Modbus controllers THERMASREG® MBR 100, MBR 200, and MBR 300 are communicative controllers and are used for monitoring, transmitting, and controlling the room temperature in heating and cooling systems. These devices are equipped with a large well-readable display and are set by single-knob operation (press-turn-press). They can either be operated stand-alone or in connection with a superior control device (SPS ⁄ DDC or Soft SPS), a building management system (RcWare Vision), a monitoring, control and data acquisition system, or a MBRWEB (a web browser interface), via the existing RS485 interface. Three device variants with differing features are available.
