Temperature-controlled automatic switch-on.
When Automatic switch-on is selected, the sensor will take the outside temperature and decide the
correct switch-on time in relation to the programmed drive away time. Lower temperatures require
longer warming up periods to reach the required engine and interior temperatures. The graph (IV)
shows the on-time in minutes at different outside temperatures. Note that the on-time is always
related to programmed drive away time.
If the vehicle is not started at the programmed drive away time, the on-time is automatically extended
by 2 hours (Oversleep function). When the car is started the remaining on-time and the oversleep
function are automatically erased.
Programming the time / drive away time and calibration of the outside temperature.(V).
1. Press until the display shows the wanted function.
2. Press both arrow buttons
Selected function starts to blink
3. Set the time / away time or calibrate the temperature by using the arrow buttons.
The temperature might be adjusted until +/- 3ºC. To achieve precise calibration of the
outside temperature, calibration should take place at 0ºC.
To save the chosen function – wait for 5 seconds until the blinking stops. If you only want one drive
away time, program I and II so that they coincide. When the control unit switches on the DEFA
Warm Up, the 'On' symbol blinks on the display.
0-condition warning ( Optional temp sencor 418071)
The control unit is equipped with a 0-condition warning, which will warn you when the vehicle enters
an area where slippery conditions are likely. An outside sensor must be fitted for this function to
work. If the vehicle enters an area where the temperature sinks below 4ºC or raises past - 4ºC, the
light on the display and the buttons blink rapidly for approximately 6 seconds. At the same time
the temperature is shown for 15 seconds. The control unit can not be otherwise used when this
ice-warning is active.
Starting the engine
When the engine is started any remaining on-time is erased and the "On" symbol in the display is
extinguished. The control unit carries out an information sequence that displays: Battery voltage
before start, charging voltage after start and outside temperature (approximately 2 seconds for
each function). At the end the control unit returns to the function selected before the information
sequence.
Switching off the engine
When the engine is switched off, the control unit carries out an information sequence showing drive
away time I and drive away time II before returning to the function selected before the information
sequence.
Display illumination
The illumination of the control unit display will always be turned on when one of the buttons is
pressed. The display will be illuminated for approximately 1 minute after the last button is pressed.
Depending on the usefulness of the information displayed by the control unit, the illumination can
be turned ON or OFF during driving.Illuminated display during driving:
Press for up to 3 seconds. The display light will blink to confirm that the light will come on.
