Good evening an Happy New Year!
I am new to the forum and I accessed it already quite often for valuable info.
I own from a few months already a Hanse 350 from 2008.
I am still surprised that Hanse does not provide (basic) electric diagrams, water installation, etc. Can anybody help? Maybe with home-made sketches?
That would probably solve some of the stupid questions I frequently ask myself. Like this one:
I have a red light switch under the chart table, by the 220 socket. It seems to depict a thermometer in water... is this the heater switch?
Does it have to do with the 220v circuit?
Thank you!

Yes, this is the breaker switch to the water heater which on my boat is placed under the aft bunk. I guess that in Santoņa you dont have to worry about frozen water, but in my latitudes in wintertime, we blow the water out of the pipes, and empty the water heater. For safety reasons I also remove the 230V plug near the heater.

also has a few things for the H350.
Try to scroll down the topics in the 350 forum, there are 15 pages with valuable information.

Good evening to all again.
One quick question about the switches panel.
What is the purpose of the switch in the bottom right column?

That is for the bilge pump:
m - manual operation (on)
0 - off
a - automatic (operates when the float switch is activated).
