Claim:
1. A thermal source instrument controlling device for controlling a plurality of thermal source instruments that produce cooling/heating water, the thermal source instrument controlling device comprising: a setting value calculating portion that calculates setting values for feed water temperatures for the cooling/heating water to be produced by the respective thermal source instruments; a change magnitude calculating portion that calculates change magnitudes for the feed water temperatures of the thermal source instruments based on instruction data for directing a change in temperature of the cooling/heating water to be supplied to a load instrument; and a feed water temperature setting portion that corrects, based on the change magnitudes for the feed water temperatures calculated by the change magnitude calculating portion, setting values for the feed water temperatures for the respective thermal source instruments, calculated by the setting value calculating portion, and sets the corrected values in the respective thermal source instruments, wherein the change magnitude calculating portion calculates change magnitudes for the feed water temperatures for the respective thermal source instruments based on temperature change magnitude information included in the instruction data, setting values for the feed water temperatures set for the respective thermal source instruments, flow rates of the cooling/heating water that flows out from the respective thermal source instruments, and weighting coefficients set for the individual thermal source instruments.
