ModBus connection

The ventilation unit can also be connected to a building control technology. 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 45 or PPB 30 O single-type systems.

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

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.
