VENTILATOR CONTROL WITH THE BUTTONS ON THE INDOOR UNIT
The speed selection sequence is as follows: I-II-III-Standby. All the units integrated in a network run with the speed
set with the Master unit.
I: permanent glowing of the indicator indicates operation of the unit with the first speed. Blinking of the indicator
indicates activation of the
Night mode
timer.
I and II: permanent glowing of the indicators I and II indicates running of the ventilator at the speed II.
I, II and III: permanent glowing of the indicators I, II and III indicates running of the ventilator at the speed III.
Synchronous blinking of the indicators I, II and III indicates activation of the timer in the
Party mode
or the turn-
off delay timer in the Boost mode in case of actuation of the connected external sensors or integrated humidity
sensor.
Alternate blinking of the indicators I, II and III indicates running of the ventilator at the speed set with the mobile
application using the slider selector for manual speed setting or activation of the scheduler.
Regeneration mode
TwinFresh Expert
Rotation direction of the fan changes once in 70 seconds. Heat regeneration is accomplished in the Regeneration
mode. To enable operation of the ventilators in opposite directions change the position of the DIP switch No. 3.
TwinFresh Expert Duo
Rotation direction of the fans change once in 70 seconds. Heat regeneration is accomplished in the Regeneration
mode.
Ventilation mode
TwinFresh Expert
The ventilator runs in the extract or in the supply mode at the set speed. The fan rotation direction depends on
the position of the DIP switch 3.
TwinFresh Expert Duo
One fan runs in the air extract mode and the other fan runs in the air supply mode at a set speed. The fans do not
change the rotation direction.
No glowing of the indicators
“Regeneration”
and
“Ventilation”
indicates forced activation of the supply ventilation mode of the
ventilator. This mode may be activated via the mobile application only.
Filter
The filter clogging indicator starts blinking 90 days after installation of the cartridge. In this case, clean or replace
the filters (see the “Technical maintenance” section).
After replacement of the filters reset the filter timer using the mobile application or press and hold the
button on the indoor unit of the Master unit for 5 seconds, until a signal beeps.
Alarm
Alarm indicator. In case of failure, the
Alarm
indicator on the indoor unit glows or blinks.
Reasons of alarm blinking:
•
Battery charge is below the allowable limit.
•
No connection between the
Master
unit and the router.
•
Alarm shutdown of a ventilator.
If several interconnected ventilators are running in the same network, in case of alarm shutdown of one
TwinFresh Expert ventilator, all the other ventilators of this series also stop. The alarm indicator on the defective
ventilator blinks and glows on other stopped connected ventilators. All the ventilators of the TwinFresh Expert Duo
series in the network continue to run.
In case of emergency shutdown of the TwinFresh Expert Duo ventilator, 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 (see the 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
.
