Variant: Heater with gas
and 230 V electrical
operation
The heater can be operated with different types of energy:
z Gas operation (Fig. 83,3)
z 230 V electrical operation with the output levels 900 W (Fig. 83,2) or
1800 W (Fig. 83,1)
z Gas operation and 230 V electrical operation (mixed operation) with the
output levels 900 W (Fig. 83,4) or 1800 W (Fig. 83,5)
The combination gas operation and 230 V electrical operation reduces the
heating-up time (only possible when the heater on the operating unit (Fig. 82)
is set to winter operation).
When 230 V electrical operation has been selected, the yellow indicator lamp
(Fig. 83,6) lights up.
Z 230 V electrical operation is only possible when the vehicle is connected to
the 230 V power supply.
Z Select the output level for 230 V electrical operation so that it corresponds
to the fuse protection of the 230 V connection (900 W for 3.9 A fuse, 1800
W for 7.8 A fuse).
Z If the heater is set at the operating unit to "Summer" operation and the
energy selector switch is set to mixed operation, the heater nevertheless
operates only in 230 V operation. The gas burner is not switched on.
