO Eco2
Internal ventilation grille with a decorative panel
Equipped with manually actuated louvre shutters.
Sound-absorbing material
Serves for sound attenuation of outdoor noise.
Cartridge
Generates air flow, provides energy
recovery and air cleaning.
Air duct
Plastic air duct.
External grille/outer hood
Protects the unit from ingress
of water and foreign objects.
The outer hood is not included in delivery.
Filter
Cleans the air flowing through
the ventilator of dust and for-
eign objects.
Prevents contamination of the
regenerator.
Fan
Generates air flow.
Regenerator
Provides extract air energy re-
generation for warming up of
supply air flow.
The unit consists of a protecting internal grille with a decorative panel, a cartridge, an air duct with a sound absorbing material layer and
a protecting external ventilation grille or a hood.
The cartridge is the basic functioning part of the unit.
The cartridge consists of a fan, a regenerator and two filters that ensure rough air filtration and prevent ingress of dust and foreign
objects into the regenerator and the fan.
The internal grille is equipped with manually actuated shutters to close the air duct during the unit standstill.
The external protective grille on the outer wall prevents ingress of water and foreign objects into the unit.
Cartridge is a block consisting of removable
filters and a solid fan-regenerator unit.
The filters are easy removable for technical
maintenance.

VENTO Eco / VENTO Eco2
UNIT OPERATION MODES
The unit has two ventilation modes:
Ventilation. The unit operates in permanent supply or extract mode at set speed. In case of two units operating in this mode one unit
operates in supply and the other one in extract mode.
Regeneration. The unit operates in reversible mode with heat and humidity regeneration in two cycles, 70 seconds each.
Cycle I.
As warm stale extract air flows through the ceramic regenerator, it heats up and moisturizes the regenerator and transfers up to 97 %
of heat energy.
In 70 seconds as the ceramic regenerator gets warmed the unit is switched to supply mode.
Cycle II.
Fresh intake air from outside flows through the ceramic regenerator, absorbs accumulated moisture and is heated up to the room
temperature.
In 70 seconds as the ceramic regenerator gets cooled down, the unit is switched to air extract mode and the cycle is renewed.
In this operation mode, in case if two units are installed each of them operates two cycles in opposite phases.
While one unit operates in air supply mode the other one operates in air extract mode.

WALL-MOUNTED CONTROL PANEL INSTALLATION AND CONNECTION
INSTALLATION AND CONNECTION OF THE CONTROL PANEL SHALL ONLY BE
PERFORMED BY A PROFESSIONAL ELECTRICIAN.
MAKE SURE THAT THE CONTROL PANEL IS NOT DAMAGED. DO NOT USE A DAMAGED
CONTROL PANEL!
DO NOT INSTALL THE CONTROL PANEL ON AN UNEVEN SURFACE!
WHILE TIGHTENING THE SCREWS, DO NOT APPLY EXCESSIVE FORCE TO PREVENT THE
CONTROL PANEL CASING DEFORMATION.
1. Prepare a hole in the wall and route all the wires to
the installation place. Insert the supplied mounting box
for flush wall mounting. The mounting box is included
in delivery.
 94 mm (3 /") 34 mm (1 /")

2. Use a screwdriver to carefully undo the clips on the
backside of the control panel and remove the back
cover.
3. Screw the backside of the casing to the mounting
box through the fastening holes. Fastening screws
for mounting of the control panel are included in the
control panel delivery set. Then connect the cable
to the control panel in compliance with the external
wiring diagram.
4. Install the control panel display and press it to fix.

UNIT MOUNTING
READ THE USER’S MANUAL PRIOR TO MOUNTING THE UNIT.
WARNING!
DO NOT BLOCK THE AIR DUCT OF THE INSTALLED UNIT WITH DUST ACCUMULATING
MATERIALS, SUCH AS CURTAINS, CLOTH SHUTTERS, ETC. AS IT PREVENTS AIR
CIRCULATION IN THE ROOM.
1. Prepare holes for the air ducts.
Prepare one or two round core holes in the outer wall, depending on the unit equipment.
For efficient operation of the ventilation system it is recommended to install the units as far apart from one another as possible.
While preparing core holes it is recommended to make preparations for layout of the power cable and other required cables.
The core hole size and minimum distance to a mounting surface, for example, a wall, ceiling or a window as well as the minimum
distance between the units are shown below.

Measure the wall thickness B.
The air duct length is calculated as L = B + A, where A
means an air duct segment that protrudes in the outer
wall to enable installation of the external grille or the outer
ventilation hood. For details, see the table below.

Cut the air duct to the length L, without consideration to the
cable groove.
Insert the air duct into a prepared hole in the wall.
The cable grooves must be located on inner wall side.
The air duct end on the indoor side must be flush with the
inner wall side.

3. Install the sound-absorbing layer in the air duct. Prior to installation adjust its length with respect to the dimensions of the cartridge,
external grille or the outer ventilation hood as well as the internal square or round grille.
This example shows adjustment of the sound-absorbing layer length calculated from the ange width of the square inner grille.
Insert the cartridge during adjustment in the air duct.
The distance L from the edge of the air duct is equal to the
width of the flange of the inner grille.
For a square grille L = 40 mm (1 9/16") for a round one
L = 20 mm (13/16")
During adjustment of the insulation layer length cover the air
duct and the cartridge with the internal grille.
Roll the sound-absorbing layer to match the air duct diameter
with the protecting paper layer outside and insert the roll in
the air duct against stop.
Do not remove the paper layer!
