This operational practice is intended to educate individuals working in broadband communications critical facilities on what cooling system set points are and how adjusting set points can impact cooling system operational efficiency. The objective is to provide engineers, technicians and contractors a basic understanding of those impacts so set point adjustments will not be done casually but instead be part of the overall goals to optimize the efficiency of the cooling and heating systems without risk of creating conditions which could cause information and communications technology (ICT) equipment to fail. There are significant implications with respect to the operational efficiency of the facility that can result from changing cooling system set points for the wrong reasons.
A better understanding of cooling system set points will enable people working in critical facilities to avoid actions that may prove detrimental to the facility operation.
