ISR OZW/IKS characteristics

When used in combination with the BRÖTJE data portal, ISR OZW allows you to conveniently access your systems remotely via the internet. This offers heating engineers a continuous overview of their system inventory and the option to perform diagnostic and optimisation procedures remotely. In the case of maintenance and fault events, the plant operator and/or heating engineer will be informed directly by email, affording them the opportunity to respond immediately.
