Holiday Inn Munich City Centre 
Part of the international Holiday Inn hotel chain, the Holiday Inn Munich City Centre is a modern 582-room hotel located at the heart of Munich. It is considered one of the city’s leading venues for business events, frequently hosting large-scale conferences, trade shows, and exhibitions.

HVAC System \ IDUs: Daikin VRV \ 600
After 18 years of operation, Holiday Inn Munich City Centre’s 53 Daikin VRV II outdoor units (ODUs), which belong to one of Germany’s largest Daikin hospitality HVAC setups, were reaching the end of their lifespan. Accordingly, the hotel’s management decided to replace them with the manufacturers’ more advanced VRV IV ODUs.
As only a part of the existing HVAC system was being replaced, it was critical to ensure that the new ODUs were properly connected to existing branch boxes and indoor units. However, it proved to be a complex undertaking, and the team at SG Cool GmbH, who was charged with the project, sought a solution to help ensure the upgraded system was set up properly. Moreover, they wanted to protect the costly new ODUs and minimize downtime.
To answer these needs, SG Cool GmbH partnered with us to deploy our management and predictive maintenance suite. After the HVAC system was connected to the cloud via CoolAutomation’s CloudBoxs, an installation working plan was created using performance data that was uploaded to the cloud and analyzed. Once all new ODUs were installed, metrics collected by the CloudBoxes were analyzed to confirm the HVAC system was operating optimally.
When the project was completed, CoolAutomation’s cloud-based platform allowed the hotel to carry out remote, continuous HVAC system management, monitoring, and diagnosis, with push notifications notifying the maintenance team of issues that can be diagnosed prior to a technician’s arrival on site. This facilitated early detection and repair of technical problems before guests complained and hotel operations were disrupted due to system downtime.
Lacking access to the HVAC system’s operational data, the new ODUs are installed “blind.” As a result, technicians face significant challenges in detecting potential performance issues that may arise, which can take considerable time and effort to resolve. When this process is completed, day-to-day HVAC system troubleshooting will take place as follows:
Through ongoing, remote access to comprehensive HVAC system data, the ODU replacement process becomes a fully controlled and transparent operation, significantly reducing the risk of unexpected issues occurring during and after installation while minimizing the time it takes to complete it. When this process is completed, day-to-day HVAC system troubleshooting will occur as follows:
