Patent ID: 7654733

Claim:
A method for identifying a temperature sensor of a heating device, wherein said temperature sensor is positioned so as to be directly heated by said heating device, wherein said temperature sensor is connected to a control unit and evaluated by said control unit, comprising the steps of: measuring a resistance value of said connected temperature sensor in response to connecting said control unit to an operating voltage; comparing said resistance value with at least one preset limit value, wherein said preset limit value characterizes at least two different groups of temperature sensors with respect to said resistance value of said at least two different groups of temperature sensors; classifying said temperature sensor as belonging to a first group of temperature sensors if said resistance value exceeds said limit value and classifying said temperature sensor as belonging to a second group of temperature sensors if said resistance value is below said limit value; and controlling and evaluating said temperature sensor by said control unit by using calibration data to calibrate said temperature sensor using said resistance value according to one of said groups of said temperature sensors.
