Defrosting control function:
This function is available only on models with 2 LCD: 8AJ033, 8AJ033A, 8AG033A, 8AG033B and
8ME033B.
Operates by short presses (pulses) on the defrosting control.
Ignition on and pulse on the defrosting command: control of the defrosting relay starts for 12
minutes (720 seconds) with the associated lamp lit, except for the electric model which has a
timeout of 4 minutes (240 seconds).
If an additional pulse is produced or if ignition is switched off, control is cancelled and the lamp
switches off.
Protection function:
The defrosting output is protected. If battery voltage exceeds 16 Volts, the function is inhibited,
and is restored when the voltage drops below 15.7 Volts.
Engine off control:
When the ignition is off, the dashboard activates the engine off relay for 8 seconds. Then the
dashboard "falls asleep".
The engine off relay is controlled by ignition off.
Lights on alarm:
If ignition is off, the car lights are lit: when opening the door the dashboard emits a signal at a
frequency of 2581 Hz.
This sound signal overrides the warning lights beep.
