PURPOSE: An apparatus for driving the direct action of deviation in a digital temperature controlling system and a method for driving the same are provided to easily check a voltage-current data for the value of setting temperature when a furnace installed in a factory is after serviced. CONSTITUTION: An apparatus for driving the direct action of deviation in a digital temperature controlling system includes a noise filter(10), a digital temperature controller(12), a silicon controlled rectifier(SCR)(20), a power transformer(16), a heater(22), a fan(26) and a motor controller(14). In the apparatus, the noise filter(10) removes the noise of an external input power and the digital temperature controller(12) maintains and controls the temperature constant by using a proportional, integral and differential controls. The SCR(20) implements the power control and temperature control by the control signal from the digital temperature controller(12). The power transformer(16) detects the used amount of the power by detecting the current and the voltage and the heater(22) heats the target resistor. And, the fan(26) prevents the target resistor from being over heated and the motor controller(14) controls the drive of the fan(26).
