Hey, i have installed new D 4 airheater (fabr nr 394755CA ) in my boat.
the only control unit is EasyStart T and roomtemperature sensor in
cabin.The heater takes fresh air outside of the boat, so how must
electric wiring connect that the temperature is adjusted by the cabin
temperaturesensor and not by airtronics inner sensor. I have made
wiring by circuit diagram nr 25 2361 00 97 03 A upper part, and now
temperature is adjusted by airtronics internal sensor and that not
works in my boat because i take fresh air outside of the boat.
EasyStart shows cabins temperature and temperature what i have
installed to be in cabin("thermostat reading"Adjustments in EasyStart
are made correct.So what wire i must connect to EasyStartT to get
working?

kad,

No problem on the Language, Electrical Schematics are the same in any language.

On page 32, find the Fuse #2.7.
This appears to be the line for the internal sensor circuit.

I'd remove the Fuse, turn the temp up to High in the unit, and see if the unit operated when you just used a Jumper Wire across the Fuse Clips (just to check it).

If this turns the Unit on/off, then you could install the Cabin sensor in-line with that fuse.

HOWEVER !!!
I do NOT know what the Amperage is for that line, and you might overload the Cabin Sensor Contacts.
My best guess.

Have a good Day !
