Heated rear screen time delay
This output controls a diode relay which is external to the UCH, delivering the power to supply the heated rear
screen.
The de-icing time delay is activated by pressing the heated rear screen button located on the central console front
panel.
The heated rear screen time delay is deactivated:
– by pressing the button again if the time delay between activation and deactivation is less than 50 seconds,
– automatically if the time delay has elapsed,
– directly if there is a cut in the + after ignition feed or engine speed signal.
The minimum time delay between two presses of the button so that the command is taken into account, should not
be less than 200 ms.
