​
​Purpose: The graph provides a visual analysis of key operational parameters in the chiller system, particularly focusing on the evaporator and condenser circuits. It displays daily averaged values such as entering and leaving water temperatures, setpoints, compressor run hours, starts, and approach values. This helps technicians monitor trends over time and quickly identify deviations or unusual patterns, such as sudden temperature changes or increased compressor starts, which could signal faults, inefficiencies, or the need for maintenance.
