Correct behaviour is our top priority
In order for us to live up to our values, it is important to learn about possible misconduct and to put a stop to it. Employees, business partners, customers or other third parties have the opportunity to report irregular behaviour at any time via our whistleblowing system, Viessmann Integrity Line, and other reporting channels (e.g. via the supervisor or the Compliance Officer, by telephone, e-mail, letter, etc.).
