Line Graph Comparison of Water Use versus Compressor Operation

This graph compares water flows from the high fountain versus condenser fin temperature on the same fountain (as a surrogate for compressor operation) for a continuous 2-day period (roughly noon Thursday through noon Saturday). The base temperature measurement is of ambient air temperature; when the fountain is used, however, the temperature of the spigot sensor is affected by the colder water and when the compressor operates the temperature of the condensor sensor is affected.

Question: Is there a correlation between water consumption (use) and compressor operation; if not, what is happening; are diurnal use patterns apparent in these data; could condenser temperature (not as obvious or intrusive a measurement as a sensor on the spigot) reasonably be used to estimate water use?

Comment: The elevated condenser "base" temperature that accompanies intensive use is intriguing.
