VENTILATOR OPERATION MODES
TwinFresh Expert RW1
TwinFresh Expert Duo RW1
Ventilation:
the ventilator runs either in air extraction or air supply
mode at a set speed.
In this mode some of the ventilators in the network run in air supply
mode and the other ones in air extraction mode, depending on
the direction set using the personal computer (see page 18).
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. In 70 seconds, as the ceramic regenerator gets
warmed, the ventilator is switched to air 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 ventilator is switched to air extraction
mode and the cycle is renewed. If two ventilators are installed,
they operate with opposite rotation directions in this mode. While
one ventilator supplies air, the other one extracts it.
Boost mode
is activated when the external relay sensor, the
external 0-10 V analogue sensor or the integrated humidity sensor
is triggered.
The ventilator operates at maximum speed without changing the
operation mode.
After all sensors return to normal state or upon elapse of the turn-
off delay timer countdown (from 0 up to 24 hours, factory setting
30 minutes) the ventilation unit reverts to the previous speed.
Supply mode
is activated only using the mobile application.
The ventilator operates in the supply mode irrespective of the air
flow direction set via the personal computer (see page 18).
One fan operates in the air
extraction mode
and the other fan
operates in the air supply mode at set speed. The fans do not
change their rotation direction.
Regeneration -
one of the ventilator fans operates in the air
extraction mode and the other one operates in the air supply
mode.
The fans change their rotation direction every 70 seconds.
Boost mode
is activated when the external relay sensor, the
external 0-10 V analogue sensor or the integrated humidity sensor
is triggered.
The ventilator operates at maximum speed and follows one of two
functioning algorithms to be set during setup of the ventilation
unit via a PC. For details, refer to page 18.
Humidity control scenario:
• Increase speed and switch to air extraction mode (both fans
operate at air extraction mode)
• Increase speed in current mode.
After all sensors return to normal state or upon elapse of the turn-
off delay timer countdown (from 0 up to 24 hours, factory setting
30 minutes) the ventilation unit reverts to the previous speed.
Supply mode
is activated only using the mobile application.
Both fans operate in air supply mode.
