Belimo sensors for a healthy and comfortable room climate

The new room units (sensors and room operating units) are the perfect addition to the existing product range. With the expansion of the product range for visible areas of the room, Belimo offers architects an aesthetic and timeless design. Installers appreciate quick assembly, system integrators easy commissioning with a smartphone. End customers enjoy not only a comfortable and healthy room climate but also the intuitive operation.

Innovation for peace of mind

Lean, timeless design.

Belimo room units impress with their aesthetic, timeless design and the shallow depth between 13 and 23 mm, depending on the sensor type. The room units can be seamlessly integrated into existing third-party controllers. They feature fast, tool-free assembly as well as high long-term measurement accuracy and short reaction times. The Belimo Assistant App enables simple commissioning of the active room sensors and their diagnosis with a smartphone. Thanks to Near Field Communication (NFC), parametrisation is possible even if the room sensor is not connected to the power supply.

Product range

Room operating units with ePaper touch display

The room operating units with display impress with their aesthetic and timeless design, which won the Red Dot Design Award. The ePaper touch display ensures the best legibility and simplest operation, without any lighting that may be disturbing at night.

  • Individually adjustable display for a wide range of applications 
  • CO2 traffic light function, which can be parameterised and deactivated via Belimo Assistant App
  • Fast installation thanks to spring-loaded terminal blocks and snap-on cover
  • Simple parameterisation and diagnosis via Belimo Assistant app

Room operating units with virtual display

The room operating units without display are ideal for rooms accessible to the public. The intuitive Belimo Display App enables setpoint adjustment on site without the need for a display on the room unit. Access can optionally be restricted by a four-digit code. The code remains stored on the mobile phone after it has been entered. This ensures simple, convenient and yet secure access without having to re-enter the code each time the Display App is used. The app is compatible with the latest generation of active room sensors and room operating units from Belimo.

Belimo Assistant App

The Belimo Assistant app offers full transparency of active Belimo room units, their settings and operating data at all times. In addition, it enables wireless, efficient commissioning, operational checks and diagnostics for the latest generation of room sensors. It is easy and ready to use at any time.

  • Set and display device-specific operating data and parameters
  • NFC data transmission with deenergised room units or during operation
  • Diagnosis page: device-specific state information
  • Transmit operating and setting data directly from the device via email, WhatsApp, SMS etc.
