Claim 0:
1. A method to retrofit a transparent window mounted on a vehicle, which window does not comprise an electric heating device, with a transparent window having an electric heating device, the method comprising:
a. removing from the vehicle the transparent window which does not comprise an electric heating device;
b. installing a transparent window, provided with an electric heating device and at least one temperature sensor, to obtain a retrofitted heating transparent window;
c. connecting the electric heating device to a voltage supply device and applying a heating voltage to the transparent window;
d. measuring a window temperature before an initial application of a heating voltage, and terminating the method if the window temperature exceeds a lower temperature threshold value and wherein the heating voltage and a heating period are selected such that a heating power corresponding to a resistance less than 10 ohms (Ω) per square meter (m2) of window area is generated;
e. applying a heating voltage between 30 and 60 volts to the heating device to apply a heating power corresponding to a resistance less than 10 ohms (Ω) per square meter (m2) of window area; and
f. connecting a remote control device with the at least one temperature sensor and the voltage supply device,
wherein the electric heating device is used for de-icing and/or defogging the retrofitted transparent window.
