OpenTherm interface for KNX: KNX-OT-Box

With the new KNX-OT-Box Theben is breaching the gap between two worlds: KNX and OpenTherm heaters can be linked via this universal interface. It can be used as the master for the OpenTherm heater in combination with a KNX individual room control.

A summary of the highlights of OpenTherm interface for KNX: 

  • OpenTherm and KNX
    The new interface from Theben links the KNX BUS with the OT BUS widely used with gas water heaters. As a master, the KNX-OT-Box enables the bidirectional exchange of data between the OpenTherm heater and the heat distribution via the KNX system for individual room control.
  • Simple to use via multi-functional display
    The VARIA 826 KNX multi-functional display  can be used to set and change settings for the boiler control. They are transmitted to the OpenTherm heater via the KNX-OT-Box.
  • Pilot room control
    The new interface now not only enables pilot room control but also maximises feed as required for all rooms.
  • Energy saving service water heating
    Heating domestic water with a solar power system helps save energy as the amount of sunshine expected according to weather forecasts can be taken into account when heating water. Beyond that, the energy-optimised legionella protection prevents unnecessary heating of the storage tank to the legionella protection temperature.
  • Screed drying program
    The Theben KNX-OT-Box can be easily and quickly set up using removable bus coupling units and the factory preset "screed drying program as per DIN EN 1264-4".
