While driving, the slider should be set to the “down” or “blue” position, otherwise warm air from the
engine heat exchanger would flow out of all the heating nozzles of the motorhome and the windscreen
would fog up (the amount of air flow from the window fans would be too small). When living, the slider
should be set to the “up” or “red” position.
Hot water heating (standard with Luxury version):
Your motorhome is equipped with an Alde hot water heater in combination with an engine heat exchanger. This gives you
the option of using both the engine heat for the Alde system and, conversely, preheating the engine.

To disconnect the radiator heating circuit from the body heating circuit, remove the
cover from the front passenger storage box and turn the black lever on the heat
exchanger downwards.
Function of hot water heating:
The control panel is located above the body door. It contains a main switch and a
MENU button. In idle mode, the temperature and time are displayed. Temperature
“A”, hot water “B”, electric heating “C” and heating with gas “D” are controlled in
the settings menu. There is also an access to the settings menu. All functions are
explained in the Alde operating instructions enclosed.
In the motorhome there is a temperature sensor in the control unit and another
in the living area. In the basic setting, the sensor is active in the living area when
entering.
The expansion tank for the heating circuit is in the wardrobe. The level should be
between the two markings (min., max.) in the operating state. If necessary, add
antifreeze directly to the expansion tank.
To avoid overfilling the system, the refilling may only be carried out while the heating
is running. The liquid in the heating circuit should be replaced after 3 years.
Only use antifreeze agents, glycol G13 or Glysofor N (VW TL 774 J), mixed 50:50 with distilled water,
which are approved for aluminium, otherwise the 2-year manufacturer’s guarantee will expire.
The heater has a built-in water heater with a capacity of approximately 8.5 litres of fresh water. Air can
collect in the pipes of the water heater, which should be let out at the vent screws (1) on the radiators
in the seating areas, in the kitchen in the washroom and in the bed area. An automatic vent valve “A” is
mounted directly on the flow.
The convectors in the rear bed area and in the alcove (depending on the floor plan) are connected to
the heating circuit by a so-called bypass (2) and can therefore be regulated separately via a valve that
is attached to the convector.
