Abstract:
1. A temperature control apparatus for a heater using an encoder switch that controls an indoor temperature by driving a burner in accordance with a change of the indoor temperature and ventilating heated air indoors, the apparatus comprising: (a) an encoder switch for converting a user's set temperature value into a digital signal of a predetermined number of bits; (b) a microcomputer for comparing the indoor temperature inputted in real time with the user's set temperature, the microcomputer operative to drive the burner if the indoor temperature is lower than the set temperature by more than a predetermined temperature T (c) a display unit for checking and displaying various kinds of error modes occurring while the burner is driven in accordance with a control signal inputted from the microcomputer, (d) a temperature display selection unit for selectively displaying the indoor temperature displayed through the temperature display unit by Celsius (C) or Fahrenheit (F); (e) a fire sensing unit for sensing an ignition state of the burner by sensing a fire sensitivity in the burner; (f) a thermistor for sensing the indoor temperature changed in real time; (g) a temperature sensing unit for sensing a temperature of the burner that rises according to a combustion operation of the burner; wherein the display unit comprises: wherein the microcomputer checks:
