helpful when one looks at the technical data of frequently installed components closely, especially cost intensive components like controllers. The technical data includes information on minimum/maximum [...] implemented. As a result of the integration, there will be the possibility to access all operating data of the cooling unit in the future. Thus, the current temperature of the electrical enclosure can be [...] tunnel control system and, if necessary, can be replaced with such, without having to reinstall the data transfer. Another first in this development is attention paid to energy efficiency. An intelligent
