OPERATION MODES
Vento Expert Vento Expert Duo
Ventilation: the ventilator runs either in extract or supply mode
at a set speed.
In this mode one group of the ventilators run in the supply mode
and the other in the extract mode, depending on position of the
DIP switch No. 3 (refer to page 13).
Boost: the ventilator goes to the maximum speed with the same
operation mode.
Regeneration: the ventilator runs in two cycles, 70 seconds each,
with heat and humidity regeneration.
Cycle I. Warm stale air is extracted from the room and flows
through the ceramic regenerator, which gradually absorbs heat
and humidity. 70 seconds after the ceramic regenerator starts to
get warm, the ventilator goes to the supply mode.
Cycle II. Fresh cold intake air from outside flows through the
ceramic regenerator, absorbs accumulated moisture and is
heated up to the room temperature by heat accumulated in the
regenerator. In 70 seconds after the regenerator cools down, the
ventilator goes again to the extract mode and the cycle starts
from the beginning. In this mode in case of installation of two
ventilators they operate with opposite rotation directions. While
one ventilator supplies air, the other one extracts air.
Air supply: the ventilator operates in the supply mode irrespective
of position of the DIP switch No. 3 (refer to page 13).
Ventilation: one fan runs in the air extract mode and the other fan
runs in the air supply mode at set speed. The fans do not change
the rotation direction.
Boost: in case of a sensor activation the ventilator follows one of
two functioning algorithms to be set during setup of the ventilator
with the DIP switch. For details, refer to the page 13.
DIP switch is set to OFF: the ventilator runs in the extract mode on
the third speed (both fans run in the extract mode).
DIP switch is set to ON: the ventilator goes to the maximum speed
in the same operation mode.
Regeneration: one fan runs in the extract mode and the other
one in the supply mode. Each 70 seconds the fans change the
rotation direction.

ventilator blinks and glows on other stopped connected ventilators. All the ventilators of the Vento Expert Duo
series in the network continue to run.
In case of an emergency shutdown of the Vento Expert Duo ventilator in the network the defective ventilator
does not influence the operation of other connected ventilators in the network.
In case of communication loss of the Master unit with the router longer than 20 seconds the Master unit goes
to the Standby mode (blinking Alarm indicator) and the Slave units will communicate communication loss with
the Master unit (refer description of the Master indicator). After resumption of the connection the Slave units
automatically get synchronised with the Master unit.
Master
Permanent glowing of the indicator indicates the Master unit.
Blinking of the indicator indicates the Slave unit and no connection with the Master unit.
No glowing of the indicator means that this ventilator is a Slave unit and it is connected to the Master unit.
Synchronous blinking of all the indicators on the casing of the ventilator indicates activated Setup Mode.

WIRELESS CONNECTION OF SEVERAL VENTILATORS
The ventilator has two operation modes.
Master unit mode. The ventilator acts as a Master unit. The Slave units and the mobile devices are connected to the Master unit via the
Wi-Fi connection. The Master unit is controlled via the mobile application, remote control or the sensor buttons on the ventilator casing.
The control signal is automatically transmitted to all the Slave units in the network. In this mode the ventilator receives signals from the
sensors (humidity sensor, external digital sensor, external 0-10 V analogue sensor) and goes to a respective operation mode.
Slave unit mode. The unit acts as a Slave unit in the network. The ventilator responds to the control signals from the Master unit only.
Any other signals from other controls are ignored. In this mode the Vento Expert ventilators ignore signals from the sensors. In case of
communication loss with the Master unit longer than 20 seconds the ventilator goes to the Standby mode.
Sensor-actuated operation. The Vento Expert ventilators respond to the signal from the sensors in the Master mode only.
The Vento Expert Duo ventilators respond to the signal from the sensors in any mode (Master or Slave).
In case of actuation of any sensors for Vento Expert, all the connected Vento Expert ventilators go to the maximum speed. The
Vento Expert Duo ventilators continue to run with the same speed.
In case of actuation of any sensors for Vento Expert Duo only the affected ventilator goes to the maximum speed according to the
humidity control scenario. The rest of the ventilators continue to run with the same speed.
WIFI PARAMETER SETUP
Setup of the Wi-Fi parameters is only possible on Master units. To set up ventilator Wi-Fi parameters via the
mobile app go to Menu - Connection - WI-FI setup.
