ModBus connection

The ventilation system can also be integrated into the building control technology. Your specialist installer can configure the RS 485 interface of the RLS 45 O or RLS 45 K control as a ModBus interface for this purpose.

The interface is set in service mode or using the commissioning software.

If the RS 485 interface is configured as a Modbus interface, no further components (PPB 30 K, sensors, power units, room air controls etc.) can be connected at this interface.
