RXC controllers – the integrated and open total controller range for individual rooms

RXC controller

RXC controller is a range of individual room controllers for HVAC systems and includes integrated controllers for lighting and blinds. The RXC controller devices communicate via a standard bus system (LonWorks® technology). The room controllers and room units in the RXC controller range control and monitor comfort conditions in rooms and self-contained zones. These functions are finely tuned to the specific requirements of the area concerned (room or zone).

Key features

  • Energy savings of up to 14% ensured by eu.bac-certified products with high control accuracy

  • Applications for heating, cooling, ventilation, air conditioning, lights and blinds

  • Open communication based on LonWorks technology

  • Suited for use in connection with third-party products

  • Applications are downloadable

  • Easy engineering with software tools, such as RXT10 or standard LNS tools

RXB controller

The RXB controller range of products performs all HVAC functions while – for the control of lights and blinds – various devices are available from different manufacturers. This third-party equipment can be easily combined with RXB controller thanks to the clarity of the KNX specification, the certification procedure, and the use of ETS tool software.

Key features

  • Energy savings of up to 14% ensured by eu.bac-certified products with high control accuracy

  • Economic communication solution

  • Applications for heating, cooling, ventilation and air conditioning / Efficient integration into Synco™ and DESIGO

  • Open communication based on KNX® and applications certified by the Konnex Association

  • Suited for use in connection with third-party products

  • Reduced training effort thanks to Preloaded Application Set

  • Easy engineering with the ACS commissioning tool or ETS3 Professional and HandyTool

RXL controllers – the favourably priced HVAC controller range for individual rooms

RXL controller

RXL controller is an innovative range of room controllers and room units for cost-effective room management. Data communication is based on a proprietary DESIGO bus, which provides the transition to BACnet®. RXL controller thus fits into the overall expandable modular system, ensuring long-term cost-effectiveness. Commissioning and parameter setting of the RXL controllers are carried out with the software tool, or directly on the controller via the QAX34.3 room operating unit used as HandyTool. The parameters can be set via the room unit with no need for a network connection. These controllers also communicate with the Synco 700 controller.

Key features

  • Proprietary communication

  • Applications for heating, cooling, ventilation, and air conditioning

  • Economic integration into Synco and DESIGO

  • Reduced training effort thanks to preloaded application set

  • Easy engineering with ACS commissioning tool and HandyTool

RXA controllers – range for comfortable standalone individual room control

RXA controller

RXA controller is a range of non-communicating controllers. The available applications and room units are the same as those used with the other RX ranges.

Key features

  • Controllers in compact design with excellent control performance

  • Different operating modes (Comfort, Standby, Eco, Protection)

  • Support thermal or electrical actuators, and supply air temperature control

  • Applications for radiators and fan coils with heating, ventilation, or cooling

  • Master/slave function and central change of operating mode via timer

  • Reduced training effort thanks to preloaded application set and tool, which also reduce installation and configuration work (switches)
