4.1 Room automation – Room controller unit
(RCU)
The room controller unit (RCU) is assigned the most important functions within the
integrated system. It communicates both with the connected peripheral devices in
the guest rooms as well as directly with the HRMS management station at the
reception desk.
All important room parameters can no longer be lost after system commissioning
and configuration and are autonomously stored in the controller. This guarantees
full functionality of all local room functions even without a network connection.
Two room control units are available for Hotel Solution:
• HRC3.1 – for expanded requirements (Advanced)
• HRC3.2 – for standard requirements (Standard)
