0%to 100 %(corresponds to 4.5 V and 0.5 V )depending on sunlight penetration intensity.
Notes (display zones 1, 2 and 3):
◆ The basis for the display in display zone 1 is the lower of the two measured ambient temperatures (=>Display
zones 2 and 3). When the ignition is switched off, the value is stored up to 4 hours.
◆ The measured value from a defective temperature sensor is suppressed by -E87, and -E87 then uses an
internal calculated value for the further control.
Notes on display zone 4:
◆ The display value for photosensor -G107 may be changed by shining an appropriate bulb at the sensor.
◆ If, irrespective of the light conditions for photosensor -G107, the display always shows about 90 % or approx.
1V of the maximum sunlight penetration, use the current flow diagram to check the cabling to photosensor
-G107 for interchanges.
