When the warming unit is turned on, the temperature of the waste water pipes
is monitored by temperature sensors. If the temperature falls below 5 °C, the
heating elements are switched on and the waste water pipes are warmed. If
the temperature rises above a certain level, the heating elements are switched
off again.
The 240 V AC/12 V DC transformer (Fig. 121,2) is installed in the wardrobe.
The control unit is integrated in the transformer housing. The control lamps
have the following meanings:
The indicator lamp (Fig. 121,5) lights up in green: Regulation in operation
Red indicator lamps (Fig. 121,4 and 6) illuminate: Waste water pipes are
warmed
A test button (Fig. 121,3) is integrated in the housing with which the control
unit can be operated for a short time. By pressing the test button, the function
of the warming unit can be tested, even if the ambient temperature is above
5°C.
Switching on:
Connect the vehicle to a 240 V power supply (see section 9.7.1).
Turn switch (Fig. 121,1) on the transformer (Fig. 121,2) to "ON".
Switching off:
Turn switch (Fig. 121,1) on the transformer (Fig. 121,2) to "OFF".
10.2.7 Electrical floor warming unit
The regulator for the electrical floor warming unit is installed in the bench seat
or in the wardrobe, depending on the model.
Fig. 121 Transformer with control unit
On models with electrical floor warming unit, never drill holes in the floor
or screw in any screws. Careful with sharp objects. There is danger of a
power cut or a short circuit due to damage to a heater wire.
Do not cover the regulator. Danger of overheating!
The electrical floor warming unit only operates if the vehicle is connected
to the 240 V power supply.
The output of the electrical floor warming unit alone is not sufficient to heat
the living area.
