Hello, I recently became owner of a Hanse 385 and I am still in the process of understanding some of the details of the boat. Thus I'd be greatful for a quick explanation of the function of the big black relay on the main power board. Written on it is 'CR 70' and 'Truma FRC3A-V'.  I understood the use of most of the rest of the connections on the board, but not this one.
I found a drawing of the power board on the search, but this drawing seems to show a more recent version (v.2). As my boat is from 2013, it might be and older version. This said, if somebody happens to have the technical drawing of this board, I'd be very grateful. Thank you for your help! |

I believe this relay runs the engine compartment blower. You can easily test it by removing the fuse and observing the blower. ------------- Leon / ARCADIA 2018 Hanse 588 Sag Harbor, NY |

Hello, thanks a lot, I will check this once I am on board. That could indeed be the ventilation. I'd first thought it'd be the control panel of the engine, but this was not the case.
