The Electronic Display Unit (EDU) control module sends a temperature signal to the Automatic Climate Control (ACC) unit on pin 23. The signal
consists of a series of pulses where the number of pulses indicates the temperature. The pulse series are separated from each other by a pause of at least
400 ms so that the ACC unit has time to register the end of each series.
