The sys-tek team knows controls. We have worked on almost every conceivable control system manufactured, including PLC systems. Typically what we find are software bugs and calibration problems, which can be easily overlooked because systems will fix themselves by reconfiguring the distribution of energy. This is where optimization of control systems is critical. It is not only the sequence, but the components that can provide real energy savings and optimization. The key to energy optimization is remembering you cannot optimize what you cannot measure.
