The slim and minimalist transmitter Regio RTX combines clarity, versatility, and seamless integration in one device. The LED matrix display with scrolling text is easy to read from a distance, simple to clean, and includes a traffic light for CO₂ levels as well as the possibility to display a custom text over communication. With built-in sensors for temperature, humidity, CO₂, VOC, and motion (PIR), it delivers complete indoor monitoring in a single unit. Flexible communication via BACnet, Modbus, or EXOline (in communication models) ensures smooth BMS integration. Built to complement modern architecture, the transmitter’s minimalist, slim design makes it an ideal choice for design-sensitive spaces. Installation is further simplified with an optional back plate with removable terminals, enabling setup in unclean environments and easy future servicing without exposing the electronics. Available with a countdown timer (RTX-T-CDE), providing control functions for ventilation or auxiliary equipment as well as with various sensor combinations with- or without display. Setup is quick with wireless configuration through the Regin:GO app or Application tool 2.
