METHOD FOR OPERATING A GLOW IGNITION DEVICE OF A CAR HEATER AT STARTUP OF THE CAR HEATER

The method for the operating of an incandescent igniter element of a vehicle's heater in the starting phase entails the recording a value in dependence upon a heating capacity of the igniter element (12), comparing this value with a reference, and if the value is less than the reference increasing the heating capacity of the incandescent igniter element. In the first stage the value which is in dependence upon the heating capacity is based on a voltage applied to the igniter element and current flowing through it.
