Regio Midi are controllers with a built-in temperature sensor and an RS485 communication port. Some models are available with CO2 sensors. Controllers in different rooms and zones can be connected to a bus line enabling communication with a central SCADA system via RS485(EXOline, BACnet or Modbus).

RC-CD* and RC-C3D* are BTL listed.
