Regio Midi – Pre-programmed room controllers with communication

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