Fig. 88: ALDE turbo convector
The ALDE switch for the heat exchanger is fitted on the driver’s
side on the left next to the steering wheel.
Function:
Preselect level “I” or “OFF” via the button
Press once = level “I”, press once more = “OFF”.
LED level “I” illuminates if ready for operation.
LED “ON” illuminates if level “I” is selected and 12V is
applied at the release signal.
The release signal originates from the Alde heater (circulation
pump in operation) so that only hot water reaches the engine.
LED “I” = green
LED “ON” = yellow
ALDE heat exchanger (optional)
Fig. 89: ALDE heat exchanger
The ALDE heat exchanger (optional) is used to heat the motor
home when travelling. The heat exchanger can be found behind
the driver's seat.
An extended cooling water hose is used to connect the heat
exchanger to the engine's cooling system. While driving, the
heated engine cooling water flows through the heat exchanger –
assuming the switch is opened – and heats the heating liquid
pumped in by the recirculation pump of the ALDE heater
(glycol/water mixture).
