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.

network of the connected ventilation units. Its blinking indicates shutdown of a specific ventilation unit in the network.
In case of an emergency shutdown of a TwinFresh Expert RW1 unit in the network the defective ventilation unit is marked with the blinking
Alarm indicator. All the connected TwinFresh Expert RW1 ventilation units are also stopped. All the connected TwinFresh Expert Duo RW1
ventilation units continue operating. In case of an emergency shutdown of a TwinFresh Expert Duo RW1 unit in the network the defective
ventilation unit is marked with the blinking Alarm indicator. The defective ventilation unit shuts down and the other connected ventilation
units continue their operation.

Master unit indicator
Permanent glowing of the indicator shows the leading unit in the network (Master unit).
Indicator blinking indicates the driven unit (Slave unit) and no connection to the Master unit.
No glowing of the lamp indicator means that this ventilation unit is a Slave ventilation unit and it is connected to a Master unit.
Synchronous blinking of all the lamp indicators on the casing of the ventilation unit means active setup mode performed by a PC.
In this case the fan shuts down.
