10.2.6 Ultraheat additional electric heater
The Ultraheat additional electric heater is built-in to the hot-air heater. Therefore
there are three heating options:
z Only the hot-air heater
z Hot-air heater and electric heater
z Only the electric heater
The vehicle can be heated more quickly with the additional electric heater.
Z Select the output level during 230 V electrical operation in such a way that it
corresponds to the 230 V connection protection:
Level 1 (1050 W) at 6 A
Level 2 (2100 W) at 10 A
Level 3 (3150 W) at 16 A
Z If gas and 230 V electrical operation is selected and if the vehicle is connected
to the 230 V power supply, then the hot-water heater at first only operates in
230 V electrical operation. Only if the heat output is insufficient, does the gas
operation also automatically switch on.
Z The gas operation is only possible when the regulator tap on the gas bottle and
the gas isolator tap are opened.
Z 230 V electrical operation is only possible when the vehicle is connected to the
230 V power supply.
Z Level 2 = Normal level
Z Level 5 = Ventilation
Z The additional electric heater only operates if the vehicle is connected to the
230 V power supply.
Z If the heater is operated simultaneously with current and gas, the additional
electric heater switches off before possible overheating by the stronger gas
burner occurs.
