Why Distech Controls technology?

Since this is a high-rise office building in La Défense, the specifications include extensive requirements and there is a substantial investment involved. Our client felt they could safely opt for our tried and tested ECLYPSE solution – now in use for over 6 years – in full BACnet/IP BBC. This is a modular solution accessible to services at no extra cost, ensuring that the building will remain flexible and future-proof for the long term. As a result, our client has control over the tower’s technical management and will be free to install any type of connected service at a later time. What’s more, our solution delivers a robust cybersecurity protocol, a guarantee that further reassured our client. Last, but not least, we offer regular technical monitoring and continual local sales support.
