R-ION Sedona Room Controller



 R-ION Topologies

 Hotel Demo


R-ION series products are programmable room controllers ideal for managing a wide range of individual building products such as fan-coil units and VAV boxes.

Extremely flexible customization options are available thanks to configurable color touchscreen, full programmability, custom logo possibility and various styles and color options.

The unit has no on-board inputs & outputs, but is able to connect to a multitude of external IO, due to multiple communication ports and protocols. Integrated temperature sensor is standard on all versions. The unit can also be ordered in a temperature plus relative humidity sensing configuration.

In addition to basic fan-speed and temperature settings, lighting controls can easily be integrated, as well as custom application specific functions (e.g. Do Not Disturb / Make Up Room buttons for hotel rooms).

Frame Styles

Two frame styles are available. The original smaller frame (style 1) can be supplied in white or black.

The newer frame (style 2) presents a more contemporary look, with white or black acrylic glass bezel. Other inset options can be available on demand, including other colors and finishes (e.g. wood, metal, brass..)

R-ION controllers support various industry standard protocols simultaneously. The main supervisory system communication (Port 1) is serial RS485 or wireless IP depending on basic version:

  • WIFI versions support Sox protocol, BacNET IP (slave), ModbusTcp (master and/or slave)
  • Serial versions support BacNET MSTP (slave) and Modbus RTU in either master or slave configuration.

Optionally, one or more of the following auxiliary communication ports may be available:

  • Second RS485 port (Modbus & DMX drivers available)
  • Belimo MP-Bus port
  • DALI (Digital Addressable Lighting Interface) port


Two-piece interlocking design greatly simplifes installation on the wall-unit side, as the IO module can be located close to the terminal unit being controlled, with only comms wiring into the wall unit.

  • 3.5” resistive color touch-screen
  • Freely programmable
  • Fully customizable graphics
  • Powered by Sedona Framework
  • Integrated temperature sensor
  • Optional relative humidity sensor
  • WIFI option
  • Belimo MP-Bus option
  • Dali (Digital Addressable Lighting Interface) option
  • DMX driver available
  • Low profile, only 10.5 mm thick
  • Optional Input/output modules optimized for terminal units (e.g. Fan-coil, VAV...)

Surface-mount option

R-ION controllers are typically flush-mounted on a standard recessed wall-box, allowing a visible depth of only 10.5 mm. A surface mount back-box will also be available (end of 2016).


Developed by Tridium, Sedona is the industry's first, open source development framework that provides a complete software platform for developing, deploying, integrating, and managing pervasive device applications. It brings the power of programmable control and the Internet down to edge devices. Sedona distributes decision making control and manageability to any device and brings intelligence and connectivity to the network edge and back.
