The CoolLogic Control System governs all top level events, timing and compressor staging, and allows operator interface for all levels of setting and retrieving data. The CoolLogic Control System provides leaving chilled and hot water liquid temperature control algorithms which maintain precise temperature control for cooling, heating, heat recovery and simultaneous heating and cooling applications. A compressor run time equalization sequence is given to ensure even distribution of compressor run time throughout the entire chiller bank. Chiller power consumption is minimized by indexing the most efficient stages of cooling, optimizing heat transfer surface.
