PURPOSE: A temperature controller and a control method thereof are provided to prevent fire generation due to overhead of an electric mat by performing power returning mode. CONSTITUTION: A power supply unit(10) supplies a driving power to an electronic circuit unit. A temperature sensor(11) is connected to a heating wire in order to sense the temperature. An LED drive(20) turns on a light emitting diode in a power supply process. An operation unit(30) operates an operating time, temperature set up, and an electric power supply. A display unit(60) displays the operation state of the electricity warm mat. An MPU(40) maintains a fixed temperature by controlling power supplied on a heating line. A drive(50) drives a display unit with the control of the MPU. |
