Buttons for what ????

[Lanerboy]

Hi all
Can someone please tell me what these buttons in the passenger side football area on my carthago do.

Am I correct in thinking the top picture is a heater for passenger feet area.

Is the next picture the heat exchanger button for getting the Alde heating hot in the back whilst driving

The bottom picture is just a larger shot of the middle picture is the top right button I'm interested in

Top picture is , I think, to operate an inline fan in the truma ducting to increase the air flow from a vent. It is either off, slow or fast. See link for picture

I think you are correct but my wife put it on last night on our way home and could not tell any difference

the truma vent is to blow heated air on the windscreen
the alde is the heat exchanger i believe
the other may be a supplementary heater

Your Carthago must be a lot bigger than ours was if your passenger can play football in it!

The Truma multivent switch is for a booster fan.
On my C-Line it is mounted on the side of the drivers seat to blow extra warm air over my feet while driving. Never needed to use it in the last four years.
I presume you also have an extra radiator/ fan under the seat or somewhere similar.
