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 12).
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 12).
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 12.
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.
