Abstract
To provide a heater control apparatus capable of checking, during initial installation, whether heaters and temperature sensors are connected together so as to be correctly paired, and whether the outputs from the temperature sensors are correct. The present invention is characterized in that a heater control apparatus comprises a large number of heaters, each provided so as to correspond to each of a large number of yarn processing units installed in parallel; a large number of temperature sensors each provided so as to pair with each of the heaters and detecting the temperature of the heaters; a large number of switches each provided so as to pair with each of the heaters and turning on and off the power to the heaters; a switch control device for sequentially turning on and off the large number of switches to sequentially provide power to the large number of heaters; and a combination determining device for determining whether a temperature sensor that has detected the temperature of an activated heater should be paired with said heaters.
