The existing Siemens HVAC Control System required replacement.

We researched a solution that would control the HVAC Systems, and the reporting for the monitoring of Temperature / Humidity & Pressure to meet 21 CFR Part 11.

The decision was made to separate the HVAC Control from the monitoring. In doing so we reduced the connection between the Facility Management System, and the Validated System.
