A temperature detection, a thermostat for heating and a temperature control method used for the same are provided to compose a trigger connection part to switch alternately the current flow for detecting temperature and a heating process, by a simplified structure instead of a rectifying diode. A temperature signal voltage supply controller(100) controls supply of the temperature signal voltage, and is connected to a first heating wire(1) and a second heating wire and a heating line(10) including an NTC thermistor(2). A thermostat(300) outputs a temperature control signal by comparing a standard voltage and the temperature signal voltage outputted from the first heating wire. An U-turn rectifying part(17) returns the heating current toward a power source. The thermostat comprises a trigger generator(400), a trigger connection part(200) and a control rectifier(13). |
