Refrigeration control systems are continued to be developed to provide a high degree of operating accuracy and enhanced abilities to interface remotely.  Control systems today allow operating engineers to closely monitor and to set up operating parameters in the control system to not only monitor but to insure operating efficiency of the system is optimized.  Control system also possesses the ability to monitor the systems safety systems and to notify duty personnel of any problems and in those situations where the problems are life safety issues; the local authorities may be notified simultaneously.
