let air flow through the ventilator. After the unit shutdown the shutters close within 2 minutes.
TwinFresh Expert
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 the position
of the DIP switch No. 3 (refer to section "Positioning of the DIP
switch").
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 section "Positioning of
the DIP switch")..

The shutters are open
TwinFresh Expert Duo
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 sensor activation, the ventilator follows one
of two functioning algorithms to be set during setup of the
ventilator with the DIP switch (refer to section "Positioning of the
DIP switch").
The DIP switch is set to OFF: the ventilator runs in the extract mode
on the third speed (both fans run in the extract mode).
The 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.
