The window heating timers U6046B are bipolar integrated circuits. Due to time controlled functions, they reduce the current consumptions of high loads i.e., heating resistors.
An ON-relay U6046B can be switched off after a preset delay time. The relay time can be interrupted manually, whereas a retrigger function is not provided.
