Testing the implementation yourself

A manufacturer will often want to carry out tests himself, preferably during the development phase, in order to ascertain that he is heading in the right direction. He may possess a test specification which outlines the demands the product has to fulfil in order to comply with the Protocol Summary.

The manufacturer sends the test reports to the secretariat of the OpenTherm Association with a request to issue a licence for the products in which the certified version of the OpenTherm implementation is to be applied. The complete test and certification procedure can be found in the members part of the website.

Testing by an independent testing body

Another option to receive a license for an OpenTherm product, a prototype of the product has to be tested by Kiwa Nederland B.V. / Gastec, an independent testing body, using the new test tool.

Manufacturer’s self-certification

On the basis of a positive test report from either the new test tool or Kiwa Nederland B.V. / Gastec, the manufacturer himself sends the test report to the Secretariat and guarantees that the series of products which are manufactured on the basis of the tested prototype will be manufactured to the same technical standard as the prototype.

Obtaining a licence

Once all the preceding steps have been completed successfully, the association issues the requested licence to the manufacturer. This bestows upon him the right to market the stated product under the name and logo of OpenTherm. These agreements and procedures must guarantee that products marketed as OpenTherm are actually able to operate with other OpenTherm products.
