The ventilation unit can also be connected to a
building control technology system. Die RS 485
interface of the RLS 45 O or RLS 45 K control,
must be configured as a ModBus interface for this
purpose.
The ModBus connection is only possible with PP

When using the RS-485 interface as a ModBus
interface, no other components, such as
sensors, PPB 30 K room air controls or power
units can be connected to the interface.
