1. A temperature control system for controlling a temperature of a control target to a target temperature that changes with lapse of time, the system comprising:
a first adjustment apparatus that:
comprises a first tank that stores a first heat transfer medium,
adjusts a temperature of the first heat transfer medium to a first set temperature, and supplies the temperature-adjusted first heat transfer medium;
a temperature sensor that detects the temperature of the first heat transfer medium supplied from the first adjustment apparatus;
a first circulation circuit through which the first heat transfer medium flows from the first adjustment apparatus to a first flow-through path and returns to the first adjustment apparatus, wherein the first flow-through path supplies heat to the control target;
an adjustment section that adjusts an amount of the heat supplied from the first flow-through path to the control target;
a memory that stores a relation between the lapse of time and the target temperature; and
a controller that:
sets, at a first point in time and based on the stored relation, the first set temperature to a post-change target temperature, wherein the post-change target temperature is the target temperature after a first change timing at which the target temperature changes, and the first point in time precedes the first change timing by a predetermined time, and
causes the adjustment section to adjust the amount of heat and controls the temperature of the control target to a pre-change target temperature until the first change timing, wherein the pre-change target temperature is the target temperature before the first change timing.
