The Room Master Premium is a modular installation device (MDRC) in ProM design. It is intended for installation
in the distribution board on 35 mm mounting rails.

The assignment of the physical address as well as the parameter settings is carried out with ETS 2
from version V1.3a or higher.

The device is powered via the ABB i-bus® and does not require and additional auxiliary voltage supply.

The RM/S 2.1 is operational after connection of the bus voltage.


Hotels, hospitals, student residences, assisted living facilities, apartments and many more - the Room Master opens up new possibilities for properties in the residential and hotel sectors.

The Room Master was developed for all rooms of this type. It covers all the electrical installation requirements for this application and offers the following functions in a compact unit:
* Light switching
* Heating/air-conditioning control
* Shading (via blinds or curtains)
* Switching of socket outlets and consumers

In addition to these basic functions, further automation functions can be realised by combining the system with a presence detector. The communication of the devices via the KNX bus also enables central control functions and allows emergency
signals to be sent from the rooms to a central control station.

Connection to a hotel management system enables the rooms to be managed and prepared efficiently.

For instance, when a guest checks out, the room can automatically be set to stand-by operation.
