PROBLEM TO BE SOLVED: To provide a temperature controller for a refrigeration showcase capable of carrying out energy saving during thermo cycle operation without lowering a load temperature to zero degrees or lower. SOLUTION: The temperature controller for the refrigeration showcase controls a temperature of an interior housing a load by repeating thermo-on and thermo-off. During pulldown operation, control is carried out by a first differential temperature DF1 such that the load temperature does not become zero degrees or lower, and then it is shifted to control of a second differential temperature DF2.
