Room products
Bacnet Room Controller Units

  • Power modules equipped with output contacts for controlling:
    • different types of ON/OFF load (lighting, roller shutters, contactors, motors, etc.)
    • a DALI dimming output for 64 ballasts max or 16 Dali groups.
  • Loads are managed by the controls to which they are linked: either by BUS SCS controls, or by wired connection input terminals (switches, push-buttons, volt-free contacts)
  • 16 inputs – 16 outputs
  • 12 DIN modules 17.5 mm


3 power options:

  • One PSU (BT-346020) can be used to power the RCU and power the SCS bus at the same time. However as you can see in the technical datasheet this is only for very small rooms (max 100mA) So calculate the real power consumption for your hotelroom
  • The RCU can be powered over POE, the SCS bus (if used) needs to be powered with an external PSU  
  • Two PSU: external RCU PSU ( BT-346020) and individual SCS bus SCS, This has the advantage that the room keeps on being functional also when the network switches are going into maintenance for example.

A full hospitality room management system

The GRMS (Guest Room Management System) is the automation system of the hotel room. It manages information sent by the commands, allowing to operate many functions:

  • Light management (ON/OFF or dimmer)
  • Openings (curtains, rolling shutters and so on)
  • HVAC system
  • Launch ambiance and comfort scenes
  • Manage services as “Do Not Disturb” (DND) or “Make Up Room” (MUR)
  • Presence/absence of the guest in the room
  • Communication with third-party systems as supervisors, access controls, PMS, Smartphones/tablets, TV and so on

The BACnet solution allows the system to be interoperable with most PMS (Property Management System) and BMS (Building Management System) on the market
