What controls the ColdLogik Rear Door Coolers and how does it work?

The RDC’s are controlled by the ColdLogik Management System (CMS). The CMS adaptive intelligence is designed to control the whole room environment.  

The CMS continuously reads temperature from three zones, before the coil, after the coil, and an external room temperature sensor. The CMS uses the temperature information to control the volume of fluid provided by the valve, and the overall speed of the fans in the cooler.  Should the equipment inside the rack on occasion produce more heat, the CMS will react, and increase fan speed / fluid volume to achieve the air off temperature required. In the event of additional temperature changes required, the CMS can demand a change in supply water temperature from mechanical cooling.
