In case of an emergency shutdown of a TwinFresh Expert RA/M1 unit in the network the defective ventilation unit is marked with the
blinking Alarm indicator. All the connected TwinFresh Expert RA/M1 ventilation units are also stopped.

In case of an emergency shutdown of the TwinFresh Expert Duo RA1 unit, 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
