An Explanation of OpenTherm and How it Can be Integrated With KNX

OpenTherm is a non-manufacturer dependent system of communication between heating appliances and room thermostats. It consists of a communication protocol and an interface specification. OpenTherm is a futuristic technology combining simple installation procedure with high functionality and future expansion possibilities.

The OpenTherm Gateway from Theben allows the boiler to form an integral part of the KNX installation with the output from the boiler being adjusted to match the actual demand from the building.

Some of the features are:

  • Customised flow control
  • Weather compensation flow control
  • Control of domestic hot water
  • Energy optimisation of domestic hot water with solar support
  • Legionella protection program
  • Screed drying program

Please check with the manufacturer of the boiler for compatibility with OpenTherm.
