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