In the good old days (not so long ago really), a chiller plant operator would go to the plantroom, open up a big log book and enter the parameters of the chiller plant. The readings would typically be from analog pressure gauges and temperature gauges (many of which would be showing readings that were just about close to the real values). Once entered into the log book, that was the end of the data recording till the next hourly reading. What happened in between the readings to the chiller was left to the compressor and the evaporator to handle.
