PROBLEM TO BE SOLVED: To provide a temperature controller for a refrigeration show case with the inexpensive manufacturing cost capable of controlling the rise of temperature of any article in a chamber due to defrosting. SOLUTION: In a temperature controller for a refrigeration show case for controlling temperature in a chamber by repeating thermo-on and thermo-off, temperature at an on-point A of the thermo-on is set to a predetermined temperature of zero degree or higher, and temperatures of off-points B1, B2, B3 at the off point B of the thermo-off are controlled by altering differentials DF1, DF2, DF3 for control for the temperature in the chamber.
